Routes makes it easy to create pretty and concise URL's that are RESTful with little effort. Speedy and dynamic URL generation means you get a URL with minimal cruft (no big dangling query args). Shortcut features like Named Routes cut down on repetitive typing.

Patch by Davanum Srinivas (PR #65). Release 2.3 (March 28, 2016) ============================ * Fix sub_domain equivalence check. Patch by Nikita Uvarov * Add support for protocol-relative URLs generation (i.e. starting with double slash ``//``). PR #60. Patch by Sviatoslav Sydorenko. * Add support for the ``middleware`` extra requirement, making possible to depend on ``webob`` optionally. PR #59. Patch by Sviatoslav Sydorenko. * Fix matching of an empty string route, which led to exception in earlier versions. PR #58. Patch by Sviatoslav Sydorenko. * Add support for the ``requirements`` option when using mapper.resource to create routes. PR #57. Patch by Sean Dague. * Concatenation fix when using submappers with path prefixes. Multiple submappers combined the path prefix inside the controller argument in non-obvious ways. The controller argument will now be properly carried through when using submappers. PR #28. Release 2.2 (July 21, 2015) =========================== * Fix Python 3 support. Patch by Victor Stinner. Release 2.1 (January 17, 2015) ============================== * Fix 3 other route matching groups in route.py to use anonymous groups for optional sections to avoid exceeding regex limits. Fixes #15. * Printing a mapper now includes the Controller/action parameters from the route. Fixes #11. * Fix regression that didn't allow passing in params 'host', 'protocol', or 'anchor'. They can now be passed in with a trailing '_' as was possible before commit d1d1742903fa5ca24ef848a6ae895303f2661b2a. Fixes #7. * URL generation with/without SCRIPT_NAME was resulting in the URL cache failing to return the appropriate cached URL generation. The URL cache should always include the SCRIPT_NAME, even if its empty, in the cache to avoid this, and now does. Fixes #6. * Extract Route creation into separate method in Mapper. Subclasses of Route can be created by Mappers now. * Use the first X_FORWARDED_FOR value if there are multiple proxies in the path. Fixes #5. Release 2.0 (November 17, 2013) =============================== * Python 3.2/3.3 Support. Fixes Issue #2. Thanks to Alejandro Sánchez for the pull request! Release 1.13 (March 12, 2012) ============================= * Fix bug with dots forcing extension by default. The portion with the dot can now be recognized. Patch by Michael Basnight. Release 1.12.3 (June 5, 2010) ============================= * Fix bug with URLGenerator not properly including SCRIPT_NAME when generating URL's and the singleton is not present. Release 1.12.2 (May 5, 2010) ============================ * Fix bug with routes URLGenerator not properly including SCRIPT_NAME when generating qualified URL's. Release 1.12.1 (March 11, 2010) =============================== * Fix bug with routes not generating URL's with callables in defaults. * Fix bug with routes not handling sub-domain defaults during generation. Release 1.12 (February 28, 2010) ================================ * Split up the Routes docs. * Fix bug with relative URL's using qualified merging host and URL without including the appropriate slash. Fixes #13. * Fix bug with mapper.extend and Routes modifying their original args. Fixes #24. * Fix url.current() not returning current args when explicit is True. * Added explicit way to directly use the Mapper to match with environ. * Fix bug with improper len placement for submapper. * Adding regular expression builder for entire regexp for faster rejection in a single regexp match should none of the routes match. * Give Mapper a tabular string representation. * Make SubMapper objects nestable and add route-generation helpers. * Add SubMapper-based collections. * Make the deprecated Mapper.minimization False (disabled) by default. * Make the mapper explicit (true) by default. Release 1.11 (September 28, 2009) ================================= * Extensive documentation rewrite. * Added Mapper.extend function that allows one to add lists of Routes objects to the mapper in one batch, optionally with a path_prefix. * Added Mapper.submapper function that returns a SubMapper object to enable easier declaration of routes that have multiple keyword argument options in common. * Mapper controller_scan argument now handles None, and lists of controller names in addition to a callable. * Route object now takes a name parameter, which is the name it responds to. This name is automatically added when called by using Mapper's connect class method. * Added optional LRU object for use with Routes when URL's change too often for the Routes urlcache dict to be a viable option. Release 1.10.3 (February 8, 2009) ================================= * Tweak to use WebOb Request rather than Paste. * Performance tweaks for URL recognition. * Bugfix for routes.middleware not re.escaping the path_info before moving it to the script name. Release 1.10.2 (January 11, 2009) ================================= * Bugfix for unicode encoding problems with non-minimized Route generation. Spotted by Wichert Akkerman. * Bugfix for when environ is {} in unit tests. Release 1.10.1 (September 27, 2008) =================================== * Removing LRU cache due to performance and threading issues. Cache does hit a max-size for the given routes. Release 1.10 (September 24, 2008) ================================= * Adding LRU cache instead of just dict for caching generated routes. This avoids slow memory leakage over long-running and non-existent route generation. * Adding URLGenerator object. * Adding redirect routes. * Static routes can now interpolate variable parts in the path if using {} variable part syntax. * Added sub_domain condition option to accept False or None, to require that there be no sub-domain provided for the route to match. Release 1.9.2 (July 8, 2008) ============================ * Fixed bug in url_for which caused it to return a literal when it shouldn't have. Release 1.9.1 (June 28, 2008) ============================= * Fixed bug in formatted route recognition with formatting being absorbed into the id. Release 1.9 (June 12, 2008) =========================== * Fix undefined arg bug in url_for. * Fixed bug with url_for not working properly outside of a request when sub-domains are active. Thanks Pavel Skvazh. * Add non-minimization option to Routes and the Mapper for generation and recognition. * Add Routes 2.0 style syntax for making routes and regexp. For example, this route will now work: '{controller}/{action}/{id}'. * Fixed Routes to not use quote_plus when making URL's. * WARNING: Mapper now comes with hardcode_names set to True by default. This means routes generated by name must work for the URL. * Actually respect having urlcache disabled. * WARNING: Calling url_for with a set of args that returns None now throws an exception. Code that previously checked to see if a url could be made must be updated accordingly. * Updated url_for to return url in a literal for use in templating that may try to escape it again. * Added option to use X_FORWARDED_PROTO for proxying behind https to work easier. * Fixed map.resource to be less restrictive on id than just spaces. * Fixed Mapper.create_regs not being thread safe, particularly when always_scan=True. Release 1.8 (March 28, 2008) ============================ * Fixed bug of map.resource not allowing spaces in id. * Fixed url generation to properly handle unicode defaults in addition to unicode arguments. * Fixed url_for to handle lists as keyword args when generating query parameters. * WARNING: Changed map.resource to not use ';', for actions, but the normal '/'. This means that formatted URL's will also now have the format come AFTER the action. Ie: /messsages/4.xml;rss -> /messages/4/rss.xml Release 1.7.3 (May 28th, 2008) ============================== * Fixed triple escaping bug, since WSGI servers are responsible for basic unescaping. Release 1.7.2 (Feb. 27th, 2008) =============================== * Fixed bug with keyword args not being coerced to raw string properly. Release 1.7.1 (Nov. 16th, 2007) =============================== * Fixed bug with sub-domains from route defaults getting encoded to unicode resulting in a unicode route which then caused url_for to throw an exception. * Removed duplicate assignment in map.resource. Patch by Mike Naberezny. * Applied test patch fix for path checking. Thanks Mike Naberezny. * Added additional checking of remaining URL, to properly swallow periods in the appropriate context. Fixes #57. * Added mapper.hardcode_names option which restricts url generation to the named route during generation rather than using the routes default options during generation. * Fixed the special '_method' attribute not being recognized during POST requests of Content-Type 'multipart/form-data'. Release 1.7 (June 8th, 2007) ============================ * Fixed url_unquoting to only apply for strings. * Added _encoding option to individual routes to toggle decoding/encoding on a per route basis. * Fixed route matching so that '.' and other special chars are only part of the match should they not be followed by that character. Fixed regexp creation so that route parts with '.' in them aren't matched properly. Fixes #48. * Fixed Unicode decoding/encoding so that the URL decoding and encoding can be set on the mapper with mapper.encoding. Fixes #40. * Don't assume environ['CONTENT_TYPE'] always exists: it may be omitted according to the WSGI PEP. * Fixed Unicode decode/encoding of path_info dynamic/wildcard parts so that PATH_INFO will stay a raw string as it should. Fixes #51. * Fixed url_for (thus redirect_to) to throw an exception if a Unicode string is returned as that's an invalid URL. Fixes #46. * Fixed Routes middleware to only parse POST's if the content type is application/x-www-form-urlencoded for a HTML form. This properly avoids parsing wsgi.input when it doesn't need to be. Release 1.6.3 (April 10th, 2007) ================================ * Fixed matching so that an attempt to match an empty path raises a RouteException. Fixes #44. * Added ability to use characters in URL's such as '-' and '_' in map.resource. Patch by Wyatt Baldwin. Fixes #45. * Updated Mapper.resource handling with name_prefix and path_prefix checking to specify defaults. Also ensures that should either of them be set, they override the prefixes should parent_resource be specified. Patch by Wyatt Baldwin. Fixes #42. * Added utf-8 decoding of incoming path arguments, with fallback to ignoring them in the very rare cases a malformed request URL is sent. Patch from David Smith. * Fixed treatment of '#' character as something that can be left off and used in route paths. Found by Mike Orr. * Added ability to specify parent resource to map.resource command. Patch from Wyatt Baldwin. * Fixed formatted route issue with map.resource when additional collection methods are specified. Added unit tests to verify the collection methods work properly. * Updated URL parsing to properly use HTTP_HOST for hostname + port info before falling back to SERVER_PORT and SERVER_NAME. Fixes #43. * Added member_name and collection_name setting to Route object when made with map.resource. * Updated routes.middleware to make the Routes matched accessible as environ['routes.route']. * Updating mapper object to use thread local for request data (such as environ) and middleware now deletes environ references at the end of the request. * Added explicit option to Routes and Mapper. Routes _explicit setting will prevent the Route defaults from being implicitly set, while setting Mapper to explicit will prevent Route implicit defaults and stop url_for from using Route memory. Fixes #38. * Updated config object so that the route is attached if possible. * Adding standard logging usage with debug messages. * Added additional test for normal '.' match and fixed new special matching to match it properly. Thanks David Smith. * Fixed hanging special char issue with 'special' URL chars at the end of a URL that are missing the variable afterwards. * Changed Routes generation and recognition to handle other 'special' URL chars , . and ; as if they were /. This lets them be optionally left out of the resulting generated URL. Feature requested by David Smith. * Fixed lookahead assertion in regexp builder to properly handle two grouped patterns in a row. * Applied patch to generation and matching to handle Unicode characters properly. Reported with patch by David Smith. Release 1.6.2 (Jan. 5, 2007) ============================ * Fixed issue with method checking not properly handling different letter cases in REQUEST_METHOD. Reported by Sean Davis. * redirect_to now supports config.redirect returning a redirect, not just raising one. Release 1.6.1 (Dec. 29, 2006) ============================= * Fixed zipsafe flag to be False. Release 1.6 (Dec. 14th, 2006) ============================= * Fixed append_slash to take effect in the route generation itself instead of relying on url_for function. Reported by ToddG. * Added additional url_for tests to ensure map.resource generates proper named routes. * WARNING: Changed map.resource initialization to accept individual member and collection names to generate proper singular and plural route names. Those using map.resource will need to update their routes and url_for statements accordingly. * Added additional map.resource recognition tests. * Added WSGI middleware that does route resolving using new `WSGI.org Routing Vars Spec `_. * Added _absolute keyword option route connect to ignore SCRIPT_NAME settings. Suggested by Ian Bicking. Release 1.5.2 (Oct. 16th, 2006) =============================== * Fixed qualified keyword to keep host port names when used, unless a host is specifically passed in. Reported by Jon Rosebaugh. * Added qualified keyword option to url_for to have it generate a full URL. Resolves #29. * Fixed examples in url_for doc strings so they'll be accurate. Release 1.5.1 (Oct. 4th, 2006) ============================== * Fixed bug with escaping part names in the regular expression, reported by James Taylor. Release 1.5 (Sept. 19th, 2006) ============================== * Significant updates to map.resource and unit tests that comb it thoroughly to ensure its creating all the proper routes (it now is). Increased unit testing coverage to 95%. * Added unit tests to ensure controller_scan works properly with nested controller files and appropriately scans the directory structure. This brings the Routes util module up to full code coverage. * Fixed url_for so that when the protocol is changed, port information is removed from the host. * Added more thorough testing to _RequestConfig object and the ability to set your own object. This increases testing coverage of the __init__ module to 100%. * Fixed bug with sub_domain not maintaining port information in url_for and added unit tests. Reported by Jonathan Rosebaugh. * Added unit tests to ensure sub_domain option works with named routes, cleaned up url_for memory argument filtering. Fixed bug with named routes and sub_domain option not working together, reported by Jonathan