django-multiurl 1.5.0

Allow multiple views to match the same URL.

Have you ever wanted multiple views to match to the same URL? Now you can.

You may once have tried something like this:

urlpatterns = [
    url('/app/(\w+)/$', app.views.people),
    url('/app/(\w+)/$', app.views.place),
]

However, if you try this, /app/san-francisco/ will only map to app.views.people. Raising an Http404 from app.views.people doesn’t help: you only get a 404 in the browser because Django stops resolving URLs at the first match.

Well, django-multiurl solves this problem. Just pip install django-multiurl, then do this:

from multiurl import multiurl

urlpatterns = [
    multiurl(
        url('/app/(\w+)/$', app.views.people),
        url('/app/(\w+)/$', app.views.place),
    )
]

Now in your views, raise multiurl.ContinueResolving anywhere you’d like to break out of the view and keep resolving. For example, here’s what app.views.people might look like:

from multiurl import ContinueResolving

def people(request, name):
    try:
        person = Person.objects.get(name=name)
    except Person.DoesNotExist:
        raise ContinueResolving
    return render(...)

That’s it! ContinueResolving will cause multiurl to continue onto the next view (app.views.place, in this example).

A few notes to round things out:

• If you don’t want to use ContinueResolving – perhaps you’d rather continue using get_object_or_404, or you’re using third-party views that you can’t modify to raise ContinueResolving, you can pass a catch argument into multiurl to control which exceptions are considered “continue” statements. For example, to allow Http404 exceptions to continue resolving, do this:

  urlpatterns = [
      multiurl(
          url('/app/(\w+)/$', app.views.people),
          url('/app/(\w+)/$', app.views.place),
          catch = (Http404, ContinueResolving)
      )
  ]

  As you can see, catch should be a tuple of exceptions. It’s probably a good idea to always include ContinueResolving in the tuple.

• If the last view in a multiurl raises ContinueResolving (or another “continuing” exception), a 404 will be raised instead. That is, if resolving “falls off the end” of some multi-urls, you’ll get the 404 you expect.

• Reverse URL resolution just works as expected. Name your sub-URLs and then reverse your heart out.
