======================================
``django.conf.urls`` utility functions
======================================
.. module:: django.conf.urls
``static()``
============
.. function:: static.static(prefix, view=django.views.static.serve, **kwargs)
Helper function to return a URL pattern for serving files in debug mode::
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
``url()``
=========
.. function:: url(regex, view, kwargs=None, name=None)
``urlpatterns`` should be a list of ``url()`` instances. For example::
from django.conf.urls import include, url
urlpatterns = [
url(r'^index/$', index_view, name='main-view'),
url(r'^weblog/', include('blog.urls')),
...
]
2016-12-23 00:16:26 +00:00
The ``regex`` parameter should be a string or
:func:`~django.utils.translation.gettext_lazy()` (see
2016-12-23 00:16:26 +00:00
:ref:`translating-urlpatterns`) that contains a regular expression compatible
with Python's :py:mod:`re` module. Strings typically use raw string syntax
(``r''``) so that they can contain sequences like ``\d`` without the need to
escape the backslash with another backslash.
The ``view`` parameter is a view function or the result of
:meth:`~django.views.generic.base.View.as_view` for class-based views. It can
also be an :func:`include`.
The ``kwargs`` parameter allows you to pass additional arguments to the view
function or method. See :ref:`views-extra-options` for an example.
See :ref:`Naming URL patterns <naming-url-patterns>` for why the ``name``
parameter is useful.
``include()``
=============
.. function:: include(module, namespace=None)
2012-10-06 19:19:51 +00:00
include(pattern_list)
include((pattern_list, app_namespace), namespace=None)
2012-10-06 19:19:51 +00:00
A function that takes a full Python import path to another URLconf module
that should be "included" in this place. Optionally, the :term:`application
namespace` and :term:`instance namespace` where the entries will be included
into can also be specified.
Usually, the application namespace should be specified by the included
module. If an application namespace is set, the ``namespace`` argument
can be used to set a different instance namespace.
2012-10-06 19:19:51 +00:00
``include()`` also accepts as an argument either an iterable that returns
URL patterns or a 2-tuple containing such iterable plus the names of the
application namespaces.
2012-10-06 19:19:51 +00:00
:arg module: URLconf module (or module name)
:arg namespace: Instance namespace for the URL entries being included
:type namespace: string
:arg pattern_list: Iterable of :func:`django.conf.urls.url` instances
2012-10-06 19:19:51 +00:00
:arg app_namespace: Application namespace for the URL entries being included
:type app_namespace: string
:arg instance_namespace: Instance namespace for the URL entries being included
:type instance_namespace: string
See :ref:`including-other-urlconfs` and :ref:`namespaces-and-include`.
``handler400``
==============
.. data:: handler400
A callable, or a string representing the full Python import path to the view
that should be called if the HTTP client has sent a request that caused an error
condition and a response with a status code of 400.
By default, this is :func:`django.views.defaults.bad_request`. If you
implement a custom view, be sure it returns an
:class:`~django.http.HttpResponseBadRequest`.
``handler403``
==============
.. data:: handler403
A callable, or a string representing the full Python import path to the view
that should be called if the user doesn't have the permissions required to
access a resource.
By default, this is :func:`django.views.defaults.permission_denied`. If you
implement a custom view, be sure it returns an
:class:`~django.http.HttpResponseForbidden`.
``handler404``
==============
.. data:: handler404
A callable, or a string representing the full Python import path to the view
that should be called if none of the URL patterns match.
By default, this is :func:`django.views.defaults.page_not_found`. If you
implement a custom view, be sure it returns an
:class:`~django.http.HttpResponseNotFound`.
``handler500``
==============
.. data:: handler500
A callable, or a string representing the full Python import path to the view
that should be called in case of server errors. Server errors happen when you
have runtime errors in view code.
By default, this is :func:`django.views.defaults.server_error`. If you
implement a custom view, be sure it returns an
:class:`~django.http.HttpResponseServerError`.