Rosebaugh. * Changed order in which sub-domain is added to match-dict so it can be used in a conditions function. Release 1.4.1 (Sept. 6th, 2006) =============================== * Added sub_domains option to mapper, along with sub_domains_ignore list for subdomains that are considered equivilant to the main domain. When sub_domains is active, url_for will now take a sub_domain option that can alter the host the route will go to. * Added ability for filter functions to provide a _host, _protocol, _anchor arg which is then used to create the URL with the appropriate host/protocol/anchor destination. * Patch applied from Ticket #28. Resolves issue with Mapper's controller_scan function requiring a valid directory argument. Submitted by Zoran Isailovski. Release 1.4 (July 21, 2006) =========================== * Fixed bug with map.resource related to member methods, found in Rails version. * Fixed bug with map.resource member methods not requiring a member id. * Fixed bug related to handling keyword argument controller. * Added map.resource command which can automatically generate a batch of routes intended to be used in a REST-ful manner by a web framework. * Added URL generation handling for a 'method' argument. If 'method' is specified, it is not dropped and will be changed to '_method' for use by the framework. * Added conditions option to map.connect. Accepts a dict with optional keyword args 'method' or 'function'. Method is a list of HTTP methods that are valid for the route. Function is a function that will be called with environ, matchdict where matchdict is the dict created by the URL match. * Fixed redirect_to function for using absolute URL's. redirect_to now passes all args to url_for, then passes the resulting URL to the redirect function. Reported by climbus. Release 1.3.2 (April 30th, 2006) ================================ * Fixed _filter bug with inclusion in match dict during matching, reported by David Creemer. * Fixed improper url quoting by using urllib.encode, patch by Jason Culverhouse. Release 1.3.1 (April 4th, 2006) =============================== * Mapper has an optional attribute ``append_slash``. When set to ``True``, any URL's generated will have a slash appended to the end. * Fixed prefix option so that if the PATH_INFO is empty after prefix regexp, its set to '/' so the match proceeds ok. * Fixed prefix bug that caused routes after the initial one to not see the proper url for matching. Caught by Jochen Kupperschmidt. Release 1.3 (Feb. 25th, 2006) ============================= * url_for keyword filters: Named routes can now have a _filter argument that should specify a function that takes a dict as its sole argument. The dict will contain the full set of keywords passed to url_for, which the function can then modify as it pleases. The new dict will then be used as if it was the original set of keyword args given to url_for. * Fixed Python 2.3 incompatibility due to using keyword arg for a sort statement when using the built-in controller scanner. Release 1.2 (Feb. 17th, 2006) ============================= * If a named route doesn't exist, and a url_for call is used, instead of using the keyword arguments to generate a URL, they will be used as query args for the raw URL supplied. (Backwards Incompatible) * If Mapper has debug=True, using match will return two additional values, the route that matched, if one did match. And a list of routes that were tried, and information about why they didn't pass. * url_for enhancements: Can now be used with 'raw' URL's to generate proper url's for static content that will then automatically include SCRIPT_NAME if necessary Static named routes can now be used to shortcut common path information as desired. * Controller Scanner will now sort controller names so that the longest one is first. This ensures that the deepest nested controller is executed first before more shallow ones to increase predictability. * Controller Scanner now scans directories properly, the version in 1.1 left off the directory prefix when created the list of controllers. (Thanks to Justin for drawing my attention to it) Release 1.1 (Jan. 13th, 2006) ============================= * Routes Mapper additions: Now takes several optional arguments that determine how it will generate the regexp's. Can now hold a function for use when determining what the available controllers are. Comes with a default directory scanner Given a directory for the default scanner or a function, the Mapper will now automatically run it to get the controller list when needed * Syntax available for splitting routes to allow more complex route paths, such as ':controller/:(action)-:(id).html' * Easier setup/integration with Routes per request. Setting the environ in a WSGI environ will run match, and setup everything needed for url_for/etc. Release 1.0.2 (Dec. 30th, 2005) =============================== * Routes where a default was present but None were filling in improper values. * Passing a 0 would evaluate to None during generation, resulting in missing URL parts Release 1.0.1 (Dec. 18th, 2005) =============================== * Request Local Callable - You can now designate your own callable function that should then be used to store the request_config data. This is most useful for environments where its possible multiple requests might be running in a single thread. The callable should return a request specific object for attributes to be attached. See routes.__init__.py for more information. Release 1.0 (Nov. 21st, 2005) ============================= * routes.__init__ will now load the common symbols most people will want to actually use. Thus, you can either:: from routes import * Or:: from routes import request_config, Mapper The following names are available for importing from routes:: request_config, Mapper, url_for, redirect_to * Route Names - You can now name a route, which will save a copy of the defaults defined for later use by url_for or redirect_to. Thus, a route and url_for looking like this:: m.connect('home', controller='blog', action='splash') url_for(controller='blog', action='splash') # => /home Can now be used with a name:: m.connect('home_url','home', controller='blog', action='splash') url_for('home_url') # => /home Additional keywords can still be added to url_for and will override defaults in the named route. * Trailing / - Route recognition earlier failed on trailing slashes, not really a bug, not really a feature I guess. Anyways, trailing slashes are o.k. now as in the Rails version. * redirect_to now has two sets of tests to ensure it works properly Keywords: routes webob dispatch Platform: UNKNOWN Classifier: Development Status :: 5 - Production/Stable Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: MIT License Classifier: Topic :: Internet :: WWW/HTTP Classifier: Topic :: Software Development :: Libraries :: Python Modules Classifier: Programming Language :: Python :: Implementation :: PyPy Classifier: Programming Language :: Python :: Implementation :: CPython Classifier: Programming Language :: Python Classifier: Programming Language :: Python :: 2 Classifier: Programming Language :: Python :: 2.6 Classifier: Programming Language :: Python :: 2.7 Classifier: Programming Language :: Python :: 3 Classifier: Programming Language :: Python :: 3.2 Classifier: Programming Language :: Python :: 3.3 Classifier: Programming Language :: Python :: 3.4 Classifier: Programming Language :: Python :: 3.5 Routes-2.3.1/setup.py0000644000175000017500000000450712676764157014075 0ustar benben00000000000000__version__ = '2.3.1' import io import os import sys from setuptools import setup, find_packages here = os.path.abspath(os.path.dirname(__file__)) with io.open(os.path.join(here, 'README.rst'), encoding='utf8') as f: README = f.read() with io.open(os.path.join(here, 'CHANGELOG.rst'), encoding='utf8') as f: CHANGES = f.read() PY3 = sys.version_info[0] == 3 extra_options = { "packages": find_packages(), } if PY3: if "test" in sys.argv or "develop" in sys.argv: for root, directories, files in os.walk("tests"): for directory in directories: extra_options["packages"].append(os.path.join(root, directory)) setup(name="Routes", version=__version__, description='Routing Recognition and Generation Tools', long_description=README + '\n\n' + CHANGES, classifiers=["Development Status :: 5 - Production/Stable", "Intended Audience :: Developers", "License :: OSI Approved :: MIT License", "Topic :: Internet :: WWW/HTTP", "Topic :: Software Development :: Libraries :: Python Modules", "Programming Language :: Python :: Implementation :: PyPy", "Programming Language :: Python :: Implementation :: CPython", 'Programming Language :: Python', "Programming Language :: Python :: 2", "Programming Language :: Python :: 2.6", "Programming Language :: Python :: 2.7", "Programming Language :: Python :: 3", "Programming Language :: Python :: 3.2", "Programming Language :: Python :: 3.3", "Programming Language :: Python :: 3.4", "Programming Language :: Python :: 3.5" ], keywords='routes webob dispatch', author="Ben Bangert", author_email="ben@groovie.org", url='http://routes.readthedocs.org/', license="MIT", test_suite="nose.collector", include_package_data=True, zip_safe=False, tests_require=['nose', 'webtest', 'webob', 'coverage'], install_requires=[ "six", "repoze.lru>=0.3" ], extras_require={ 'middleware': [ 'webob', ] }, **extra_options ) Routes-2.3.1/setup.cfg0000644000175000017500000000040012676765171014165 0ustar benben00000000000000[egg_info] tag_build = tag_date = 0 tag_svn_revision = 0 [nosetests] verbose = True verbosity = 1 detailed-errors = True with-doctest = True with-coverage = True cover-erase = True cover-html = True cover-html-dir = html_coverage cover-package = routes Routes-2.3.1/LICENSE.txt0000644000175000017500000000206612676764271014201 0ustar benben00000000000000Copyright (c) 2005-2016 Ben Bangert Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

A resource route addresses *members* in a *collection*, and the collection itself. Normally a collection is a plural word, and a member is the corresponding singular word. For instance, consider a collection of messages:: map.resource("message", "messages") # The above command sets up several routes as if you had typed the # following commands: map.connect("messages", "/messages", controller="messages", action="create", conditions=dict(method=["POST"])) map.connect("messages", "/messages", controller="messages", action="index", conditions=dict(method=["GET"])) map.connect("formatted_messages", "/messages.{format}", controller="messages", action="index", conditions=dict(method=["GET"])) map.connect("new_message", "/messages/new", controller="messages", action="new", conditions=dict(method=["GET"])) map.connect("formatted_new_message", "/messages/new.{format}", controller="messages", action="new", conditions=dict(method=["GET"])) map.connect("/messages/{id}", controller="messages", action="update", conditions=dict(method=["PUT"])) map.connect("/messages/{id}", controller="messages", action="delete", conditions=dict(method=["DELETE"])) map.connect("edit_message", "/messages/{id}/edit", controller="messages", action="edit", conditions=dict(method=["GET"])) map.connect("formatted_edit_message", "/messages/{id}.{format}/edit", controller="messages", action="edit", conditions=dict(method=["GET"])) map.connect("message", "/messages/{id}", controller="messages", action="show", conditions=dict(method=["GET"])) map.connect("formatted_message", "/messages/{id}.{format}", controller="messages", action="show", conditions=dict(method=["GET"])) This establishes the following convention:: GET /messages => messages.index() => url("messages") POST /messages => messages.create() => url("messages") GET /messages/new => messages.new() => url("new_message") PUT /messages/1 => messages.update(id) => url("message", id=1) DELETE /messages/1 => messages.delete(id) => url("message", id=1) GET /messages/1 => messages.show(id) => url("message", id=1) GET /messages/1/edit => messages.edit(id) => url("edit_message", id=1) .. note:: Due to how Routes matches a list of URL's, it has no inherent knowledge of a route being a **resource**. As such, if a route fails to match due to the method requirements not being met, a 404 will return just like any other failure to match a route. Thus, you GET the collection to see an index of links to members ("index" method). You GET a member to see it ("show"). You GET "COLLECTION/new" to obtain a new message form ("new"), which you POST to the collection ("create"). You GET "MEMBER/edit" to obtain an edit for ("edit"), which you PUT to the member ("update"). You DELETE the member to delete it. Note that there are only four route names because multiple actions are doubled up on the same URLs. This URL structure may look strange if you're not used to the Atom protocol. REST is a vague term, and some people think it means proper URL syntax (every component contains the one on its right), others think it means not putting IDs in query parameters, and others think it means using HTTP methods beyond GET and POST. ``map.resource`` does all three, but it may be overkill for applications that don't need Atom compliance or prefer to stick with GET and POST. ``map.resource`` has the advantage that many automated tools and non-browser agents will be able to list and modify your resources without any programming on your part. But you don't have to use it if you prefer a simpler add/modify/delete structure. HTML forms can produce only GET and POST requests. As a workaround, if a POST request contains a ``_method`` parameter, the Routes middleware changes the HTTP method to whatever the parameter specifies, as if it had been requested that way in the first place. This convention is becoming increasingly common in other frameworks. If you're using WebHelpers, the The WebHelpers ``form`` function has a ``method`` argument which automatically sets the HTTP method and "_method" parameter. Several routes are paired with an identical route containing the ``format`` variable. The intention is to allow users to obtain different formats by means of filename suffixes; e.g., "/messages/1.xml". This produces a routing variable "xml", which in Pylons will be passed to the controller action if it defines a formal argument for it. In generation you can pass the ``format`` argument to produce a URL with that suffix:: url("message", id=1, format="xml") => "/messages/1.xml" Routes does not recognize any particular formats or know which ones are valid for your application. It merely passes the ``format`` attribute through if it appears. New in Routes 1.7.3: changed URL suffix from ";edit" to "/edit". Semicolons are not allowed in the path portion of a URL except to delimit path parameters, which nobody uses. Resource options ---------------- The ``map.resource`` method recognizes a number of keyword args which modifies its behavior: controller Use the specified controller rather than deducing it from the collection name. collection Additional URLs to allow for the collection. Example:: map.resource("message", "messages", collection={"rss": "GET"}) # "GET /message/rss" => ``Messages.rss()``. # Defines a named route "rss_messages". member Additional URLs to allow for a member. Example:: map.resource('message', 