Fixed #10061 -- Added namespacing for named URLs - most importantly, for the admin site, where the absence of this facility was causing problems. Thanks to the many people who contributed to and helped review this patch.
This change is backwards incompatible for anyone that is using the named URLs introduced in [9739]. Any usage of the old admin_XXX names need to be modified to use the new namespaced format; in many cases this will be as simple as a search & replace for "admin_" -> "admin:". See the docs for more details on the new URL names, and the namespace resolution strategy. git-svn-id: http://code.djangoproject.com/svn/django/trunk@11250 bcc190cf-cafb-0310-a4f2-bffc1f526a37

|

Defining URL Namespaces
|
||||
-----------------------
|
||||
|
||||
When you need to deploying multiple instances of a single application, it can
|
||||
be helpful to be able to differentiate between instances. This is especially
|
||||
important when using _`named URL patterns <naming-url-patterns>`, since
|
||||
multiple instances of a single application will share named URLs. Namespaces
|
||||
provide a way to tell these named URLs apart.
|
||||
|
||||
A URL namespace comes in two parts, both of which are strings:
|
||||
|
||||
* An **application namespace**. This describes the name of the application
|
||||
that is being deployed. Every instance of a single application will have
|
||||
the same application namespace. For example, Django's admin application
|
||||
has the somewhat predictable application namespace of ``admin``.
|
||||
|
||||
* An **instance namespace**. This identifies a specific instance of an
|
||||
application. Instance namespaces should be unique across your entire
|
||||
project. However, and instance namespace can be the same as the
|
||||
application namespace. This is used to specify a default instance of an
|
||||
application. For example, the default Django Admin instance has an
|
||||
instance namespace of ``admin``.
|
||||
|
||||
URL Namespaces can be specified in two ways.
|
||||
|
||||
Firstly, you can provide the applicaiton and instance namespace as arguments
|
||||
to the ``include()`` when you construct your URL patterns. For example,::
|
||||
|
||||
(r'^help/', include('apps.help.urls', namespace='foo', app_name='bar')),
|
||||
|
||||
This will include the URLs defined in ``apps.help.urls`` into the application
|
||||
namespace ``bar``, with the instance namespace ``foo``.
|
||||
|
||||
Secondly, you can include an object that contains embedded namespace data. If
|
||||
you ``include()`` a ``patterns`` object, that object will be added to the
|
||||
global namespace. However, you can also ``include()`` an object that contains
|
||||
a 3-tuple containing::
|
||||
|
||||
(<patterns object>, <application namespace>, <instance namespace>)
|
||||
|
||||
This will include the nominated URL patterns into the given application and
|
||||
instance namespace. For example, the ``urls`` attribute of Django's
|
||||
:class:`AdminSite` object returns a 3-tuple that contains all the patterns in
|
||||
an admin site, plus the name of the admin instance, and the application
|
||||
namespace ``admin``.
|
||||
|
||||
Once you have defined namespace URLs, you can reverse them. For details on
|
||||
reversing namespaced urls, see the documentation on :ref:`reversing namespaced
|
||||
URLs <topics-http-reversing-url-namespaces>`.

|
||||
URL namespaces
|
||||
--------------
|
||||
|
||||
.. versionadded:: 1.1
|
||||
|
||||
Namespaced URLs are specified using the `:` operator. For example, the main index
|
||||
page of the admin application is referenced using ``admin:index``. This indicates
|
||||
a namespace of ``admin``, and a named URL of ``index``.
|
||||
|
||||
Namespaces can also be nested. The named URL ``foo:bar:whiz`` would look for
|
||||
a pattern named ``whiz`` in the namespace ``bar`` that is itself defined within
|
||||
the top-level namespace ``foo``.
|
||||
|
||||
When given a namespaced URL (e.g.,, `myapp:index`) to resolve, Django splits
|
||||
the fully qualified name into parts, and then tries the following lookup:
|
||||
|
||||
1. Django then looks for a matching application namespace (in this
|
||||
example, ``myapp``). This will yield a list of instances of that
|
||||
application.
|
||||
|
||||
2. If there is a ``current`` application defined, Django finds and returns
|
||||
the URL resolver for that instance. The ``current`` can be specified
|
||||
as an attribute on the template context - applications that expect to
|
||||
have multiple deployments should set the ``current_app`` attribute on
|
||||
any ``Context`` or ``RequestContext`` that is used to render a
|
||||
template.
|
||||
|
||||
The current application can also be specified manually as an argument
|
||||
to the :method:``reverse()`` function.
|
||||
|
||||
3. If there is no current application. Django looks for a default
|
||||
application instance. The default application instance is the instance
|
||||
that has an instance namespace matching the application namespace (in
|
||||
this example, an instance of the ``myapp`` called ``myapp``)
|
||||
|
||||
4. If there is no default application instance, Django will pick the first
|
||||
deployed instance of the application, whatever it's instance name may be.
|
||||
|
||||
5. If the provided namespace doesn't match an application namespace in
|
||||
step 2, Django will attempt a direct lookup of the namespace as an
|
||||
instance namespace.
|
||||
|
||||
If there are nested namespaces, these steps are repeated for each part of the
|
||||
namespace until only the view name is unresolved. The view name will then be
|
||||
resolved into a URL in the namespace that has been found.
|
||||
|
||||
To show this resolution strategy in action, consider an example of two instances
|
||||
of ``myapp``: one called ``foo``, and one called ``bar``. ``myapp`` has a main
|
||||
index page with a URL named `index`. Using this setup, the following lookups are
|
||||
possible:
|
||||
|
||||
* If one of the instances is current - say, if we were rendering a utility page
|
||||
in the instance ``bar`` - ``myapp:index`` will resolve to the index page of
|
||||
the instance ``bar``.
|
||||
|
||||
* If there is no current instance - say, if we were rendering a page
|
||||
somewhere else on the site - ``myapp:index`` will resolve to the first
|
||||
registered instance of ``myapp``. Since there is no default instance,
|
||||
the first instance of ``myapp`` that is registered will be used. This could
|
||||
be ``foo`` or ``bar``, depending on the order they are introduced into the
|
||||
urlpatterns of the project.
|
||||
|
||||
* ``foo:index`` will always resolve to the index page of the instance ``foo``.
|
||||
|
||||
If there was also a default instance - i.e., an instance named `myapp` - the
|
||||
following would happen:
|
||||
|
||||
* If one of the instances is current - say, if we were rendering a utility page
|
||||
in the instance ``bar`` - ``myapp:index`` will resolve to the index page of
|
||||
the instance ``bar``.
|
||||
|
||||
* If there is no current instance - say, if we were rendering a page somewhere
|
||||
else on the site - ``myapp:index`` will resolve to the index page of the
|
||||
default instance.
|
||||
|
||||
* ``foo:index`` will again resolve to the index page of the instance ``foo``.
