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:

1	`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
