Anonymous user has no attribute _meta in custom user model - django

Question

I've been facing this problem for so long now and I'm done experimenting. I'm a newbie in Django.
I've been using a custom user model but for some reason this Registration form doesn't work properly. I can't login using the method login(), though it'saving the data fine. Also, the login form doesn't allow any other user login other than the superuser.
Here is the error:

Answer 1

You're not saving the password for the user. Your custom RegisterForm is a ModelForm for CustomUser that only saves the fields email and name.
So when you authenticate() your user, this fails and returns None.
Your next step is to login() the user, which is None and produces the error you see.
Inherit from django.contrib.auth.forms.UserCreationForm instead of ModelForm. That will spare you a lot of code (e.g. you don't have to define the password1 and password2 fields, nor clean_password2) and correctly save your user.
