Using Email as login in Django

Question

I am not able to login in django with correct password and email. here is my code.

backends.py

 from django.contrib.auth.models import User

    class Emailbackend(object):

        def authenticate(self, username=None, password=None, **kwargs):
            try:
                user = User.objects.get(email=username)
            except User.MultipleObjectsReturned:
                user = User.objects.filter(email=username).order_by('id').first()
            except User.DoesNotExist:
                return None
            if getattr(user, 'is_active') and user.check_password(password):
                return user
            return None

        def get_user(self, user_id):
            try:
                User.objects.get(pk=user_id)
            except User.DoesNotExist:
                return None

Settings.py

    'users.backends.Emailbackend',
)

Actually, authenticate method expects an argument request should be passed. So you need to declare your Backend like this:

class Emailbackend(object):

    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
        # rest of the code

first check the value of user in authenticate method try block. If it get correct result then check following block what user value return.

if getattr(user, 'is_active') and user.check_password(password):
    return user

If it doesn't work then go to your database and check is your password hash value available or not.

It is not going inside Try – Cipher Dec 26 '18 at 13:19
check which block will execute and what value you get? – shafik Dec 26 '18 at 13:24
It is also not going inside def authenticate – Cipher Dec 26 '18 at 13:25
