# `django.conf.urls` utility functions

## `static()`

`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()`

`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')),
        ...
    ]

The `regex` parameter should be a string or `ugettext_lazy()` (see Translating URL patterns) that contains a regular expression compatible with Python’s `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 `as_view()` for class-based views. It can also be an `include()`.

The `kwargs` parameter allows you to pass additional arguments to the view function or method. See Passing extra options to view functions for an example.

See Naming URL patterns for why the `name` parameter is useful.

## `include()`

`include`(module, namespace=None, app_name=None)
`include`(pattern_list)
`include`((pattern_list, app_namespace), namespace=None)
`include`((pattern_list, app_namespace, instance_namespace))

  A function that takes a full Python import path to another URLconf module that should be “included” in this place. Optionally, the application namespace and 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.

  `include()` also accepts as an argument either an iterable that returns URL patterns, a 2-tuple containing such iterable plus the names of the application namespaces, or a 3-tuple containing the iterable and the names of both the application and instance namespace.

  Parámetros: | module – URLconf module (or module name) namespace (string) – Instance namespace for the URL entries being included app_name (string) – Application namespace for the URL entries being included pattern_list – Iterable of `django.conf.urls.url()` instances app_namespace (string) – Application namespace for the URL entries being included instance_namespace (string) – Instance namespace for the URL entries being included

See Including other URLconfs and URL namespaces and included URLconfs.

Obsoleto desde la versión 1.9: Support for the `app_name` argument is deprecated and will be removed in Django 2.0. Specify the `app_name` as explained in URL namespaces and included URLconfs instead.

Support for passing a 3-tuple is also deprecated and will be removed in Django 2.0. Pass a 2-tuple containing the pattern list and application namespace, and use the `namespace` argument instead.

Lastly, support for an instance namespace without an application namespace has been deprecated and will be removed in Django 2.0. Specify the application namespace or remove the instance namespace.

## `handler400`

`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 `'django.views.defaults.bad_request'`. If you implement a custom view, be sure it returns an `HttpResponseBadRequest`.

See the documentation about the 400 (bad request) view for more information.

## `handler403`

`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 `'django.views.defaults.permission_denied'`. If you implement a custom view, be sure it returns an `HttpResponseForbidden`.

See the documentation about the 403 (HTTP Forbidden) view for more information.

## `handler404`

`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 `'django.views.defaults.page_not_found'`. If you implement a custom view, be sure it returns an `HttpResponseNotFound`.

See the documentation about the 404 (HTTP Not Found) view for more information.

## `handler500`

`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 `'django.views.defaults.server_error'`. If you implement a custom view, be sure it returns an `HttpResponseServerError`.

See the documentation about the 500 (HTTP Internal Server Error) view for more information.
