That should be all the information needed to fix the problem :)

TL:DR: 

use `{{ protocol }}://{{ domain }}{% url 'user_management:password_reset_confirm' uidb64=uid token=token %}` on line 5 of your email template.

Long answer:

The amount of information you provided last time would have been enough for my gut feeling, which is the same as the tl;dr. But I needed pretty much everything you have given here to be sure :)

The traceback is pretty much useless to finding the origin of the error with template. That's why there is a Template error section. In you case, as you can guess, django try to find a named url but get nothing. To know why, we need to dive into the source and the traceback will be our guide.

Starting with the end, the two last function, _reverse_with_prefix and reverse are internal to django routing. I let them alone.

Next one live in defaulttags and cause issue at a call to reverse. I believe that it's the url template tag. I'm mainly curious about the current_app argument in reverse. I know that url name can take the form "app:name". In your case, that would be "user_management:password_reset_confirm". The current_app argument come from the context property of the tag object [1].

When looking at the traceback, two things stand out for the few followings lines. They all live in the template module and they all have a context argument. So I skip them.

Next stop is send_mail in contrib/auth/forms.py. We get out of the template module but we still have the context argument, which disappear in the following line. Look like a good place to find the value of context.

Oops, look like I was off by one. send_mail take the context argument from save, same file. The call to send_mail taking 4 lines, the context argument have been stripped from the line in the traceback. But the context is defined in the save method [2].

You will notice it's a simple dict without a request key. But if you have looked at how the URL tag define the current_app, you'll notice it make use of the request key of the context.

That's the root of your problem. Email are generated without a request. And without a request, you need to specify the full name of url, as you don't have access to the current_app. By the way, current_app is matching app_name you specify in your URL.py file. That's why I asked the full urls.py the first time.

I hope I'm clear and that will help you :)

All you need to remember is that sometimes, you need to specify the full name of an url.
