In Django, how do I get the name of the pattern that was followed for a particular URL within a template?

I have been doing lots of Googling on this topic and have gone through plenty of Django docs, but I can't seem to find a decent answer to what seems like ought to be a very simple question with a simple solution. So hopefully a Django vet out there can help.

Lets say I have the following urlconf:

urlpatterns = patterns('',
    ....
    url(r'^directory/users/$', UserView.as_view(), name='users'),
    url(r'^directory/users/(?P<user_id>[0-9]+)/$',UserView.as_view(), name='users'),
    ....
)

What I want to be able to do is test from within a template which pattern was followed, something like this:

{% if name_of_last_followed_url_pattern == 'users' %}
    ....
{% endif %}

Now one would think that Django would stash this away somewhere and be able to spit it back out to me. But I cannot find anything that corresponds to "name_of_last_followed_url_pattern" anywhere in the docs or in my searches. Any ideas how I might access this (or if not provided, why not)?

You need the context processors that adds the request to the template django.core.context_processors.request added to the TEMPLATE_CONTEXT_PROCESSORS. Then in the template you can do

{% if request.resolver_match.url_name == 'users' %}
....
{% endif %}

resolver_match has other attributes like namespaces, app_name. You can see here: https://docs.djangoproject.com/en/1.6/ref/urlresolvers/#django.core.urlresolvers.ResolverMatch
