[Answered ]-DJANGO: How to allow Users to change password?

You have a wrong URL pattern defined: Django tries to find testdb.views.django.contrib.auth.views as you define the password_change view inside patterns('testdb.views',.

Add a second pattern:

urlpatterns += patterns('django.contrib.auth.views',
  url(r'^user/(?P<user_id>\d+)/user_edit/password/$', 'password_change')
)

That should resolve your issue.

cfedermann has a solution to your issue, but I’m confused as to why you’ve defined the password_change URL in the first place. This functionality is built-in to the admin, and – like all the other admin pages – the URL is defined already by the admin code itself.
