Make reverse_dict.getlist work with fully qualified module names

[Etienne Robillard]

The function _reverse_with_prefix in django/urls/resolvers.py doesn't handle fully qualified module names. This patch ensure that reverse() works in this case.

Can you please summarize the discussion and explain what use case this solves? Tests are also needed.

[Etienne Robillard]

I want to make Django 1.10 fully compatible with my urlpatterns configuration. I use a custom urlresolver module (notmm.utils.urlmap) to allow mapping url patterns to named views:

from notmm.utils.urlmap import RegexURLMap
urlpatterns = RegexURLMap()
urlpatterns.add_routes('foobar.views',  
 (r'^index.html$', 'index'),
)

add_routes() automatically create a fully qualified callback object to ensure the view function is a callable. However, Django doesn't handle fully qualified module names in reverse() without this patch.

I guess you might be running into problems because Django 1.10 removed support for string view arguments in url() (a25d3ce007b90a0516aed54fc1c5a16510a290e4 and/or 785cc71d5b3300e2702b0b2fc7316e58ca70b563). I'm not sure whether or not we can accommodate the use case, but as-is your patch crashes the test suite.

Please reopen if you can add more details and provide a tested patch.