'messages', member={'mark':'POST'}) # "POST /message/1/mark" => ``Messages.mark(1)`` # also adds named route "mark_message" This can be used to display a delete confirmation form:: map.resource("message", "messages", member={"ask_delete": "GET"} # "GET /message/1/ask_delete" => ``Messages.ask_delete(1)``. # Also adds a named route "ask_delete_message". new Additional URLs to allow for new-member functionality. :: map.resource("message", "messages", new={"preview": "POST"}) # "POST /messages/new/preview" path_prefix Prepend the specified prefix to all URL patterns. The prefix may include path variables. This is mainly used to nest resources within resources. name_prefix Prefix the specified string to all route names. This is most often combined with ``path_prefix`` to nest resources:: map.resource("message", "messages", controller="categories", path_prefix="/category/{category_id}", name_prefix="category_") # GET /category/7/message/1 # Adds named route "category_message" parent_resource A dict containing information about the parent resource, for creating a nested resource. It should contain the member_name and collection_name of the parent resource. This dict will be available via the associated Route object which can be accessed during a request via ``request.environ["routes.route"]``. If parent_resource is supplied and path_prefix isn't, path_prefix will be generated from parent_resource as "/:_id". If parent_resource is supplied and name_prefix isn't, name_prefix will be generated from parent_resource as "_". Example:: >>> m = Mapper() >>> m.resource('location', 'locations', ... parent_resource=dict(member_name='region', ... collection_name='regions')) >>> # path_prefix is "regions/:region_id" >>> # name prefix is "region_" >>> url('region_locations', region_id=13) '/regions/13/locations' >>> url('region_new_location', region_id=13) '/regions/13/locations/new' >>> url('region_location', region_id=13, id=60) '/regions/13/locations/60' >>> url('region_edit_location', region_id=13, id=60) '/regions/13/locations/60/edit' Overriding generated path_prefix: >>> m = Mapper() >>> m.resource('location', 'locations', ... parent_resource=dict(member_name='region', ... collection_name='regions'), ... path_prefix='areas/:area_id') >>> # name prefix is "region_" >>> url('region_locations', area_id=51) '/areas/51/locations' Overriding generated name_prefix: >>> m = Mapper() >>> m.resource('location', 'locations', ... parent_resource=dict(member_name='region', ... collection_name='regions'), ... name_prefix='') >>> # path_prefix is "regions/:region_id" >>> url('locations', region_id=51) '/regions/51/locations' Routes-2.3.1/docs/generating.rst0000644000175000017500000001763712553617302016157 0ustar benben00000000000000Generation ========== To generate URLs, use the ``url`` or ``url_for`` object provided by your framework. ``url`` is an instance of Routes ``URLGenerator``, while ``url_for`` is the older ``routes.url_for()`` function. ``url_for`` is being phased out, so new applications should use ``url``. To generate a named route, specify the route name as a positional argument:: url("home") => "/" If the route contains path variables, you must specify values for them using keyword arguments:: url("blog", year=2008, month=10, day=2) Non-string values are automatically converted to strings using ``str()``. (This may break with Unicode values containing non-ASCII characters.) However, if the route defines an extra variable with the same name as a path variable, the extra variable is used as the default if that keyword is not specified. Example:: m.connect("archives", "/archives/{id}", controller="archives", action="view", id=1) url("archives", id=123) => "/archives/123" url("archives") => "/archives/1" (The extra variable is *not* used for matching unless minimization is enabled.) Any keyword args that do not correspond to path variables will be put in the query string. Append a "_" if the variable name collides with a Python keyword:: map.connect("archive", "/archive/{year}") url("archive", year=2009, font=large) => "/archive/2009?font=large" url("archive", year=2009, print_=1) => "/archive/2009?print=1" If the application is mounted at a subdirectory of the URL space, all generated URLs will have the application prefix. The application prefix is the "SCRIPT_NAME" variable in the request's WSGI environment. If the positional argument corresponds to no named route, it is assumed to be a literal URL. The application's mount point is prefixed to it, and keyword args are converted to query parameters:: url("/search", q="My question") => "/search?q=My+question" If there is no positional argument, Routes will use the keyword args to choose a route. The first route that has all path variables specified by keyword args and the fewest number of extra variables not overridden by keyword args will be chosen. This was common in older versions of Routes but can cause application bugs if an unexpected route is chosen, so using route names is much preferable because that guarantees only the named route will be chosen. The most common use for unnamed generation is when you have a seldom-used controller with a lot of ad hoc methods; e.g., ``url(controller="admin", action="session")``. An exception is raised if no route corresponds to the arguments. The exception is ``routes.util.GenerationException``. (Prior to Routes 1.9, ``None`` was returned instead. It was changed to an exception to prevent invalid blank URLs from being insered into templates.) You'll also get this exception if Python produces a Unicode URL (which could happen if the route path or a variable value is Unicode). Routes generates only ``str`` URLs. The following keyword args are special: anchor Specifies the URL anchor (the part to the right of "#"). :: url("home", "summary") => "/#summary" host Make the URL fully qualified and override the host (domain). protocol Make the URL fully qualified and override the protocol (e.g., "ftp"). qualified Make the URL fully qualified (i.e., add "protocol://host:port" prefix). sub_domain See "Generating URLs with subdomains" below. The syntax in this section is the same for both ``url`` and ``url_for``. *New in Routes 1.10: ``url`` and the ``URLGenerator`` class behind it.* Generating routes based on the current URL ------------------------------------------ ``url.current()`` returns the URL of the current request, without the query string. This is called "route memory", and works only if the RoutesMiddleware is in the middleware stack. Keyword arguments override path variables or are put on the query string. ``url_for`` combines the behavior of ``url`` and ``url_current``. This is deprecated because nameless routes and route memory have the same syntax, which can lead to the wrong route being chosen in some cases. Here's an example of route memory:: m.connect("/archives/{year}/{month}/{day}", year=2004) # Current URL is "/archives/2005/10/4". # Routing variables are {"controller": "archives", "action": "view", "year": "2005", "month": "10", "day": "4"} url.current(day=6) => "/archives/2005/10/6" url.current(month=4) => "/archives/2005/4/4" url.current() => "/archives/2005/10/4" Route memory can be disabled globally with ``map.explicit = True``. Generation-only routes (aka. static routes) ------------------------------------------- A static route is used only for generation -- not matching -- and it must be named. To define a static route, use the argument ``_static=True``. This example provides a convenient way to link to a search:: map.connect("google", "http://google.com/", _static=True) url("google", q="search term") => "http://google.com/?q=search+term") This example generates a URL to a static image in a Pylons public directory. Pylons serves the public directory in a way that bypasses Routes, so there's no reason to match URLs under it. :: map.connect("attachment", "/images/attachments/{category}/{id}.jpg", _static=True) url("attachment", category="dogs", id="Mastiff") => "/images/attachments/dogs/Mastiff.jpg" Starting in Routes 1.10, static routes are exactly the same as regular routes except they're not added to the internal match table. In previous versions of Routes they could not contain path variables and they had to point to external URLs. Filter functions ---------------- A filter function modifies how a named route is generated. Don't confuse it with a function condition, which is used in matching. A filter function is its opposite counterpart. One use case is when you have a ``story`` object with attributes for year, month, and day. You don't want to hardcode these attributes in every ``url`` call because the interface may change someday. Instead you pass the story as a pseudo-argument, and the filter produces the actual generation args. Here's an example:: class Story(object): def __init__(self, year, month, day): self.year = year self.month = month self.day = day @staticmethod def expand(kw): try: story = kw["story"] except KeyError: pass # Don't modify dict if ``story`` key not present. else: # Set the actual generation args from the story. kw["year"] = story.year kw["month"] = story.month kw["day"] = story.day return kw m.connect("archives", "/archives/{year}/{month}/{day}", controller="archives", action="view", _filter=Story.expand) my_story = Story(2009, 1, 2) url("archives", story=my_story) => "/archives/2009/1/2" The ``_filter`` argument can be any function that takes a dict and returns a dict. In the example we've used a static method of the ``Story`` class to keep everything story-related together, but you may prefer to use a standalone function to keep Routes-related code away from your model. Generating URLs with subdomains ------------------------------- If subdomain support is enabled and the ``sub_domain`` arg is passed to ``url_for``, Routes ensures the generated route points to that subdomain. :: # Enable subdomain support. map.sub_domains = True # Ignore the www subdomain. map.sub_domains_ignore = "www" map.connect("/users/{action}") # Add a subdomain. url_for(action="update", sub_domain="fred") => "http://fred.example.com/users/update" # Delete a subdomain. Assume current URL is fred.example.com. url_for(action="new", sub_domain=None) => "http://example.com/users/new" Routes-2.3.1/docs/modules/0000755000175000017500000000000012676765171014752 5ustar benben00000000000000Routes-2.3.1/docs/modules/route.rst0000644000175000017500000000026112456520011016613 0ustar benben00000000000000:mod:`routes.route` -- Route ============================ .. automodule:: routes.route Module Contents --------------- .. autoclass:: Route :members: :undoc-members: Routes-2.3.1/docs/modules/mapper.rst0000644000175000017500000000047512456520011016750 0ustar benben00000000000000:mod:`routes.mapper` -- Mapper and Sub-Mapper ============================================= .. automodule:: routes.mapper Module Contents --------------- .. autoclass:: SubMapperParent :members: :undoc-members: .. autoclass:: SubMapper :members: :undoc-members: .. autoclass:: Mapper :members: Routes-2.3.1/docs/modules/index.rst0000644000175000017500000000021512456526575016610 0ustar benben00000000000000.. _modules: ============== Routes Modules ============== .. toctree:: :maxdepth: 2 routes mapper route middleware util Routes-2.3.1/docs/modules/util.rst0000644000175000017500000000076412456520011016442 0ustar benben00000000000000:mod:`routes.util` -- URL Generator and utility functions ========================================================= .. automodule:: routes.util Module Contents --------------- .. autoexception:: RoutesException .. autoexception:: MatchException .. autoexception:: GenerationException .. autoclass:: URLGenerator :members: :undoc-members: .. autofunction:: url_for .. autofunction:: _url_quote .. autofunction:: _str_encode .. autofunction:: _screenargs .. autofunction:: _subdomain_check Routes-2.3.1/docs/modules/routes.rst0000644000175000017500000000040512456520011016776 0ustar benben00000000000000:mod:`routes` -- Routes Common Classes and Functions ==================================================== .. automodule:: routes Module Contents --------------- .. autofunction:: request_config .. autoclass:: _RequestConfig :members: :undoc-members: Routes-2.3.1/docs/modules/middleware.rst0000644000175000017500000000041412676247625017617 0ustar benben00000000000000:mod:`routes.middleware` -- Routes WSGI Middleware ================================================== .. automodule:: routes.middleware Module Contents --------------- .. autoclass:: RoutesMiddleware :members: :undoc-members: .. autofunction:: is_form_post Routes-2.3.1/docs/porting.rst0000644000175000017500000001011612553617302015477 0ustar benben00000000000000Porting Routes to a WSGI Web Framework %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% RoutesMiddleware ---------------- An application can create a raw mapper object and call its ``.match`` and ``.generate`` methods. However, WSGI applications probably want to use the ``RoutesMiddleware`` as Pylons does:: # In myapp/config/middleware.py from routes.middleware import RoutesMiddleware app = RoutesMiddleware(app, map) # ``map`` is a routes.Mapper. The middleware matches the requested URL and sets the following WSGI variables:: environ['wsgiorg.routing_args'] = ((url, match)) environ['routes.route'] = route environ['routes.url'] = url where ``match`` is the routing variables dict, ``route`` is the matched route, and ``url`` is a ``URLGenerator`` object. In Pylons, ``match`` is used by the dispatcher, and ``url`` is accessible as ``pylons.url``. The middleware handles redirect routes itself, issuing the appropriate redirect. The application is not called in this case. To debug routes, turn on debug logging for the "routes.middleware" logger. See the Routes source code for other features which may have been added. URL Resolution -------------- When the URL is looked up, it should be matched against the Mapper. When matching an incoming URL, it is assumed that the URL path is the only string being matched. All query args should be stripped before matching:: m.connect('/articles/{year}/{month}', controller='blog', action='view', year=None) m.match('/articles/2003/10') # {'controller':'blog', 'action':'view', 'year':'2003', 'month':'10'} Matching a URL will return a dict of the match results, if you'd like to differentiate between where the argument came from you can use routematch which will return the Route object that has all these details:: m.connect('/articles/{year}/{month}', controller='blog', action='view', year=None) result = m.routematch('/articles/2003/10') # result is a tuple of the match dict and the Route object # result[0] - {'controller':'blog', 'action':'view', 'year':'2003', 'month':'10'} # result[1] - Route object # result[1].defaults - {'controller':'blog', 'action':'view', 'year':None} # result[1].hardcoded - ['controller', 'action'] Your integration code is then expected to dispatch to a controller and action in the dict. How it does this is entirely up to the framework integrator. Your integration should also typically provide the web developer a mechanism to access the additional dict values. Request Configuration --------------------- If you intend to support ``url_for()`` and ``redirect_to()``, they depend on a singleton object which requires