Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: url(r'^$', views.home, name='home')
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: url(r'^$', Home.as_view(), name='home')
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.conf.urls import url, include
2. Add a URL to urlpatterns: url(r'^blog/', include('blog.urls'))
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

The code above maps URLs, as simple :ref:`regular expressions <regex-howto>`,

use parenthesis to "capture" values from the URLs. When a user requests a page,
Django runs through each pattern, in order, and stops at the first one that
matches the requested URL. (If none of them matches, Django calls a
special-case 404 view.) This is blazingly fast, because the regular expressions

---------------------------------------------
The term "regex" is a commonly used short form meaning "regular expression",
which is a syntax for matching patterns in strings, or in this case, url
patterns. Django starts at the first regular expression and makes its way down
the list, comparing the requested URL against each regular expression until it
finds one that matches.
``route`` is a string that contains a URL pattern. When processing a request,
Django starts at the first pattern in ``urlpatterns`` and makes its way down
the list, comparing the requested URL against each pattern until it finds one
that matches.
Note that these regular expressions do not search GET and POST parameters, or
the domain name. For example, in a request to
``https://www.example.com/myapp/``, the URLconf will look for ``myapp/``. In a
request to ``https://www.example.com/myapp/?page=3``, the URLconf will also
look for ``myapp/``.
Patterns don't search GET and POST parameters, or the domain name. For example,
in a request to ``https://www.example.com/myapp/``, the URLconf will look for
``myapp/``. In a request to ``https://www.example.com/myapp/?page=3``, the
URLconf will also look for ``myapp/``.
If you need help with regular expressions, see `Wikipedia's entry`_ and the
documentation of the :mod:`re` module. Also, the O'Reilly book "Mastering
Regular Expressions" by Jeffrey Friedl is fantastic. In practice, however,
you don't need to be an expert on regular expressions, as you really only need
to know how to capture simple patterns. In fact, complex regexes can have poor
lookup performance, so you probably shouldn't rely on the full power of regexes.
Finally, a performance note: these regular expressions are compiled the first
time the URLconf module is loaded. They're super fast (as long as the lookups
aren't too complex as noted above).

:func:`~django.conf.urls.url` argument: view
:func:`~django.urls.path` argument: ``view``
--------------------------------------------
When Django finds a regular expression match, Django calls the specified view
function, with an :class:`~django.http.HttpRequest` object as the first
argument and any “captured” values from the regular expression as other
arguments. If the regex uses simple captures, values are passed as positional
arguments; if it uses named captures, values are passed as keyword arguments.
We'll give an example of this in a bit.

When somebody requests a page from your website -- say, "/polls/34/", Django
will load the ``mysite.urls`` Python module because it's pointed to by the
:setting:`ROOT_URLCONF` setting. It finds the variable named ``urlpatterns``
and traverses the regular expressions in order. After finding the match at
``'^polls/'``, it strips off the matching text (``"polls/"``) and sends the
remaining text -- ``"34/"`` -- to the 'polls.urls' URLconf for further
processing. There it matches ``r'^(?P<question_id>[0-9]+)/$'``, resulting in a

and traverses the patterns in order. After finding the match at ``'polls/'``,
it strips off the matching text (``"polls/"``) and sends the remaining text --
``"34/"`` -- to the 'polls.urls' URLconf for further processing. There it
matches ``'<int:question_id>/'``, resulting in a call to the ``detail()`` view
like so::
detail(request=<HttpRequest object>, question_id='34')
detail(request=<HttpRequest object>, question_id=34)
The ``question_id='34'`` part comes from ``(?P<question_id>[0-9]+)``. Using parentheses
around a pattern "captures" the text matched by that pattern and sends it as an
argument to the view function; ``?P<question_id>`` defines the name that will
be used to identify the matched pattern; and ``[0-9]+`` is a regular expression to
match a sequence of digits (i.e., a number).
The ``question_id=34`` part comes from ``<int:question_id>``. Using angle
brackets "captures" part of the URL and sends it as a keyword argument to the
view function. The ``:question_id>`` part of the string defines the name that
will be used to identify the matched pattern, and the ``<int:`` part is a
converter that determines what patterns should match this part of the URL path.
Because the URL patterns are regular expressions, there really is no limit on
what you can do with them. And there's no need to add URL cruft such as
``.html`` -- unless you want to, in which case you can do something like

