I do not know what I'm doing wrong look at my model.py I'm using a User extending AbstractBaseUser since I wanted to use the email field as an identifier and not the username that comes with the default in fact delete it. Using the admin works perfect but when I want to use forms to create a student type user gives me this error:
django.db.utils.IntegrityError: NOT NULL constraint failed: account_estudianteperfil.anno_id