additional configuration. You're better off not supporting them at all because they will be deprecated soon. ``URLGenerator`` is the forward-compatible successor to ``url_for()``. ``redirect_to()`` is better done in the web framework`as in ``pylons.controllers.util.redirect_to()``. ``url_for()`` and ``redirect_to()`` need information on the current request, and since they can be called from anywhere they don't have direct access to the WSGI environment. To remedy this, Routes provides a thread-safe singleton class called "request_config", which holds the request information for the current thread. You should update this after matching the incoming URL but before executing any code that might call the two functions. Here is an example:: from routes import request_config config = request_config() config.mapper = m # Your mapper object config.mapper_dict = result # The dict from m.match for this URL request config.host = hostname # The server hostname config.protocol = port # Protocol used, http, https, etc. config.redirect = redir_func # A redirect function used by your framework, that is # expected to take as the first non-keyword arg a single # full or relative URL See the docstring for ``request_config`` in routes/__init__.py to make sure you've initialized everything necessary. Routes-2.3.1/docs/introduction.rst0000644000175000017500000000432012553617302016536 0ustar benben00000000000000Introduction ============ Routes tackles an interesting problem that comes up frequently in web development, *how do you map URLs to your application's actions*? That is, how do you say that *this* should be accessed as "/blog/2008/01/08", and "/login" should do *that*? Many web frameworks have a fixed dispatching system; e.g., "/A/B/C" means to read file "C" in directory "B", or to call method "C" of class "B" in module "A.B". These work fine until you need to refactor your code and realize that moving a method changes its public URL and invalidates users' bookmarks. Likewise, if you want to reorganize your URLs and make a section into a subsection, you have to change your carefully-tested logic code. Routes takes a different approach. You determine your URL hierarchy and actions separately, and then link them together in whichever ways you decide. If you change your mind about a particular URL, just change one line in your route map and never touch your action logic. You can even have multiple URLs pointing to the same action; e.g., to support legacy bookmarks. Routes was originally inspired by the dispatcher in Ruby on Rails but has since diverged. Routes is the primary dispatching system in the Pylons web framework, and an optional choice in CherryPy. It can be added to any framework without much fuss, and used for an entire site or a URL subtree. It can also forward subtrees to other dispatching systems, which is how TurboGears 2 is implemented on top of Pylons. Current features: * Sophisticated route lookup and URL generation * Named routes * Redirect routes * Wildcard paths before and after static parts * Sub-domain support built-in * Conditional matching based on domain, cookies, HTTP method (RESTful), and more * Easily extensible utilizing custom condition functions and route generation functions * Extensive unit tests Buzzword compliance: REST, DRY. If you're new to Routes or have not read the Routes 1.11 manual before, we recommend reading the `Glossary `_ before continuing. This manual is written from the user's perspective: how to use Routes in a framework that already supports it. The `Porting `_ manual describes how to add Routes support to a new framework. Routes-2.3.1/docs/uni_redirect_rest.rst0000644000175000017500000002054012456565017017537 0ustar benben00000000000000============================ Unicode, Redirects, and More ============================ Unicode ======= Routes assumes UTF-8 encoding on incoming URLs, and ``url`` and ``url_for`` also generate UTF-8. You can change the encoding with the ``map.charset`` attribute:: map.charset = "latin-1" New in Routes 1.10: several bugfixes. Redirect Routes =============== Redirect routes allow you to specify redirects in the route map, similar to RewriteRule in an Apache configuration. This avoids the need to define dummy controller actions just to handle redirects. It's especially useful when the URL structure changes and you want to redirect legacy URLs to their new equivalents. The redirection is done by the Routes middleware, and the WSGI application is not called. ``map.redirect`` takes two positional arguments: the route path and the destination URL. Redirect routes do not have a name. Both paths can contain variables, and the route path can take inline requirements. Keyword arguments are the same as ``map.connect``, both in regards to extra variables and to route options. :: map.redirect("/legacyapp/archives/{url:.*}", "/archives/{url}") map.redirect("/legacyapp/archives/{url:.*}", "/archives/{url}") By default a "302 Found" HTTP status is issued. You can override this with the ``_redirect_code`` keyword argument. The value must be an entire status string. :: map.redirect("/home/index", "/", _redirect_code="301 Moved Permanently") *New in Routes 1.10.* Printing ======== Mappers now have a formatted string representation. In your python shell, simply print your application's mapper:: >>> map.collection("entries", "entry") >>> print map Route name Methods Path Controller action entries GET /entries{.format} entry index create_entry POST /entries{.format} entry create new_entry GET /entries/new{.format} entry new entry GET /entries/{id}{.format} entry show update_entry PUT /entries/{id}{.format} entry update delete_entry DELETE /entries/{id}{.format} entry delete edit_entry GET /entries/{id}/edit{.format} entry edit *New in Routes 1.12.* *Controller/action fields new in Routes 2.1* Introspection ============= The mapper attribute ``.matchlist`` contains the list of routes to be matched against incoming URLs. You can iterate this list to see what routes are defined. This can be useful when debugging route configurations. Other ===== If your application is behind an HTTP proxy such a load balancer on another host, the WSGI environment will refer to the internal server rather than to the proxy, which will mess up generated URLs. Use the ProxyMiddleware in PasteDeploy to fix the WSGI environment to what it would have been without the proxy. To debug routes, turn on debug logging for the "routes.middleware" logger. (See Python's ``logging`` module to set up your logging configuration.) Backward compatibility ====================== The following syntaxes are allowed for compatibility with previous versions of Routes. They may be removed in the future. Omitting the name arg --------------------- In the tutorial we said that nameless routes can be defined by passing ``None`` as the first argument. You can also omit the first argument entirely:: map.connect(None, "/{controller}/{action}") map.connect("/{controller}/{action}") The syntax with ``None`` is preferred to be forward-compatible with future versions of Routes. It avoids the path argument changing position between the first and second arguments, which is unpythonic. :varname -------- Path variables were defined in the format ``:varname`` and ``:(varname)`` prior to Routes 1.9. The form with parentheses was called "grouping", used to delimit the variable name from a following letter or number. Thus the old syntax "/:controller/:(id)abc" corresponds to the new syntax "/{controller}/{id}abc". The older wildcard syntax is ``*varname`` or ``*(varname)``:: # OK because the following component is static. map.connect("/static/*filename/download") # Deprecated syntax. WRONG because the wildcard will eat the rest of the # URL, leaving nothing for the following variable, which will cause the # match to fail. map.connect("/static/*filename/:action") Minimization ------------ Minimization was a misfeature which was intended to save typing, but which often resulted in the wrong route being chosen. Old applications that still depend on it must now enable it by putting ``map.minimization = True`` in their route definitions. Without minimization, the URL must contain values for all path variables in the route:: map.connect("basic", "/{controller}/{action}", controller="mycontroller", action="myaction", weather="sunny") This route matches any two-component URL, for instance "/help/about". The resulting routing variables would be:: {"controller": "help", "action": "about", "weather": "sunny"} The path variables are taken from the URL, and any extra variables are added as constants. The extra variables for "controller" and "action" are *never used* in matching, but are available as default values for generation:: url("basic", controller="help") => "/help/about?weather=sunny" With minimization, the same route path would also match shorter URLs such as "/help", "/foo", and "/". Missing values on the right of the URL would be taken from the extra variables. This was intended to lessen the number of routes you had to write. In practice it led to obscure application bugs because sometimes an unexpected route would be matched. Thus Routes 1.9 introduced non-minimization and recommended "map.minimization = False" for all new applications. A corollary problem was generating the wrong route. Routes 1.9 tightened up the rule for generating named routes. If a route name is specified in ``url()`` or ``url_for()``, *only* that named route will be chosen. In previous versions, it might choose another route based on the keyword args. Implicit defaults and route memory ---------------------------------- Implicit defaults worked with minimization to provide automatic default values for the "action" and "id" variables. If a route was defined as ``map.connect("/{controller}/{action}/{id}") and the URL "/archives"`` was requested, Routes would implicitly add ``action="index", id=None`` to the routing variables. To enable implicit defaults, set ``map.minimization = True; map.explicit = False``. You can also enable implicit defaults on a per-route basis by setting ``map.explicit = True`` and defining each route with a keyword argument ``explicit=False``. Previous versions also had implicit default values for "controller", "action", and "id". These are now disabled by default, but can be enabled via ``map.explicit = True``. This also enables route memory url_for() --------- ``url_for`` was a route generation function which was replaced by the ``url`` object. Usage is the same except that ``url_for`` uses route memory in some cases and ``url`` never does. Route memory is where variables from the current URL (the current request) are injected into the generated URL. To use route memory with ``url``, call ``url.current()`` passing the variables you want to override. Any other variables needed by the route will be taken from the current routing variables. In other words, ``url_for`` combines ``url`` and ``url.current()`` into one function. The location of ``url_for`` is also different. ``url_for`` is properly imported from ``routes``:: from routes import url_for ``url_for`` was traditionally imported into WebHelpers, and it's still used in some tests and in ``webhelpers.paginate``. Many old Pylons applications contain ``h.url_for()`` based on its traditional importation to helpers.py. However, its use in new applications is discouraged both because of its ambiguous syntax and because its implementation depends on an ugly singleton. The ``url`` object is created by the RoutesMiddleware and inserted into the WSGI environment. Pylons makes it available as ``pylons.url``, and in templates as ``url``. redirect_to() ------------- This combined ``url_for`` with a redirect. Instead, please use your framework's redirect mechanism with a ``url`` call. For instance in Pylons:: from pylons.controllers.util import redirect redirect(url("login")) Routes-2.3.1/docs/Makefile0000644000175000017500000000422212456520011014714 0ustar benben00000000000000# Makefile for Sphinx documentation # # You can set these variables from the command line.

Routes makes it easy to create pretty and concise URLs that are RESTful with little effort. Routes allows conditional matching based on domain, cookies, HTTP method, or a custom function. Sub-domain support is built in. Routes comes with an extensive unit test suite. Current features: * Sophisticated route lookup and URL generation * Named routes * Redirect routes * Wildcard paths before and after static parts * Sub-domain support built-in * Conditional matching based on domain, cookies, HTTP method (RESTful), and more * Easily extensible utilizing custom condition functions and route generation functions * Extensive unit tests Installing ========== Routes can be easily installed with pip or easy_install:: $ easy_install routes Example ======= .. code-block:: python # Setup a mapper from routes import Mapper map = Mapper() map.connect(None, "/error/{action}/{id}", controller="error") map.connect("home", "/", controller="main", action="index") # Match a URL, returns a dict or None if no match result = map.match('/error/myapp/4') # result == {'controller': 'error', 'action': 'myapp', 'id': '4'} Source ====== The `routes source can be found on GitHub `_. Bugs/Support ============ Bug's can be reported on the `github issue tracker `_. Note that routes is in maintenance mode so bug reports are unlikely to be worked on, pull requests will be applied if submitted with tests.

The URL "/help/about" contains two components: "help" and "about". generation The act of creating a URL based on a route name and/or variable values. This is the opposite of matching. Finding a route by name is called *named generation*. Finding a route without specifying a name is called *nameless generation*. mapper A container for routes. There is normally one mapper per application, although nested subapplications might have their own mappers. A mapper knows how to match routes and generate them. matching The act of matching a given URL against a list of routes, and returning the routing variables. See the *route* entry for an example. minimization A deprecated feature which allowed short URLs to match long paths. Details are in the ``Backward Compatibility`` section in the manual. route A rule mapping a URL pattern to a dict of routing variables. For instance, if the pattern is "/{controller}/{action}" and the requested URL is "/help/about", the resulting dict would be:: {"controller": "help", "action": "about"} Routes does not know what these variables mean; it simply returns them to the application. Pylons would look for a ``controllers/help.py`` module containing a ``HelpController`` class, and call its ``about`` method. Other frameworks may do something different. A route may have a name, used to identify the route. route path The URL pattern in a route. routing variables A dict of key-value pairs returned by matching. Variables defined in the route path are called *path variables*; their values will be taken from the URL. Variables defined outside the route path are called *default variables*; their values are not affected by the URL. The WSGI.org environment key for routing variables is "wsgiorg.routing_args". This manual does not use that term because it can be confused with function arguments.

