I am struggling to get 'reverse' working when running tests for actions
defined in my admin.py files.
If I open a Django shell and run:
from django.core.urlresolvers import reverse
print reverse('admin:trees_alivetrees_changelist')
I get:
/admin/trees/alivetrees/
as expected.
But if I define a test file (called `test_admin_fail.py`):
from django.test import TestCase
from django.core.urlresolvers import reverse
class TreeAdminTest(TestCase):
def test_action_tree_mark_dead(self):
change_url = reverse('admin:trees_alivetrees_changelist')
self.assertContains(change_url, "alivetrees") # temporary test
and run it from the command line:
python manage.py test --traverse-namespace tests.trees.test_admin_fail -v 2
--settings=test_settings
then I get this error:
Traceback (most recent call last):
File "/dev/tests/trees/test_admin_fail.py", line 7, in

**kwargs))

<traceback object at 0x7fe779406c20>)
The test_settings.py file is used to create an in-memory database (and has
never itself caused any issues before).
Any guidance here would be appreciated; I have tried Googling for the
error, but the combination of admin, testing and reverse is one I have not
seen.
Thanks