==========
.. function:: path(route, view, kwargs=None, name=None)
.. versionadded:: 2.0
Returns an element for inclusion in ``urlpatterns``. For example::
from django.urls import include, path

path('bio/<username>/', views.bio, name='bio'),
path('articles/<slug:title>/', views.article, name='article-detail'),

path('weblog/', include('blog.urls')),
...
]
The ``route`` argument should be a string or
:func:`~django.utils.translation.gettext_lazy()` (see
:ref:`translating-urlpatterns`) 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
:ref:`how-django-processes-a-request` for more details.
The ``view`` argument 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:`django.urls.include`.
The ``kwargs`` argument allows you to pass additional arguments to the view

argument is useful.

(``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.

What's new in Django 2.0
========================
Simplified URL routing syntax
-----------------------------
The new :func:`django.urls.path()` function allows a simpler, more readable URL
routing syntax. For example, this example from previous Django releases::
url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),
could be written as::
path('articles/<int:year>/', views.year_archive),
The new syntax supports type coercion of URL parameters. In the example, the
view will receive the ``year`` keyword argument as an integer rather than as
a string.
The ``django.conf.urls.url()`` function from previous versions is now available
as :func:`django.urls.re_path`, however, the old location remains for backwards
compatibility, without an imminent deprecation. The old
``django.conf.urls.include()`` function is now importable from ``django.urls``
so you can use ``from django.urls import include, path, re_path`` in your
URLconfs.
The :doc:`/topics/http/urls` document is rewritten to feature the new syntax
and provide more details.

