I want django to authenticate users via email, not via usernames. One way can be providing email value as username value, but I dont want that. Reason being, I've a url /profile/<username>/
, hence I cannot have a url /profile/[email protected]/
.
Another reason being that all emails are unique, but it happen sometimes that the username is already being taken. Hence I'm auto-creating the username as fullName_ID
.
How can I just change let Django authenticate with email?
This is how I create a user.
username = `abcd28` user_email = `[email protected]` user = User.objects.create_user(username, user_email, user_pass)
This is how I login.
email = request.POST['email'] password = request.POST['password'] username = User.objects.get(email=email.lower()).username user = authenticate(username=username, password=password) login(request, user)
Is there any other of of login apart from getting the username first?
from django.contrib.auth import authenticate, login def my_view(request): username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) # Redirect to a success page. ... else: # Return an 'invalid ...
You should write a custom authentication backend. Something like this will work:
from django.contrib.auth import get_user_model from django.contrib.auth.backends import ModelBackend class EmailBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): UserModel = get_user_model() try: user = UserModel.objects.get(email=username) except UserModel.DoesNotExist: return None else: if user.check_password(password): return user return None
Then, set that backend as your auth backend in your settings:
AUTHENTICATION_BACKENDS = ['path.to.auth.module.EmailBackend']
Updated. Inherit from ModelBackend
as it implements methods like get_user()
already.
