Re: Using email instead of username for registration and login

I opted to customize a little.

First the backend:

from django.contrib.auth.backends import ModelBackend

from django.contrib.auth.models import User

class EmailBackend(ModelBackend):

"""A django.contrib.auth backend that authenticates the user based on its

email address instead of the username.

"""

def authenticate(self, email=None, password=None):

"""Authenticate user using its email address instead of username."""

try:

user = User.objects.get(email=email)

if user.check_password(password):

return user

except User.DoesNotExist:

return None

Then setup settings accordingly (notice that I wrote the backend inside an app called 'accounts'):

AUTHENTICATION_BACKENDS = (

'django.contrib.auth.backends.ModelBackend', # necessary for django.auth

'accounts.backends.EmailBackend' # custom backend to authenticate using the email field

)

And then modify your login view:

if request.method == 'POST' and username and password:

user = auth.authenticate(username=username, password=password)

if user is None:

user = auth.authenticate(email=email, password=password)

What do you think? I know it is not that simple but I couldn't figure out an easier/cleaner way to do it.

Hi all,

I want to use the email address as the username for registration and login.  I'm using django-registration for 2-stage registration.  I'm looking for an easier way than what I've come up with so far.  I can modify registration and activation, but then django.contrib.auth.views.login has a 30-character limit on the username.  I'm not looking forward to making username act like an email address.  Any quick fixes?
