Django - Read The Current's User Authentication Backend Class

I am using a custom authentication backend with Django, to automatically create and login users from a legacy system. My Backend class is this: from django.contrib.auth.backends im

Solution 1:

The backend attribute is added to the user object when the user authenticates using the django.contrib.auth.authenticate(username='foo',password='bar') function.

This function in turn calls all of the AUTHENTICATION_BACKENDS you have specified in your settings.py file, until it is able to authenticate successfully using one of them.

If your users are "logged in" but don't have a backend attribute that probably means you're not properly authenticating them. Maybe you're calling your SFIUserBackend.authenticate function directly, when you should be calling the django.contrib.auth.authenticate function?

Check out these custom authentication docs.

Solution 2:

You should read it in the the view and send an appropriate human form of that class name as the message.

Solution 3:

While authenticate() adds the user.backend attribute and login() saves it in the session, for some reason get_user() does not add it back to the user. I have submitted a patch.

Therefore, in order to access it in another request, you need request.session[django.contrib.auth.BACKEND_SESSION_KEY].

You can also write a custom tag or add it to your context (under whatever name you want) for ease of use.
