django-registration - NoReverseMatch at /accounts/login/at /accounts/login/

问题

Trying to make django-registration work within the Django Tutorial polls projects.

I'm using Django 1.6, django-registration 1.0 and the django-registration-templates

When I try to access

http://localhost:8000/accounts/login/

I get

NoReverseMatch at /accounts/login/

Reverse for 'index' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

The line in the template, mysite/templates/base.html, that's cited in the error report is :

<a href="{% url 'index' %}">{% trans "Home" %}</a> |

And I do have a url with name 'index' in my polls.url :

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<pk>\d+)/$', views.DetailView.as_view(), name='detail'),
    url(r'^(?P<pk>\d+)/results/$', views.ResultsView.as_view(), name='results'),
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)

So I feel like that should work ? Help ?

polls.urls:

from django.conf.urls import patterns, url

from polls import views

urlpatterns = patterns('',
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<pk>\d+)/$', views.DetailView.as_view(), name='detail'),
    url(r'^(?P<pk>\d+)/results/$', views.ResultsView.as_view(), name='results'),
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)

mysite.urls:

from django.conf.urls import patterns, include, url
from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^accounts/', include('registration.backends.default.urls')),
)

registration.urls:

"""

installs; this allows the standard ``include('registration.urls')`` to

django-registration 1.0. For new installs, use

回答1:

OK I've figured out the problem here. The url with name 'index' was defined in polls.urls and so within the template I needed to change :

<a href="{% url 'index' %}">{% trans "Home" %}</a>

<a href="{% url 'polls:index' %}">{% trans "Home" %}</a>

As mentioned in the Django 1.6 documention of the url tag and which I quote here for convenience :

If you’d like to retrieve a namespaced URL, specify the fully qualified name:

{% url 'myapp:view-name' %}

This will follow the normal namespaced URL resolution strategy, including using any hints provided by the context as to the current application.
