Django change_password NoReverseMatch at /accounts/password/change/

Question

I have the following url config in accounts/urls.py:

url(r'^password/change/$', 'django.contrib.auth.views.password_change',
{'template_name': 'change_password.html'}, name='password_change'),
url(r'^password/change/done/$', 'django.contrib.auth.views.logout_then_login',
name='password_change_done'),

But if I call the password-change url I get the following

error: NoReverseMatch at /accounts/password/change/ Reverse for 'password_change_done' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

If the user modified his password, it is to be logged out and login again.

Thanks a lot.

Looks like it did not try any patterns. Can you show the root url conf ? — karthikr, Oct 04 '14 at 20:14
in the root url: url(r'^accounts/', include('accounts.urls', namespace='accounts'), name='account'), — user1644033, Oct 04 '14 at 20:21
Try changing `name='password-change-done'` to `name='password_change_done'` in your accounts/urls.py. — Anton Strogonoff, Oct 04 '14 at 20:22
In that case let's take a look at your full traceback) (with line numbers) — Anton Strogonoff, Oct 04 '14 at 20:29
How are you adding `accounts/urls.py` to your main `urls.py`? — Burhan Khalid, Oct 04 '14 at 20:38
in the root url: url(r'^accounts/', include('accounts.urls', namespace='accounts'), name='account'), — user1644033, Oct 04 '14 at 20:40
Can you paste the `views.py` code? It is saying that it is trying to redirect, but can't. — Aaron Lelevier, Oct 04 '14 at 20:42
rly? its the default django password_change view in: .../lib/python3.4/site-packages/django/contrib/auth/views.py — user1644033, Oct 04 '14 at 20:46
As it's namespaced, have you tried reversing 'accounts:password_change_done' ? — Ben, Oct 04 '14 at 21:50
I have: 'accounts:password_change' because it call the default django view to change password(old, new, new - password). The password_change template called: 'accounts:password_change' in form post. I only have a different template... for change passwords. — user1644033, Oct 05 '14 at 12:42

One of the references to 'password-change-done' has dashes, the other has underscores. It's likely something to do with that!

I realize that this is a very old question, but I had the same error yesterday. I think the namespace is the problem. Once you've namespaced the urls, they'll all need to be prefixed with the name of the namespace (in your case "accounts") and a colon. If you look at the code for the password_change view, it (conditionally) redirects based on a url of 'password_change_done'. Because that url hasn't been decorated with your namespace, it can't be found. Drop the namespace, ensure that your url references no longer have it and you should be OK.
