django-multiurl

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.