Path converters
===============
Named groups
============
The following path converters are available by default:
The above example used simple, *non-named* regular-expression groups (via
parenthesis) to capture bits of the URL and pass them as *positional* arguments
to a view. In more advanced usage, it's possible to use *named*
regular-expression groups to capture URL bits and pass them as *keyword*
arguments to a view.
* ``str`` - Matches any non-empty string, excluding the path separator, ``'/'``.
This is the default if a converter isn't included in the expression.
In Python regular expressions, the syntax for named regular-expression groups
* ``int`` - Matches zero or any positive integer. Returns an `int`.
* ``slug`` - Matches any slug string consisting of ASCII letters or numbers,
plus the hyphen and underscore characters. For example,
``building-your-1st-django-site``.
* ``uuid`` - Matches a formatted UUID. For example,
``075194d3-6885-417e-a8a8-6c931e272f00``. Returns a :class:`~uuid.UUID`
instance.
* ``path`` - Matches any non-empty string, including the path separator,
``'/'``. This allows you to match against a complete URL path rather than
just a segment of a URL path as with ``str``.
.. _registering-custom-path-converters:
Registering custom path converters
==================================
For more complex matching requirements, you can define your own path converters.
A converter is a class that includes the following:
* A ``regex`` class attribute, as a string.
* A ``to_python(self, value)`` method, which handles converting the matched
string into the type that should be passed to the view function. It should
raise ``ValueError`` if it can't convert the given value.
* A ``to_url(self, value)`` method, which handles converting the Python type
into a string to be used in the URL.
For example::
class FourDigitYearConverter:
regex = '[0-9]{4}'
def to_python(self, value):
return int(value)
def to_url(self, value):
return '%04d' % value
Register custom converter classes in your URLconf using
:func:`~django.urls.register_converter`::
from django.urls import register_converter, path
from . import converters, views
register_converter(converters.FourDigitYearConverter, 'yyyy')
urlpatterns = [
path('articles/2003/', views.special_case_2003),
path('articles/<yyyy:year>/', views.year_archive),
...
]
Using regular expressions
=========================
If the paths and converters syntax isn't sufficient for defining your URL
patterns, you can also use regular expressions. To do so, use
:func:`~django.urls.re_path` instead of :func:`~django.urls.path`.
In Python regular expressions, the syntax for named regular expression groups
is ``(?P<name>pattern)``, where ``name`` is the name of the group and
``pattern`` is some pattern to match.
Here's the above example URLconf, rewritten to use named groups::
Here's the example URLconf from earlier, rewritten using regular expressions::
from django.conf.urls import url
from django.urls import path, re_path
from . import views
urlpatterns = [
url(r'^articles/2003/$', views.special_case_2003),
url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),
url(r'^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/$', views.month_archive),
url(r'^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<day>[0-9]{2})/$', views.article_detail),
path('articles/2003/', views.special_case_2003),
re_path('articles/(?P<year>[0-9]{4})/', views.year_archive),
re_path('articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/', views.month_archive),
re_path('articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<slug>[^/]+)/', views.article_detail),
]
This accomplishes exactly the same thing as the previous example, with one
subtle difference: The captured values are passed to view functions as keyword
arguments rather than positional arguments. For example:
This accomplishes roughly the same thing as the previous example, except:
* A request to ``/articles/2005/03/`` would call the function
``views.month_archive(request, year='2005', month='03')``, instead
of ``views.month_archive(request, '2005', '03')``.
* The exact URLs that will match are slightly more constrained. For example,
the year 10000 will no longer match since the year integers are constrained
to be exactly four digits long.
* A request to ``/articles/2003/03/03/`` would call the function
``views.article_detail(request, year='2003', month='03', day='03')``.
* Each captured argument is sent to the view as a string, regardless of what
sort of match the regular expression makes.
In practice, this means your URLconfs are slightly more explicit and less prone
to argument-order bugs -- and you can reorder the arguments in your views'
function definitions. Of course, these benefits come at the cost of brevity;
some developers find the named-group syntax ugly and too verbose.
When switching from using :func:`~django.urls.path` to
:func:`~django.urls.re_path` or vice versa, it's particularly important to be
aware that the type of the view arguments may change, and so you may need to
adapt your views.
The matching/grouping algorithm
-------------------------------
Using unnamed regular expression groups
---------------------------------------
Here's the algorithm the URLconf parser follows, with respect to named groups
vs. non-named groups in a regular expression:
As well as the named group syntax, e.g. ``(?P<year>[0-9]{4})``, you can
also use the shorter unnamed group, e.g. ``([0-9]{4})``.
1. If there are any named arguments, it will use those, ignoring non-named
arguments.
This usage isn't particularly recommended as it makes it easier to accidentally
introduce errors between the intended meaning of a match and the arguments
of the view.
2. Otherwise, it will pass all non-named arguments as positional arguments.
In either case, using only one style within an given regex is recommended. When
both styles are mixed, any unnamed groups are ignored and only named groups are
passed to the view function.
In both cases, any extra keyword arguments that have been given as per `Passing
extra options to view functions`_ (below) will also be passed to the view.
Nested arguments
----------------
Regular expressions allow nested arguments, and Django will resolve them and
pass them to the view. When reversing, Django will try to fill in all outer
captured arguments, ignoring any nested captured arguments. Consider the
following URL patterns which optionally take a page argument::
from django.urls import re_path
urlpatterns = [
re_path(r'blog/(page-(\d+)/)?$', blog_articles), # bad
re_path(r'comments/(?:page-(?P<page_number>\d+)/)?$', comments), # good
]
Both patterns use nested arguments and will resolve: for example,
``blog/page-2/`` will result in a match to ``blog_articles`` with two
positional arguments: ``page-2/`` and ``2``. The second pattern for
``comments`` will match ``comments/page-2/`` with keyword argument
``page_number`` set to 2. The outer argument in this case is a non-capturing
argument ``(?:...)``.
The ``blog_articles`` view needs the outermost captured argument to be reversed,
``page-2/`` or no arguments in this case, while ``comments`` can be reversed
with either no arguments or a value for ``page_number``.
Nested captured arguments create a strong coupling between the view arguments
and the URL as illustrated by ``blog_articles``: the view receives part of the
URL (``page-2/``) instead of only the value the view is interested in. This
coupling is even more pronounced when reversing, since to reverse the view we
need to pass the piece of URL instead of the page number.
As a rule of thumb, only capture the values the view needs to work with and
use non-capturing arguments when the regular expression needs an argument but
the view ignores it.
What the URLconf searches against