In Pylons, you define your routes in the ``make_map`` function in your *myapp/config/routing.py* module. Here is a typical configuration: .. code-block:: python :linenos: from routes import Mapper map = Mapper() map.connect(None, "/error/{action}/{id}", controller="error") map.connect("home", "/", controller="main", action="index") # ADD CUSTOM ROUTES HERE map.connect(None, "/{controller}/{action}") map.connect(None, "/{controller}/{action}/{id}") Lines 1 and 2 create a mapper. Line 3 matches any three-component route that starts with "/error", and sets the "controller" variable to a constant, so that a URL "/error/images/arrow.jpg" would produce:: {"controller": "error", "action": "images", "id": "arrow.jpg"} Line 4 matches the single URL "/", and sets both the controller and action to constants. It also has a route name "home", which can be used in generation. (The other routes have ``None`` instead of a name, so they don't have names. It's recommended to name all routes that may be used in generation, but it's not necessary to name other routes.) Line 6 matches any two-component URL, and line 7 matches any 3-component URL. These are used as catchall routes if we're too lazy to define a separate route for every action. If you *have* defined a route for every action, you can delete these two routes. Note that a URL "/error/images/arrow.jpg" could match both line 3 and line 7. The mapper resolves this by trying routes in the order defined, so this URL would match line 3. If no routes match the URL, the mapper returns a "match failed" condition, which is seen in Pylons as HTTP 404 "Not Found". Here are some more examples of valid routes:: m.connect("/feeds/{category}/atom.xml", controller="feeds", action="atom") m.connect("history", "/archives/by_eon/{century}", controller="archives", action="aggregate") m.connect("article", "/article/{section}/{slug}/{page}.html", controller="article", action="view") Extra variables may be any Python type, not just strings. However, if the route is used in generation, ``str()`` will be called on the value unless the generation call specifies an overriding value. Other argument syntaxes are allowed for compatibility with earlier versions of Routes. These are described in the ``Backward Compatibility`` section. Route paths should always begin with a slash ("/"). Earlier versions of Routes allowed slashless paths, but their behavior now is undefined. Requirements ------------ It's possible to restrict a path variable to a regular expression; e.g., to match only a numeric component or a restricted choice of words. There are two syntaxes for this: inline and the ``requirements`` argument. An inline requirement looks like this:: map.connect(R"/blog/{id:\d+}") map.connect(R"/download/{platform:windows|mac}/{filename}") This matches "/blog/123" but not "/blog/12A". The equivalent ``requirements`` syntax is:: map.connect("/blog/{id}", requirements={"id": R"\d+"} map.connect("/download/{platform}/{filename}", requirements={"platform": R"windows|mac"}) Note the use of raw string syntax (``R""``) for regexes which might contain backslashes. Without the R you'd have to double every backslash. Another example:: m.connect("/archives/{year}/{month}/{day}", controller="archives", action="view", year=2004, requirements=dict(year=R"\d{2,4}", month=R"\d{1,2}")) The inline syntax was added in Routes (XXX 1.10?? not in changelog). Previous versions had only the ``requirements`` argument. Two advantages of the ``requirements`` argument are that if you have several variables with identical requirements, you can set one variable or even the entire argument to a global:: NUMERIC = R"\d+" map.connect(..., requirements={"id": NUMERIC}) ARTICLE_REQS = {"year": R"\d\d\d\d", "month": R"\d\d", "day": R"\d\d"} map.connect(..., requirements=ARTICLE_REQS) Because the argument ``requirements`` is reserved, you can't define a routing variable by that name. Magic path_info --------------- If the "path_info" variable is used at the end of the URL, Routes moves everything preceding it into the "SCRIPT_NAME" environment variable. This is useful when delegating to another WSGI application that does its own routing: the subapplication will route on the remainder of the URL rather than the entire URL. You still need the ":.*" requirement to capture the following URL components into the variable. :: map.connect(None, "/cards/{path_info:.*}", controller="main", action="cards") # Incoming URL "/cards/diamonds/4.png" => {"controller": "main", action: "cards", "path_info": "/diamonds/4.png"} # Second WSGI application sees: # SCRIPT_NAME="/cards" PATH_INFO="/diamonds/4.png" This route does not match "/cards" because it requires a following slash. Add another route to get around this:: map.connect("cards", "/cards", controller="main", action="cards", path_info="/") .. tip:: You may think you can combine the two with the following route:: map.connect("cards", "/cards{path_info:.*}", controller="main", action="cards") There are two problems with this, however. One, it would also match "/cardshark". Two, Routes 1.10 has a bug: it forgets to take the suffix off the SCRIPT_NAME. A future version of Routes may delegate directly to WSGI applications, but for now this must be done in the framework. In Pylons, you can do this in a controller action as follows:: from paste.fileapp import DirectoryApp def cards(self, environ, start_response): app = DirectoryApp("/cards-directory") return app(environ, start_response) Or create a fake controller module with a ``__controller__`` variable set to the WSGI application:: from paste.fileapp import DirectoryApp __controller__ = DirectoryApp("/cards-directory") Conditions ---------- Conditions impose additional constraints on what kinds of requests can match. The ``conditions`` argument is a dict with up to three keys: method A list of uppercase HTTP methods. The request must be one of the listed methods. sub_domain Can be a list of subdomains, ``True``, ``False``, or ``None``. If a list, the request must be for one of the specified subdomains. If ``True``, the request must contain a subdomain but it can be anything. If ``False`` or ``None``, do not match if there's a subdomain. *New in Routes 1.10: ``False`` and ``None`` values.* function A function that evaluates the request. Its signature must be ``func(environ, match_dict) => bool``. It should return true if the match is successful or false otherwise. The first arg is the WSGI environment; the second is the routing variables that would be returned if the match succeeds. The function can modify ``match_dict`` in place to affect which variables are returned. This allows a wide range of transformations. Examples:: # Match only if the HTTP method is "GET" or "HEAD". m.connect("/user/list", controller="user", action="list", conditions=dict(method=["GET", "HEAD"])) # A sub-domain should be present. m.connect("/", controller="user", action="home", conditions=dict(sub_domain=True)) # Sub-domain should be either "fred" or "george". m.connect("/", controller="user", action="home", conditions=dict(sub_domain=["fred", "george"])) # Put the referrer into the resulting match dictionary. # This function always returns true, so it never prevents the match # from succeeding. def referals(environ, result): result["referer"] = environ.get("HTTP_REFERER") return True m.connect("/{controller}/{action}/{id}", conditions=dict(function=referals)) Wildcard routes --------------- By default, path variables do not match a slash. This ensures that each variable will match exactly one component. You can use requirements to override this:: map.connect("/static/{filename:.*?}") This matches "/static/foo.jpg", "/static/bar/foo.jpg", etc. Beware that careless regexes may eat the entire rest of the URL and cause components to the right of it not to match:: # OK because the following component is static and the regex has a "?". map.connect("/static/{filename:.*?}/download") The lesson is to always test wildcard patterns. Format extensions ----------------- A path component of ``{.format}`` will match an optional format extension (e.g. ".html" or ".json"), setting the format variable to the part after the "." (e.g. "html" or "json") if there is one, or to ``None`` otherwise. For example:: map.connect('/entries/{id}{.format}') will match "/entries/1" and "/entries/1.mp3". You can use requirements to limit which extensions will match, for example:: map.connect('/entries/{id:\d+}{.format:json}') will match "/entries/1" and "/entries/1.json" but not "/entries/1.mp3". As with wildcard routes, it's important to understand and test this. Without the ``\d+`` requirement on the ``id`` variable above, "/entries/1.mp3" would match successfully, with the ``id`` variable capturing "1.mp3". *New in Routes 1.12.* Submappers ---------- A submapper lets you add several similar routes without having to repeat identical keyword arguments. There are two syntaxes, one using a Python ``with`` block, and the other avoiding it. :: # Using 'with' with map.submapper(controller="home") as m: m.connect("home", "/", action="splash") m.connect("index", "/index", action="index") # Not using 'with' m = map.submapper(controller="home") m.connect("home", "/", action="splash") m.connect("index", "/index", action="index") # Both of these syntaxes create the following routes:: # "/" => {"controller": "home", action="splash"} # "/index" => {"controller": "home", action="index"} You can also specify a common path prefix for your routes:: with map.submapper(path_prefix="/admin", controller="admin") as m: m.connect("admin_users", "/users", action="users") m.connect("admin_databases", "/databases", action="databases") # /admin/users => {"controller": "admin", "action": "users"} # /admin/databases => {"controller": "admin", "action": "databases"} All arguments to ``.submapper`` must be keyword arguments. The submapper is *not* a complete mapper. It's just a temporary object with a ``.connect`` method that adds routes to the mapper it was spawned from. *New in Routes 1.11.* Submapper helpers ----------------- Submappers contain a number of helpers that further simplify routing configuration. This:: with map.submapper(controller="home") as m: m.connect("home", "/", action="splash") m.connect("index", "/index", action="index") can be written:: with map.submapper(controller="home", path_prefix="/") as m: m.action("home", action="splash") m.link("index") The ``action`` helper generates a route for one or more HTTP methods ('GET' is assumed) at the submapper's path ('/' in the example above). The ``link`` helper generates a route at a relative path. There are specific helpers corresponding to the standard ``index``, ``new``, ``create``, ``show``, ``edit``, ``update`` and ``delete`` actions. You can use these directly:: with map.submapper(controller="entries", path_prefix="/entries") as entries: entries.index() with entries.submapper(path_prefix="/{id}") as entry: entry.show() or indirectly:: with map.submapper(controller="entries", path_prefix="/entries", actions=["index"]) as entries: entries.submapper(path_prefix="/{id}", actions=["show"]) Collection/member submappers nested in this way are common enough that there is helper for this too:: map.collection(collection_name="entries", member_name="entry", controller="entries", collection_actions=["index"], member_actions["show"]) This returns a submapper instance to which further routes may be added; it has a ``member`` property (a nested submapper) to which which member-specific routes can be added. When ``collection_actions`` or ``member_actions`` are omitted, the full set of actions is generated (see the example under "Printing" below). See "RESTful services" below for ``map.resource``, a precursor to ``map.collection`` that does not use submappers. *New in Routes 1.12.* Adding routes from a nested application --------------------------------------- *New in Routes 1.11.* Sometimes in nested applications, the child application gives the parent a list of routes to add to its mapper. These can be added with the ``.extend`` method, optionally providing a path prefix:: from routes.route import Route routes = [ Route("index", "/index.html", controller="home", action="index"), ] map.extend(routes) # /index.html => {"controller": "home", "action": "index"} map.extend(routes, "/subapp") # /subapp/index.html => {"controller": "home", "action": "index"} This does not exactly add the route objects to the mapper. It creates identical new route objects and adds those to the mapper. *New in Routes 1.11.* Routes-2.3.1/docs/routes-logo.png0000644000175000017500000004240312456520011016244 0ustar benben00000000000000PNG  IHDRd\95sRGB pHYs B(xtIME $'J IDATxgxյkeF]drjz3 L͡%J!!^CHN'@ PBظ.mo{#HνIe?[߻^ko׷v}]߮o׿ѿ5'&\M5oƎcN{onvrom:K6&ƉY;s[W~x ]s >Nɟu1% օ=v! g35?Bp:',37& _UqC@&TnZ^G+(`j "xqsM=&F@O?Ȕ}[^ҁ!`~D*{a&r3ۭV@&>;Kb>,ݔt΁Ԙ xS]:g1+oXvwԪcbF#2E+K233rw c?|oU׶RSzi٦~r=ENv'lM0_cf&"bOL"1:hn/iW^hnNSO_>]F_L36ԲۭVTǀK ֵF zw#:j (@|"6 H缅#V,vg.ya6Yo>`p`Nd~oڎ㧖pgwѡt@Rir=jo(ޚ̡Wv= E<Λ/X@̺͉a41FM Dy92ar0!"a`nx[Z6]5X,=0Q}*cW׼7|ۙXg015MJ[z2ڰ_h~CX %?^QWpxGq~sԴ'XSSPzzY?$J< "0B82Ӧ"0s&D,Z,ba-^<{MGLKMkU適 oPL8SđcjԔ3(n5j|co(/(CE/֭H=+~&b  ~+_@$[4*J dzx1 >ԴQc~yR{]ͥaSuӭ7?68/ӅԸ PUl=zhҤ+W^O?cN y (1csl.pCZi-Ws\%d#Cا89\)Y*sA==ŧg2:~k:IWSw|[Z#~s_^Xz/Pr{ȃ{ʬ1h!DuФܼר+ yږrz.sO_J MW]wKs\_n<RLZSL?(+"G}tSa.D2D[RԖx\YHW2ꋒ#"y5aFݷc+27 .Wrܫ(pKjزrmo@y **u@"X퟽::A7&uu /%w@ڞ:5'3՝ghyG%£KeQ3 `;lWb `F2c!o{.bH04]MD&Q?JcA :>+jsZ33(3|`)#z2%%KB|Tbtv@id/Z'Ly5]{dnłe QGNg>[yp?

