Django default password_change ne fonctionne plus?

Question

J'essaie d'user django intégré auth vues pour ajouter change password fonction.

Je crée l'application nommée 'utilisateurs' et configurer urls.py comme ci-dessous:

Et je crée aussi users/password_change_form.html, users/password_change_done.html aussi.

Mais il se produit une erreur:

besoin de votre aide. Merci :)

Answer 1

Le problème est que vous avez spécifié un app_name en haut de votre configuration d'URL. Cela signifie que toutes les URL que vous définissez sont nommées avec app_name. Le nom final de l'URL de changement de mot de passe est users:password_change_done et non password_change_done. C'est pourquoi la recherche inversée échoue.

Vous pouvez corriger cela en passant un post_change_redirect kwarg à la vue password_change:

from django.core.urlresolvers import reverse 

url(
    r'^password_change/$', 
    password_change, 
    name='password_change', 
    kwargs={ 
     'template_name': 'users/password_change_form.html', 
     'current_app':'users', 
     'post_change_redirect': reverse_lazy('users:password_change_done') 
    } 
), 

Notez également que l'argument est current_appdeprecated depuis Django 1.9:

The current_app parameter is deprecated and will be removed in Django 2.0. Callers should set request.current_app instead.
