Admin URL patterns are not aware of the app_namespace

[Markus Holtermann]

Given these files:

# testapp/views.py 
from django.core.urlresolvers import reverse
from django.http import HttpResponse

def testview(request):
    rev = reverse('admin:testview', current_app='something')
    return HttpResponse('Some Text %s' % rev)

# testapp/urls.py 
from django.conf.urls import patterns, url

urlpatterns = patterns('',
   url(r'^', 'testapp.views.testview', name='testview')
)

# testproject/urls.py 
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^foo/', include('testapp.urls', namespace='admin', app_name='something')),
)

I'd expect that the view testapp.views.testview is still available when resolving the 'admin:testview' with the current_app set explicitly. Instead I'm greeted with a NoReverseMatch at /foo/ error:

Traceback:

Changing the order of the of the patterns in the ROOTURL_CONF makes the admin inaccessible:

I talked to apollo13 about this and therefore mark it as accepted.

Um, MarkusH and I were talking about something slightly different, resetting to unreviewed.

Duplicate of #17914?

Ok, I misread the docs. In the ROOTURL_CONF it must be

url(r'^foo/', include('testapp.urls', namespace='something', app_name='admin')),

to make it work.