Patch by Davanum Srinivas (PR #65). Release 2.3 (March 28, 2016) ============================ * Fix sub_domain equivalence check. Patch by Nikita Uvarov * Add support for protocol-relative URLs generation (i.e. starting with double slash ``//``). PR #60. Patch by Sviatoslav Sydorenko. * Add support for the ``middleware`` extra requirement, making possible to depend on ``webob`` optionally. PR #59. Patch by Sviatoslav Sydorenko. * Fix matching of an empty string route, which led to exception in earlier versions. PR #58. Patch by Sviatoslav Sydorenko. * Add support for the ``requirements`` option when using mapper.resource to create routes. PR #57. Patch by Sean Dague. * Concatenation fix when using submappers with path prefixes. Multiple submappers combined the path prefix inside the controller argument in non-obvious ways. The controller argument will now be properly carried through when using submappers. PR #28. Release 2.2 (July 21, 2015) =========================== * Fix Python 3 support. Patch by Victor Stinner. Release 2.1 (January 17, 2015) ============================== * Fix 3 other route matching groups in route.py to use anonymous groups for optional sections to avoid exceeding regex limits. Fixes #15. * Printing a mapper now includes the Controller/action parameters from the route. Fixes #11. * Fix regression that didn't allow passing in params 'host', 'protocol', or 'anchor'. They can now be passed in with a trailing '_' as was possible before commit d1d1742903fa5ca24ef848a6ae895303f2661b2a. Fixes #7. * URL generation with/without SCRIPT_NAME was resulting in the URL cache failing to return the appropriate cached URL generation. The URL cache should always include the SCRIPT_NAME, even if its empty, in the cache to avoid this, and now does. Fixes #6. * Extract Route creation into separate method in Mapper. Subclasses of Route can be created by Mappers now. * Use the first X_FORWARDED_FOR value if there are multiple proxies in the path. Fixes #5. Release 2.0 (November 17, 2013) =============================== * Python 3.2/3.3 Support. Fixes Issue #2. Thanks to Alejandro Sánchez for the pull request! Release 1.13 (March 12, 2012) ============================= * Fix bug with dots forcing extension by default. The portion with the dot can now be recognized. Patch by Michael Basnight. Release 1.12.3 (June 5, 2010) ============================= * Fix bug with URLGenerator not properly including SCRIPT_NAME when generating URL's and the singleton is not present. Release 1.12.2 (May 5, 2010) ============================ * Fix bug with routes URLGenerator not properly including SCRIPT_NAME when generating qualified URL's. Release 1.12.1 (March 11, 2010) =============================== * Fix bug with routes not generating URL's with callables in defaults. * Fix bug with routes not handling sub-domain defaults during generation. Release 1.12 (February 28, 2010) ================================ * Split up the Routes docs. * Fix bug with relative URL's using qualified merging host and URL without including the appropriate slash. Fixes #13. * Fix bug with mapper.extend and Routes modifying their original args. Fixes #24. * Fix url.current() not returning current args when explicit is True. * Added explicit way to directly use the Mapper to match with environ. * Fix bug with improper len placement for submapper. * Adding regular expression builder for entire regexp for faster rejection in a single regexp match should none of the routes match. * Give Mapper a tabular string representation. * Make SubMapper objects nestable and add route-generation helpers. * Add SubMapper-based collections. * Make the deprecated Mapper.minimization False (disabled) by default. * Make the mapper explicit (true) by default. Release 1.11 (September 28, 2009) ================================= * Extensive documentation rewrite. * Added Mapper.extend function that allows one to add lists of Routes objects to the mapper in one batch, optionally with a path_prefix. * Added Mapper.submapper function that returns a SubMapper object to enable easier declaration of routes that have multiple keyword argument options in common. * Mapper controller_scan argument now handles None, and lists of controller names in addition to a callable. * Route object now takes a name parameter, which is the name it responds to. This name is automatically added when called by using Mapper's connect class method. * Added optional LRU object for use with Routes when URL's change too often for the Routes urlcache dict to be a viable option. Release 1.10.3 (February 8, 2009) ================================= * Tweak to use WebOb Request rather than Paste. * Performance tweaks for URL recognition. * Bugfix for routes.middleware not re.escaping the path_info before moving it to the script name. Release 1.10.2 (January 11, 2009) ================================= * Bugfix for unicode encoding problems with non-minimized Route generation. Spotted by Wichert Akkerman. * Bugfix for when environ is {} in unit tests. Release 1.10.1 (September 27, 2008) =================================== * Removing LRU cache due to performance and threading issues. Cache does hit a max-size for the given routes. Release 1.10 (September 24, 2008) ================================= * Adding LRU cache instead of just dict for caching generated routes. This avoids slow memory leakage over long-running and non-existent route generation. * Adding URLGenerator object. * Adding redirect routes. * Static routes can now interpolate variable parts in the path if using {} variable part syntax. * Added sub_domain condition option to accept False or None, to require that there be no sub-domain provided for the route to match. Release 1.9.2 (July 8, 2008) ============================ * Fixed bug in url_for which caused it to return a literal when it shouldn't have. Release 1.9.1 (June 28, 2008) ============================= * Fixed bug in formatted route recognition with formatting being absorbed into the id. Release 1.9 (June 12, 2008) =========================== * Fix undefined arg bug in url_for. * Fixed bug with url_for not working properly outside of a request when sub-domains are active. Thanks Pavel Skvazh. * Add non-minimization option to Routes and the Mapper for generation and recognition. * Add Routes 2.0 style syntax for making routes and regexp. For example, this route will now work: '{controller}/{action}/{id}'. * Fixed Routes to not use quote_plus when making URL's. * WARNING: Mapper now comes with hardcode_names set to True by default. This means routes generated by name must work for the URL. * Actually respect having urlcache disabled. * WARNING: Calling url_for with a set of args that returns None now throws an exception. Code that previously checked to see if a url could be made must be updated accordingly. * Updated url_for to return url in a literal for use in templating that may try to escape it again. * Added option to use X_FORWARDED_PROTO for proxying behind https to work easier. * Fixed map.resource to be less restrictive on id than just spaces. * Fixed Mapper.create_regs not being thread safe, particularly when always_scan=True. Release 1.8 (March 28, 2008) ============================ * Fixed bug of map.resource not allowing spaces in id. * Fixed url generation to properly handle unicode defaults in addition to unicode arguments. * Fixed url_for to handle lists as keyword args when generating query parameters. * WARNING: Changed map.resource to not use ';', for actions, but the normal '/'. This means that formatted URL's will also now have the format come AFTER the action. Ie: /messsages/4.xml;rss -> /messages/4/rss.xml Release 1.7.3 (May 28th, 2008) ============================== * Fixed triple escaping bug, since WSGI servers are responsible for basic unescaping. Release 1.7.2 (Feb. 27th, 2008) =============================== * Fixed bug with keyword args not being coerced to raw string properly. Release 1.7.1 (Nov. 16th, 2007) =============================== * Fixed bug with sub-domains from route defaults getting encoded to unicode resulting in a unicode route which then caused url_for to throw an exception. * Removed duplicate assignment in map.resource. Patch by Mike Naberezny. * Applied test patch fix for path checking. Thanks Mike Naberezny. * Added additional checking of remaining URL, to properly swallow periods in the appropriate context. Fixes #57. * Added mapper.hardcode_names option which restricts url generation to the named route during generation rather than using the routes default options during generation. * Fixed the special '_method' attribute not being recognized during POST requests of Content-Type 'multipart/form-data'. Release 1.7 (June 8th, 2007) ============================ * Fixed url_unquoting to only apply for strings. * Added _encoding option to individual routes to toggle decoding/encoding on a per route basis. * Fixed route matching so that '.' and other special chars are only part of the match should they not be followed by that character. Fixed regexp creation so that route parts with '.' in them aren't matched properly. Fixes #48. * Fixed Unicode decoding/encoding so that the URL decoding and encoding can be set on the mapper with mapper.encoding. Fixes #40. * Don't assume environ['CONTENT_TYPE'] always exists: it may be omitted according to the WSGI PEP. * Fixed Unicode decode/encoding of path_info dynamic/wildcard parts so that PATH_INFO will stay a raw string as it should. Fixes #51. * Fixed url_for (thus redirect_to) to throw an exception if a Unicode string is returned as that's an invalid URL. Fixes #46. * Fixed Routes middleware to only parse POST's if the content type is application/x-www-form-urlencoded for a HTML form. This properly avoids parsing wsgi.input when it doesn't need to be. Release 1.6.3 (April 10th, 2007) ================================ * Fixed matching so that an attempt to match an empty path raises a RouteException. Fixes #44. * Added ability to use characters in URL's such as '-' and '_' in map.resource. Patch by Wyatt Baldwin. Fixes #45. * Updated Mapper.resource handling with name_prefix and path_prefix checking to specify defaults. Also ensures that should either of them be set, they override the prefixes should parent_resource be specified. Patch by Wyatt Baldwin. Fixes #42. * Added utf-8 decoding of incoming path arguments, with fallback to ignoring them in the very rare cases a malformed request URL is sent. Patch from David Smith. * Fixed treatment of '#' character as something that can be left off and used in route paths. Found by Mike Orr. * Added ability to specify parent resource to map.resource command. Patch from Wyatt Baldwin. * Fixed formatted route issue with map.resource when additional collection methods are specified. Added unit tests to verify the collection methods work properly. * Updated URL parsing to properly use HTTP_HOST for hostname + port info before falling back to SERVER_PORT and SERVER_NAME. Fixes #43. * Added member_name and collection_name setting to Route object when made with map.resource. * Updated routes.middleware to make the Routes matched accessible as environ['routes.route']. * Updating mapper object to use thread local for request data (such as environ) and middleware now deletes environ references at the end of the request. * Added explicit option to Routes and Mapper. Routes _explicit setting will prevent the Route defaults from being implicitly set, while setting Mapper to explicit will prevent Route implicit defaults and stop url_for from using Route memory. Fixes #38. * Updated config object so that the route is attached if possible. * Adding standard logging usage with debug messages. * Added additional test for normal '.' match and fixed new special matching to match it properly. Thanks David Smith. * Fixed hanging special char issue with 'special' URL chars at the end of a URL that are missing the variable afterwards. * Changed Routes generation and recognition to handle other 'special' URL chars , . and ; as if they were /. This lets them be optionally left out of the resulting generated URL. Feature requested by David Smith. * Fixed lookahead assertion in regexp builder to properly handle two grouped patterns in a row. * Applied patch to generation and matching to handle Unicode characters properly. Reported with patch by David Smith. Release 1.6.2 (Jan. 5, 2007) ============================ * Fixed issue with method checking not properly handling different letter cases in REQUEST_METHOD. Reported by Sean Davis. * redirect_to now supports config.redirect returning a redirect, not just raising one. Release 1.6.1 (Dec. 29, 2006) ============================= * Fixed zipsafe flag to be False. Release 1.6 (Dec. 14th, 2006) ============================= * Fixed append_slash to take effect in the route generation itself instead of relying on url_for function. Reported by ToddG. * Added additional url_for tests to ensure map.resource generates proper named routes. * WARNING: Changed map.resource initialization to accept individual member and collection names to generate proper singular and plural route names. Those using map.resource will need to update their routes and url_for statements accordingly. * Added additional map.resource recognition tests. * Added WSGI middleware that does route resolving using new `WSGI.org Routing Vars Spec `_. * Added _absolute keyword option route connect to ignore SCRIPT_NAME settings. Suggested by Ian Bicking. Release 1.5.2 (Oct. 16th, 2006) =============================== * Fixed qualified keyword to keep host port names when used, unless a host is specifically passed in. Reported by Jon Rosebaugh. * Added qualified keyword option to url_for to have it generate a full URL. Resolves #29. * Fixed examples in url_for doc strings so they'll be accurate. Release 1.5.1 (Oct. 4th, 2006) ============================== * Fixed bug with escaping part names in the regular expression, reported by James Taylor. Release 1.5 (Sept. 19th, 2006) ============================== * Significant updates to map.resource and unit tests that comb it thoroughly to ensure its creating all the proper routes (it now is). Increased unit testing coverage to 95%. * Added unit tests to ensure controller_scan works properly with nested controller files and appropriately scans the directory structure. This brings the Routes util module up to full code coverage. * Fixed url_for so that when the protocol is changed, port information is removed from the host. * Added more thorough testing to _RequestConfig object and the ability to set your own object. This increases testing coverage of the __init__ module to 100%. * Fixed bug with sub_domain not maintaining port information in url_for and added unit tests. Reported by Jonathan Rosebaugh. * Added unit tests to ensure sub_domain option works with named routes, cleaned up url_for memory argument filtering. Fixed bug with named routes and sub_domain option not working together, reported by Jonathan Rosebaugh. * Changed order in which sub-domain is added to match-dict so it can be used in a conditions function. Release 1.4.1 (Sept. 6th, 2006) =============================== * Added sub_domains option to mapper, along with sub_domains_ignore list for subdomains that are considered equivilant to the main domain. When sub_domains is active, url_for will now take a sub_domain option that can alter the host the route will go to. * Added ability for filter functions to provide a _host, _protocol, _anchor arg which is then used to create the URL with the appropriate host/protocol/anchor destination. * Patch applied from Ticket #28. Resolves issue with Mapper's controller_scan function requiring a valid directory argument. Submitted by Zoran Isailovski. Release 1.4 (July 21, 2006) =========================== * Fixed bug with map.resource related to member methods, found in Rails version. * Fixed bug with map.resource member methods not requiring a member id. * Fixed bug related to handling keyword argument controller. * Added map.resource command which can automatically generate a