annotate wiki/signals.py @ 752:95f4e7f352fd
For Django 1.6: contrib auth password reset confirm view signature changed.
The uidb64 parameter was previously base 36 encoded and named uidb36.
Had to update urls.py. While I was in there I decided to make the
password reset email use the {% url %} tag to be more resilient if the
url changes.
