25035	urlresolvers.reverse doesn't resolve a namespaced URL when passed a callable	Adam Brenecki	nobody	"When I pass a view callable to `django.core.urlresolvers.reverse`, it resolves correctly if the callable is in the top-level `urlpatterns`, or one in a `urlpatterns` that's been `include`d without a namespace, but not one that's been `include`d with a namespace.

I've noticed this behaviour in 1.7 and in the current HEAD of master (as of 736fb1838cc25f5faf57cd2a4f6b6ab32ff9aadc).

Here's a minimal example (all files not listed are as generated by `startproject`/`startapp`):

`testproj/urls.py`
{{{#!python
from django.conf.urls import url, include
from django.contrib import admin
import testapp.urls

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^testapp/', include(testapp.urls, namespace='testapp')),
]
}}}

`testapp/urls.py`
{{{#!python
from django.conf.urls import url, include
from django.contrib import admin
from . import views

urlpatterns = [
    url(r'^myview', views.test),
]
}}}

`testapp/views.py`
{{{#!python
from django.shortcuts import render

# Create your views here.
def test():
    pass
}}}

Which results in this:
{{{#!sh
> python manage.py shell

}}}

If I remove the namespace, everything works as expected."	Bug	closed	Core (URLs)	dev	Normal	duplicate			Unreviewed	0	0	0	0	0	0
