Answer 1

Da Sie password_change innerhalb Anwendung hinzufügen url.py

url(r'^password-change/$', password_change, {'post_change_redirect': 'account:password_change_done'}, name='password_change'), 
url(r'^password-change/done/$', password_change_done, name='password_change_done'), 

wo account ist ein Namensraum von Anwendungs-URLs: Sie sollten post_change url einschließlich Anwendungsname mit post_change_redirect Argument angeben.

Answer 2

Das Problem ist wahrscheinlich zu öffnen versuche, dass Ihre URLs sind Namespace und Sie haben vergessen, den Namespace zu verwenden. Versuchen:

{% url 'account:password_change_done' %} 

oder

reverse('account:password_change_done') 

Denken Sie daran, Ihre Namen Namespace, sonst django möglicherweise nicht in der Lage sein, sie zu finden. Sie können den Namespace finden, die Sie verwenden, indem man (wenn es nicht account ist), wo Sie die URLs für die Anmeldung sind inklusive usw. Es sollte in etwa so aussehen:

url(r'account/', include('account.urls', namespace='account')),