batch of routes intended to be used in a REST-ful manner by a web framework. * Added URL generation handling for a 'method' argument. If 'method' is specified, it is not dropped and will be changed to '_method' for use by the framework. * Added conditions option to map.connect. Accepts a dict with optional keyword args 'method' or 'function'. Method is a list of HTTP methods that are valid for the route. Function is a function that will be called with environ, matchdict where matchdict is the dict created by the URL match. * Fixed redirect_to function for using absolute URL's. redirect_to now passes all args to url_for, then passes the resulting URL to the redirect function. Reported by climbus. Release 1.3.2 (April 30th, 2006) ================================ * Fixed _filter bug with inclusion in match dict during matching, reported by David Creemer. * Fixed improper url quoting by using urllib.encode, patch by Jason Culverhouse. Release 1.3.1 (April 4th, 2006) =============================== * Mapper has an optional attribute ``append_slash``. When set to ``True``, any URL's generated will have a slash appended to the end. * Fixed prefix option so that if the PATH_INFO is empty after prefix regexp, its set to '/' so the match proceeds ok. * Fixed prefix bug that caused routes after the initial one to not see the proper url for matching. Caught by Jochen Kupperschmidt. Release 1.3 (Feb. 25th, 2006) ============================= * url_for keyword filters: Named routes can now have a _filter argument that should specify a function that takes a dict as its sole argument. The dict will contain the full set of keywords passed to url_for, which the function can then modify as it pleases. The new dict will then be used as if it was the original set of keyword args given to url_for. * Fixed Python 2.3 incompatibility due to using keyword arg for a sort statement when using the built-in controller scanner. Release 1.2 (Feb. 17th, 2006) ============================= * If a named route doesn't exist, and a url_for call is used, instead of using the keyword arguments to generate a URL, they will be used as query args for the raw URL supplied. (Backwards Incompatible) * If Mapper has debug=True, using match will return two additional values, the route that matched, if one did match. And a list of routes that were tried, and information about why they didn't pass. * url_for enhancements: Can now be used with 'raw' URL's to generate proper url's for static content that will then automatically include SCRIPT_NAME if necessary Static named routes can now be used to shortcut common path information as desired. * Controller Scanner will now sort controller names so that the longest one is first. This ensures that the deepest nested controller is executed first before more shallow ones to increase predictability. * Controller Scanner now scans directories properly, the version in 1.1 left off the directory prefix when created the list of controllers. (Thanks to Justin for drawing my attention to it) Release 1.1 (Jan. 13th, 2006) ============================= * Routes Mapper additions: Now takes several optional arguments that determine how it will generate the regexp's. Can now hold a function for use when determining what the available controllers are. Comes with a default directory scanner Given a directory for the default scanner or a function, the Mapper will now automatically run it to get the controller list when needed * Syntax available for splitting routes to allow more complex route paths, such as ':controller/:(action)-:(id).html' * Easier setup/integration with Routes per request. Setting the environ in a WSGI environ will run match, and setup everything needed for url_for/etc. Release 1.0.2 (Dec. 30th, 2005) =============================== * Routes where a default was present but None were filling in improper values. * Passing a 0 would evaluate to None during generation, resulting in missing URL parts Release 1.0.1 (Dec. 18th, 2005) =============================== * Request Local Callable - You can now designate your own callable function that should then be used to store the request_config data. This is most useful for environments where its possible multiple requests might be running in a single thread. The callable should return a request specific object for attributes to be attached. See routes.__init__.py for more information. Release 1.0 (Nov. 21st, 2005) ============================= * routes.__init__ will now load the common symbols most people will want to actually use. Thus, you can either:: from routes import * Or:: from routes import request_config, Mapper The following names are available for importing from routes:: request_config, Mapper, url_for, redirect_to * Route Names - You can now name a route, which will save a copy of the defaults defined for later use by url_for or redirect_to. Thus, a route and url_for looking like this:: m.connect('home', controller='blog', action='splash') url_for(controller='blog', action='splash') # => /home Can now be used with a name:: m.connect('home_url','home', controller='blog', action='splash') url_for('home_url') # => /home Additional keywords can still be added to url_for and will override defaults in the named route. * Trailing / - Route recognition earlier failed on trailing slashes, not really a bug, not really a feature I guess. Anyways, trailing slashes are o.k. now as in the Rails version. * redirect_to now has two sets of tests to ensure it works properly Routes-2.3.1/MANIFEST.in0000644000175000017500000000016112456520011014060 0ustar benben00000000000000recursive-include docs * include CHANGELOG.rst include LICENSE.txt global-exclude .DS_Store *.hgignore *.hgtags Routes-2.3.1/routes/0000755000175000017500000000000012676765171013673 5ustar benben00000000000000Routes-2.3.1/routes/base.py0000644000175000017500000000020612456520011015127 0ustar benben00000000000000"""Route and Mapper core classes""" from routes import request_config from routes.mapper import Mapper from routes.route import Route Routes-2.3.1/routes/route.py0000644000175000017500000007072712553617302015402 0ustar benben00000000000000import re import sys from six.moves import urllib if sys.version < '2.4': from sets import ImmutableSet as frozenset import six from six.moves.urllib import parse as urlparse from routes.util import _url_quote as url_quote, _str_encode, as_unicode class Route(object): """The Route object holds a route recognition and generation routine.

By default, the member_name name will also be assumed to map to a controller you create. The concept of a web resource maps somewhat directly to 'CRUD' operations. The overlying things to keep in mind is that mapping a resource is about handling creating, viewing, and editing that resource. All keyword arguments are optional. ``controller`` If specified in the keyword args, the controller will be the actual controller used, but the rest of the naming conventions used for the route names and URL paths are unchanged. ``collection`` Additional action mappings used to manipulate/view the entire set of resources provided by the controller. Example:: map.resource('message', 'messages', collection={'rss':'GET'}) # GET /message/rss (maps to the rss action) # also adds named route "rss_message" ``member`` Additional action mappings used to access an individual 'member' of this controllers resources. Example:: map.resource('message', 'messages', member={'mark':'POST'}) # POST /message/1/mark (maps to the mark action) # also adds named route "mark_message" ``new`` Action mappings that involve dealing with a new member in the controller resources. Example:: map.resource('message', 'messages', new={'preview':'POST'}) # POST /message/new/preview (maps to the preview action) # also adds a url named "preview_new_message" ``path_prefix`` Prepends the URL path for the Route with the path_prefix given. This is most useful for cases where you want to mix resources or relations between resources. ``name_prefix`` Perpends the route names that are generated with the name_prefix given. Combined with the path_prefix option, it's easy to generate route names and paths that represent resources that are in relations. Example:: map.resource('message', 'messages', controller='categories', path_prefix='/category/:category_id', name_prefix="category_") # GET /category/7/message/1 # has named route "category_message" ``requirements`` A dictionary that restricts the matching of a variable. Can be used when matching variables with path_prefix. Example:: map.resource('message', 'messages', path_prefix='{project_id}/', requirements={"project_id": R"\d+"}) # POST /01234/message # success, project_id is set to "01234" # POST /foo/message # 404 not found, won't be matched by this route ``parent_resource`` A ``dict`` containing information about the parent resource, for creating a nested resource. It should contain the ``member_name`` and ``collection_name`` of the parent resource. This ``dict`` will be available via the associated ``Route`` object which can be accessed during a request via ``request.environ['routes.route']`` If ``parent_resource`` is supplied and ``path_prefix`` isn't, ``path_prefix`` will be generated from ``parent_resource`` as "/:_id".

Patch by Davanum Srinivas (PR #65). Release 2.3 (March 28, 2016) ============================ * Fix sub_domain equivalence check. Patch by Nikita Uvarov * Add support for protocol-relative URLs generation (i.e. starting with double slash ``//``). PR #60. Patch by Sviatoslav Sydorenko. * Add support for the ``middleware`` extra requirement, making possible to depend on ``webob`` optionally. PR #59. Patch by Sviatoslav Sydorenko. * Fix matching of an empty string route, which led to exception in earlier versions. PR #58. Patch by Sviatoslav Sydorenko. * Add support for the ``requirements`` option when using mapper.resource to create routes. PR #57. Patch by Sean Dague. * Concatenation fix when using submappers with path prefixes. Multiple submappers combined the path prefix inside the controller argument in non-obvious ways. The controller argument will now be properly carried through when using submappers. PR #28. Release 2.2 (July 21, 2015) =========================== * Fix Python 3 support. Patch by Victor Stinner. Release 2.1 (January 17, 2015) ============================== * Fix 3 other route matching groups in route.py to use anonymous groups for optional sections to avoid exceeding regex limits. Fixes #15. * Printing a mapper now includes the Controller/action parameters from the route. Fixes #11. * Fix regression that didn't allow passing in params 'host', 'protocol', or 'anchor'. They can now be passed in with a trailing '_' as was possible before commit d1d1742903fa5ca24ef848a6ae895303f2661b2a. Fixes #7. * URL generation with/without SCRIPT_NAME was resulting in the URL cache failing to return the appropriate cached URL generation. The URL cache should always include the SCRIPT_NAME, even if its empty, in the cache to avoid this, and now does. Fixes #6. * Extract Route creation into separate method in Mapper. Subclasses of Route can be created by Mappers now. * Use the first X_FORWARDED_FOR value if there are multiple proxies in the path. Fixes #5. Release 2.0 (November 17, 2013) =============================== * Python 3.2/3.3 Support. Fixes Issue #2. Thanks to Alejandro Sánchez for the pull request! Release 1.13 (March 12, 2012) ============================= * Fix bug with dots forcing extension by default. The portion with the dot can now be recognized. Patch by Michael Basnight. Release 1.12.3 (June 5, 2010) ============================= * Fix bug with URLGenerator not properly including SCRIPT_NAME when generating URL's and the singleton is not present. Release 1.12.2 (May 5, 2010) ============================ * Fix bug with routes URLGenerator not properly including SCRIPT_NAME when generating qualified URL's. Release 1.12.1 (March 11, 2010) =============================== * Fix bug with routes not generating URL's with callables in defaults. * Fix bug with routes not handling sub-domain defaults during generation. Release 1.12 (February 28, 2010) ================================ * Split up the Routes docs. * Fix bug with relative URL's using qualified merging host and URL without including the appropriate slash. Fixes #13. * Fix bug with mapper.extend and Routes modifying their original args. Fixes #24. * Fix url.current() not returning current args when explicit is True. * Added explicit way to directly use the Mapper to match with environ. * Fix bug with improper len placement for submapper. * Adding regular expression builder for entire regexp for faster rejection in a single regexp match should none of the routes match. * Give Mapper a tabular string representation. * Make SubMapper objects nestable and add route-generation helpers. * Add SubMapper-based collections. * Make the deprecated Mapper.minimization False (disabled) by default. * Make the mapper explicit (true) by default. Release 1.11 (September 28, 2009) ================================= * Extensive documentation rewrite. * Added Mapper.extend function that allows one to add lists of Routes objects to the mapper in one batch, optionally with a path_prefix. * Added Mapper.submapper function that returns a SubMapper object to enable easier declaration of routes that have multiple keyword argument options in common. * Mapper controller_scan argument now handles None, and lists of controller names in addition to a callable. * Route object now takes a name parameter, which is the name it responds to. This name is automatically added when called by using Mapper's connect class method. * Added optional LRU object for use with Routes when URL's change too often for the Routes urlcache dict to be a viable option. Release 1.10.3 (February 8, 2009) ================================= * Tweak to use WebOb Request rather than Paste. * Performance tweaks for URL recognition. * Bugfix for routes.middleware not re.escaping the path_info before moving it to the script name. Release 1.10.2 (January 11, 2009) ================================= * Bugfix for unicode encoding problems with non-minimized Route generation. Spotted by Wichert Akkerman. * Bugfix for when environ is {} in unit tests. Release 1.10.1 (September 27, 2008) =================================== * Removing LRU cache due to performance and threading issues. Cache does hit a max-size for the given routes. Release 1.10 (September 24, 2008) ================================= * Adding LRU cache instead of just dict for caching generated routes. This avoids slow memory leakage over long-running and non-existent route generation. * Adding URLGenerator object. * Adding redirect routes. * Static routes can now interpolate variable parts in the path if using {} variable part syntax. * Added sub_domain condition option to accept False or None, to require that there be no sub-domain provided for the route to match. Release 1.9.2 (July 8, 2008) ============================ * Fixed bug in url_for which caused it to return a literal when it shouldn't have. Release 1.9.1 (June 28, 2008) ============================= * Fixed bug in formatted route recognition with formatting being absorbed into the id. Release 1.9 (June 12, 2008) =========================== * Fix undefined arg bug in url_for. * Fixed bug with url_for not working properly outside of a request when sub-domains are active. Thanks Pavel Skvazh. * Add non-minimization option to Routes and the Mapper for generation and recognition. * Add Routes 2.0 style syntax for making routes and regexp. For example, this route will now work: '{controller}/{action}/{id}'. * Fixed Routes to not use quote_plus when making URL's. * WARNING: Mapper now comes with hardcode_names set to True by default. This means routes generated by name must work for the URL. * Actually respect having urlcache disabled. * WARNING: Calling url_for with a set of args that returns None now throws an exception. Code that previously checked to see if a url could be made must be updated accordingly. * Updated url_for to return url in a