>>> from django.core.urlresolvers import reverse >>> response = client.get(reverse('polls:index')) throws an error KeyError: 'polls' NoReverseMatch: 'polls' is not a registered namespace Here is my urls.py
from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^polls/', include('polls.urls', namespace = 'polls')), url(r'^admin/', admin.site.urls), ] /polls/urls.py
