hi, @brutasse

I met a problem, and could not find an answer through google or the docs, so that I've to disturb you.

Django: 1.10.1
Python: 3.5.2

When a user tries to reset password, it throws exception:

NoReverseMatch at /pwd_reset/recover/
Reverse for 'password_reset_reset' with arguments '('NQ:1dYOiG:BKXR_HhymHf7uYTnlDcPHioITOY',)' and keyword arguments '{}' not found. 0 pattern(s) tried: []

codes:

settings.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog',
    'account',
    'password_reset',
]

urls.py

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^blog/', include('blog.urls', namespace='blog', app_name='blog')),
    url(r'^account/', include('account.urls', namespace='account', app_name='account')),
    url(r'^pwd_reset/', include('password_reset.urls', namespace='pwd_reset', app_name='pwd_reset')),
]

I followed the documentation and wrote the codes above in the project's root settings and urls file.

When I visited the url http://127.0.0.1:8000/pwd_reset/recover/ and submitted a username, then an exception came.

Thank you!

OK, I found what happened.

url(r'^pwd_reset/', include('password_reset.urls', namespace='pwd_reset', app_name='pwd_reset')),

should be

url(r'^pwd_reset/', include('password_reset.urls')),

But, what caused this question is still a little bit confused：
when I use namespace and app_name, then the template is {% url "pwd_reset:password_reset_reset" token %}. Same exception again.

I had the same problem, just use a relative URL instead {% url "pwd_reset:password_reset_reset" %} something like this:
<p><a class="forget" href="../../recover/">¿Olvidaste la contraseña?</a></p>
And in your main urls.py
url(r'^/', include('password_reset.urls')),
