Django: password reset ReverseMatch error

Question

I'm having trouble getting password_reset_confirm to work. I have looked at numerous solutions, but none seem to be working for me.

urls.py: (in particular, the third line)

(r'^resetpassword/passwordsent/$', 'django.contrib.auth.views.password_reset_done', name="reset_password"),
(r'^resetpassword/$', 'django.contrib.auth.views.password_reset', name="reset_password"),
(r'^reset/(?P<uidb64>[0-9A-Za-z_\-]+)-(?P<token>,+)/$', 'django.contrib.auth.views.password_reset_confirm'),
(r'^reset/done/$', 'django.contrib.auth.views.password_reset_complete'),

the password_reset_email.html:

{% load url from future %}
{% autoescape off %}
Someone asked for password reset for email {{ email }}. Follow the link below:
{{ protocol}}://{{ domain }}{% url 'django.contrib.auth.views.password_reset_confirm' uidb64=uid token=token %}
{% endautoescape %}

Everything seems to be working fine, until I submit my e-mail and get the following error:

Reverse for 'django.contrib.auth.views.password_reset_confirm' with arguments '()' and keyword arguments '{u'uidb64': 'OQ', u'token': u'3n2-0fee9d3f98dad36e63d8'}' not found. 2 pattern(s) tried: ['/$reset/(?P<uidb64>[0-9A-Za-z_\\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', 'reset/(?P<uidb64>[0-9A-Za-z_\\-]+)-(?P<token>,+)/$']

I am using Django 1.6. Any help is much appreciated! Thanks!

Yes I have, I changed my url conf to be the full path, but it still hasn't worked for me. — user1670032, Dec 02 '13 at 02:06

You can see from the exception what's going on, although it's a little hard to spot. If you look at what patterns it tried:

2 pattern(s) tried: ['/$reset/(?P<uidb64>[0-9A-Za-z_\\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', 'reset/(?P<uidb64>[0-9A-Za-z_\\-]+)-(?P<token>,+)/$']

You should notice that the first pattern is the one that should generally match, in the sense that it accepts a token with a - in it. But it has a stray $ prepending the rest of its content, so actually it can't match anything:

'/$reset/...'

You don't show the urls.py line that establishes that pattern - the third line you refer to can only match a token consisting of nothing but commas:

(?P<token>,+)

So while I can safely say that you need to correct your urls.py, I cannot say exactly where you need to correct it. If you intend to match that urls.py line, you should update the token group regexp to accept your actual token values, and should figure out why the other one is around to match at all. That said, if - is a valid character to appear as part of your token I think you'll find it easier overall to use / as a divider between your uidb64 field and your token, as your first regexp does except for the stray $.
