I am trying to use email for authenication in Django. In other words I am extending django authentication. I followed all the steps and trust me it worked before. Now it stopped working.
this is model.py
from django.db import models
from django.contrib.auth.models import AbstractBaseUser,BaseUserManager,PermissionsMixin
from django.core.mail import send_mail

this is manager.py
from models import CustomUser
class CustomUserAuth(object):
def authenticate(self, username = None, password =None):
try:
user =CustomUser.objects.get(email=username)
if user.check_password(password):
return user
except CustomUser.DoesNotExist:
return None
def get_user(self, user_id):
try:
user=CustomUser.objects.get(pk=user_id)
if user.is_active:
return user
return None
except CustomUser.DoesNotExist:
return None
I have included following lines in my settings.py file
AUTH_USER_MODEL = 'user_management.CustomUser'
AUTHENTICATION_BACKENDS = ('user_management.manager.CustomUserAuth',)
now for troubleshooting I ran python manage.py shell and import the form
CustomUserCreationForm and passed the data to it and tried to save it. I got the same error
error trace back

There is much info about the following error. I tried to google but I found one bug in django 1.5 for which ticket is closed. Few smart people said I used get_user_model but those information is incomplete.
Please help
AUTHENTICATION_BACKENDSinstead of using a custom user model. Please refer to this question if you want email login: stackoverflow.com/questions/37332190/django-login-with-email – Jaskaran Singh