literal for use in templating that may try to escape it again. * Added option to use X_FORWARDED_PROTO for proxying behind https to work easier. * Fixed map.resource to be less restrictive on id than just spaces. * Fixed Mapper.create_regs not being thread safe, particularly when always_scan=True. Release 1.8 (March 28, 2008) ============================ * Fixed bug of map.resource not allowing spaces in id. * Fixed url generation to properly handle unicode defaults in addition to unicode arguments. * Fixed url_for to handle lists as keyword args when generating query parameters. * WARNING: Changed map.resource to not use ';', for actions, but the normal '/'. This means that formatted URL's will also now have the format come AFTER the action. Ie: /messsages/4.xml;rss -> /messages/4/rss.xml Release 1.7.3 (May 28th, 2008) ============================== * Fixed triple escaping bug, since WSGI servers are responsible for basic unescaping. Release 1.7.2 (Feb. 27th, 2008) =============================== * Fixed bug with keyword args not being coerced to raw string properly. Release 1.7.1 (Nov. 16th, 2007) =============================== * Fixed bug with sub-domains from route defaults getting encoded to unicode resulting in a unicode route which then caused url_for to throw an exception. * Removed duplicate assignment in map.resource. Patch by Mike Naberezny. * Applied test patch fix for path checking. Thanks Mike Naberezny. * Added additional checking of remaining URL, to properly swallow periods in the appropriate context. Fixes #57. * Added mapper.hardcode_names option which restricts url generation to the named route during generation rather than using the routes default options during generation. * Fixed the special '_method' attribute not being recognized during POST requests of Content-Type 'multipart/form-data'. Release 1.7 (June 8th, 2007) ============================ * Fixed url_unquoting to only apply for strings. * Added _encoding option to individual routes to toggle decoding/encoding on a per route basis. * Fixed route matching so that '.' and other special chars are only part of the match should they not be followed by that character. Fixed regexp creation so that route parts with '.' in them aren't matched properly. Fixes #48. * Fixed Unicode decoding/encoding so that the URL decoding and encoding can be set on the mapper with mapper.encoding. Fixes #40. * Don't assume environ['CONTENT_TYPE'] always exists: it may be omitted according to the WSGI PEP. * Fixed Unicode decode/encoding of path_info dynamic/wildcard parts so that PATH_INFO will stay a raw string as it should. Fixes #51. * Fixed url_for (thus redirect_to) to throw an exception if a Unicode string is returned as that's an invalid URL. Fixes #46. * Fixed Routes middleware to only parse POST's if the content type is application/x-www-form-urlencoded for a HTML form. This properly avoids parsing wsgi.input when it doesn't need to be. Release 1.6.3 (April 10th, 2007) ================================ * Fixed matching so that an attempt to match an empty path raises a RouteException. Fixes #44. * Added ability to use characters in URL's such as '-' and '_' in map.resource. Patch by Wyatt Baldwin. Fixes #45. * Updated Mapper.resource handling with name_prefix and path_prefix checking to specify defaults. Also ensures that should either of them be set, they override the prefixes should parent_resource be specified. Patch by Wyatt Baldwin. Fixes #42. * Added utf-8 decoding of incoming path arguments, with fallback to ignoring them in the very rare cases a malformed request URL is sent. Patch from David Smith. * Fixed treatment of '#' character as something that can be left off and used in route paths. Found by Mike Orr. * Added ability to specify parent resource to map.resource command. Patch from Wyatt Baldwin. * Fixed formatted route issue with map.resource when additional collection methods are specified. Added unit tests to verify the collection methods work properly. * Updated URL parsing to properly use HTTP_HOST for hostname + port info before falling back to SERVER_PORT and SERVER_NAME. Fixes #43. * Added member_name and collection_name setting to Route object when made with map.resource. * Updated routes.middleware to make the Routes matched accessible as environ['routes.route']. * Updating mapper object to use thread local for request data (such as environ) and middleware now deletes environ references at the end of the request. * Added explicit option to Routes and Mapper. Routes _explicit setting will prevent the Route defaults from being implicitly set, while setting Mapper to explicit will prevent Route implicit defaults and stop url_for from using Route memory. Fixes #38. * Updated config object so that the route is attached if possible. * Adding standard logging usage with debug messages. * Added additional test for normal '.' match and fixed new special matching to match it properly. Thanks David Smith. * Fixed hanging special char issue with 'special' URL chars at the end of a URL that are missing the variable afterwards. * Changed Routes generation and recognition to handle other 'special' URL chars , . and ; as if they were /. This lets them be optionally left out of the resulting generated URL. Feature requested by David Smith. * Fixed lookahead assertion in regexp builder to properly handle two grouped patterns in a row. * Applied patch to generation and matching to handle Unicode characters properly. Reported with patch by David Smith. Release 1.6.2 (Jan. 5, 2007) ============================ * Fixed issue with method checking not properly handling different letter cases in REQUEST_METHOD. Reported by Sean Davis. * redirect_to now supports config.redirect returning a redirect, not just raising one. Release 1.6.1 (Dec. 29, 2006) ============================= * Fixed zipsafe flag to be False. Release 1.6 (Dec. 14th, 2006) ============================= * Fixed append_slash to take effect in the route generation itself instead of relying on url_for function. Reported by ToddG. * Added additional url_for tests to ensure map.resource generates proper named routes. * WARNING: Changed map.resource initialization to accept individual member and collection names to generate proper singular and plural route names. Those using map.resource will need to update their routes and url_for statements accordingly. * Added additional map.resource recognition tests. * Added WSGI middleware that does route resolving using new `WSGI.org Routing Vars Spec `_. * Added _absolute keyword option route connect to ignore SCRIPT_NAME settings. Suggested by Ian Bicking. Release 1.5.2 (Oct. 16th, 2006) =============================== * Fixed qualified keyword to keep host port names when used, unless a host is specifically passed in. Reported by Jon Rosebaugh. * Added qualified keyword option to url_for to have it generate a full URL. Resolves #29. * Fixed examples in url_for doc strings so they'll be accurate. Release 1.5.1 (Oct. 4th, 2006) ============================== * Fixed bug with escaping part names in the regular expression, reported by James Taylor. Release 1.5 (Sept. 19th, 2006) ============================== * Significant updates to map.resource and unit tests that comb it thoroughly to ensure its creating all the proper routes (it now is). Increased unit testing coverage to 95%. * Added unit tests to ensure controller_scan works properly with nested controller files and appropriately scans the directory structure. This brings the Routes util module up to full code coverage. * Fixed url_for so that when the protocol is changed, port information is removed from the host. * Added more thorough testing to _RequestConfig object and the ability to set your own object. This increases testing coverage of the __init__ module to 100%. * Fixed bug with sub_domain not maintaining port information in url_for and added unit tests. Reported by Jonathan Rosebaugh. * Added unit tests to ensure sub_domain option works with named routes, cleaned up url_for memory argument filtering. Fixed bug with named routes and sub_domain option not working together, reported by Jonathan Rosebaugh. * Changed order in which sub-domain is added to match-dict so it can be used in a conditions function. Release 1.4.1 (Sept. 6th, 2006) =============================== * Added sub_domains option to mapper, along with sub_domains_ignore list for subdomains that are considered equivilant to the main domain. When sub_domains is active, url_for will now take a sub_domain option that can alter the host the route will go to. * Added ability for filter functions to provide a _host, _protocol, _anchor arg which is then used to create the URL with the appropriate host/protocol/anchor destination. * Patch applied from Ticket #28. Resolves issue with Mapper's controller_scan function requiring a valid directory argument. Submitted by Zoran Isailovski. Release 1.4 (July 21, 2006) =========================== * Fixed bug with map.resource related to member methods, found in Rails version. * Fixed bug with map.resource member methods not requiring a member id. * Fixed bug related to handling keyword argument controller. * Added map.resource command which can automatically generate a batch of routes intended to be used in a REST-ful manner by a web framework. * Added URL generation handling for a 'method' argument. If 'method' is specified, it is not dropped and will be changed to '_method' for use by the framework. * Added conditions option to map.connect. Accepts a dict with optional keyword args 'method' or 'function'. Method is a list of HTTP methods that are valid for the route. Function is a function that will be called with environ, matchdict where matchdict is the dict created by the URL match. * Fixed redirect_to function for using absolute URL's. redirect_to now passes all args to url_for, then passes the resulting URL to the redirect function. Reported by climbus. Release 1.3.2 (April 30th, 2006) ================================ * Fixed _filter bug with inclusion in match dict during matching, reported by David Creemer. * Fixed improper url quoting by using urllib.encode, patch by Jason Culverhouse. Release 1.3.1 (April 4th, 2006) =============================== * Mapper has an optional attribute ``append_slash``. When set to ``True``, any URL's generated will have a slash appended to the end. * Fixed prefix option so that if the PATH_INFO is empty after prefix regexp, its set to '/' so the match proceeds ok. * Fixed prefix bug that caused routes after the initial one to not see the proper url for matching. Caught by Jochen Kupperschmidt. Release 1.3 (Feb. 25th, 2006) ============================= * url_for keyword filters: Named routes can now have a _filter argument that should specify a function that takes a dict as its sole argument. The dict will contain the full set of keywords passed to url_for, which the function can then modify as it pleases. The new dict will then be used as if it was the original set of keyword args given to url_for. * Fixed Python 2.3 incompatibility due to using keyword arg for a sort statement when using the built-in controller scanner. Release 1.2 (Feb. 17th, 2006) ============================= * If a named route doesn't exist, and a url_for call is used, instead of using the keyword arguments to generate a URL, they will be used as query args for the raw URL supplied. (Backwards Incompatible) * If Mapper has debug=True, using match will return two additional values, the route that matched, if one did match. And a list of routes that were tried, and information about why they didn't pass. * url_for enhancements: Can now be used with 'raw' URL's to generate proper url's for static content that will then automatically include SCRIPT_NAME if necessary Static named routes can now be used to shortcut common path information as desired. * Controller Scanner will now sort controller names so that the longest one is first. This ensures that the deepest nested controller is executed first before more shallow ones to increase predictability. * Controller Scanner now scans directories properly, the version in 1.1 left off the directory prefix when created the list of controllers. (Thanks to Justin for drawing my attention to it) Release 1.1 (Jan. 13th, 2006) ============================= * Routes Mapper additions: Now takes several optional arguments that determine how it will generate the regexp's. Can now hold a function for use when determining what the available controllers are. Comes with a default directory scanner Given a directory for the default scanner or a function, the Mapper will now automatically run it to get the controller list when needed * Syntax available for splitting routes to allow more complex route paths, such as ':controller/:(action)-:(id).html' * Easier setup/integration with Routes per request. Setting the environ in a WSGI environ will run match, and setup everything needed for url_for/etc. Release 1.0.2 (Dec. 30th, 2005) =============================== * Routes where a default was present but None were filling in improper values. * Passing a 0 would evaluate to None during generation, resulting in missing URL parts Release 1.0.1 (Dec. 18th, 2005) =============================== * Request Local Callable - You can now designate your own callable function that should then be used to store the request_config data. This is most useful for environments where its possible multiple requests might be running in a single thread. The callable should return a request specific object for attributes to be attached. See routes.__init__.py for more information. Release 1.0 (Nov. 21st, 2005) ============================= * routes.__init__ will now load the common symbols most people will want to actually use. Thus, you can either:: from routes import * Or:: from routes import request_config, Mapper The following names are available for importing from routes:: request_config, Mapper, url_for, redirect_to * Route Names - You can now name a route, which will save a copy of the defaults defined for later use by url_for or redirect_to. Thus, a route and url_for looking like this:: m.connect('home', controller='blog', action='splash') url_for(controller='blog', action='splash') # => /home Can now be used with a name:: m.connect('home_url','home', controller='blog', action='splash') url_for('home_url') # => /home Additional keywords can still be added to url_for and will override defaults in the named route. * Trailing / - Route recognition earlier failed on trailing slashes, not really a bug, not really a feature I guess. Anyways, trailing slashes are o.k. now as in the Rails version. * redirect_to now has two sets of tests to ensure it works properly Keywords: routes webob dispatch Platform: UNKNOWN Classifier: Development Status :: 5 - Production/Stable Classifier: Intended Audience :: Developers Classifier: License :: OSI Approved :: MIT License Classifier: Topic :: Internet :: WWW/HTTP Classifier: Topic :: Software Development :: Libraries :: Python Modules Classifier: Programming Language :: Python :: Implementation :: PyPy Classifier: Programming Language :: Python :: Implementation :: CPython Classifier: Programming Language :: Python Classifier: Programming Language :: Python :: 2 Classifier: Programming Language :: Python :: 2.6 Classifier: Programming Language :: Python :: 2.7 Classifier: Programming Language :: Python :: 3 Classifier: Programming Language :: Python :: 3.2 Classifier: Programming Language :: Python :: 3.3 Classifier: Programming Language :: Python :: 3.4 Classifier: Programming Language :: Python :: 3.5 Routes-2.3.1/README.rst0000644000175000017500000000122112456520011014007 0ustar benben00000000000000Routes is a Python re-implementation of the Rails routes system for mapping URL's to Controllers/Actions and generating URL's. Routes makes it easy to create pretty and concise URL's that are RESTful with little effort. Speedy and dynamic URL generation means you get a URL with minimal cruft (no big dangling query args). Shortcut features like Named Routes cut down on repetitive typing.
