django.urls functions for use in URLconfs¶path()¶path(route, view, kwargs=None, name=None)¶Returns an element for inclusion in urlpatterns. For example:
from django.urls import include, path
urlpatterns = [
path('index/', views.index, name='main-view'),
path('bio/<username>/', views.bio, name='bio'),
path('articles/<slug:title>/', views.article, name='article-detail'),
path('articles/<slug:title>/<int:section>/', views.section, name='article-section'),
path('weblog/', include('blog.urls')),
...
]
The route argument should be a string or
gettext_lazy() (see
Translating URL patterns) that contains a URL pattern. The string
may contain angle brackets (like <username> above) to capture part of the
URL and send it as a keyword argument to the view. The angle brackets may
include a converter specification (like the int part of <int:section>)
which limits the characters matched and may also change the type of the
variable passed to the view. For example, <int:section> matches a string
of decimal digits and converts the value to an int. See
Django 如何处理一个请求 for more details.
The view argument is a view function or the result of
as_view() for class-based views. It can
also be an django.urls.include().
The kwargs argument 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
argument is useful.
re_path()¶re_path(route, view, kwargs=None, name=None)¶Returns an element for inclusion in urlpatterns. For example:
from django.urls import include, re_path
urlpatterns = [
re_path(r'^index/$', views.index, name='index'),
re_path(r'^bio/(?P<username>\w+)/$', views.bio, name='bio'),
re_path(r'^weblog/', include('blog.urls')),
...
]
The route argument should be a string or
gettext_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. When a match is made, captured
groups from the regular expression are passed to the view -- as named arguments
if the groups are named, and as positional arguments otherwise. The values are
passed as strings, without any type conversion.
The view, kwargs and name arguments are the same as for
path().
include()¶include(module, namespace=None)[源代码]¶include(pattern_list)include((pattern_list, app_namespace), namespace=None)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 or a 2-tuple containing such iterable plus the names of the
application namespaces.

See 包含其它的URLconfs and URL namespaces and included URLconfs.
In older versions, this function is located in django.conf.urls. The
old location still works for backwards compatibility.
register_converter()¶The function for registering a converter for use in path()
routes.
The converter argument is a converter class, and type_name is the
converter name to use in path patterns. See
Registering custom path converters for an example.
django.conf.urls functions for use in URLconfs¶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()¶This function is an alias to django.urls.re_path(). It's likely to be
deprecated in a future release.
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 accepts request and exception
arguments and returns an HttpResponseBadRequest.
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 accepts request and exception
arguments and returns an HttpResponseForbidden.
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 accepts request and exception
arguments and returns an HttpResponseNotFound.
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.
