urls.ResolverMatch

class ResolverMatch [source]

func

The view function that would be used to serve the URL

args

The arguments that would be passed to the view function, as parsed from the URL.

kwargs

The keyword arguments that would be passed to the view function, as parsed from the URL.

url_name

The name of the URL pattern that matches the URL.

app_name

The application namespace for the URL pattern that matches the URL.

app_names

New in Django 1.9.

The list of individual namespace components in the full application namespace for the URL pattern that matches the URL. For example, if the app_name is 'foo:bar', then app_names will be ['foo', 'bar'].

namespace

The instance namespace for the URL pattern that matches the URL.

namespaces

The list of individual namespace components in the full instance namespace for the URL pattern that matches the URL. i.e., if the namespace is foo:bar, then namespaces will be ['foo', 'bar'].

view_name

The name of the view that matches the URL, including the namespace if there is one.

A ResolverMatch object can then be interrogated to provide information about the URL pattern that matches a URL:

# Resolve a URL
match = resolve('/some/path/')
# Print the URL pattern that matches the URL
print(match.url_name)

A ResolverMatch object can also be assigned to a triple:

func, args, kwargs = resolve('/some/path/')

One possible use of resolve() would be to test whether a view would raise a Http404 error before redirecting to it:

from django.urls import resolve
from django.http import HttpResponseRedirect, Http404
from django.utils.six.moves.urllib.parse import urlparse

def myview(request):
    next = request.META.get('HTTP_REFERER', None) or '/'
    response = HttpResponseRedirect(next)

    # modify the request and response as required, e.g. change locale
    # and set corresponding locale cookie

    view, args, kwargs = resolve(urlparse(next)[2])
    kwargs['request'] = request
    try:
        view(*args, **kwargs)
    except Http404:
        return HttpResponseRedirect('/')
    return response
