Is there any way to login to Django admin interface using username or email?
Question:
I want to implement a login system to login to Django admin via email or username. Does anyone know how to implement it. I use custom user model. I know how to allow user to login to website using username or email. But it doesn’t work in Django admin interface
from django.conf import settings
from django.contrib.auth import get_user_model
class EmailOrUsernameModelBackend(object):
def authenticate(self, username=None, password=None):
if '@' in username:
kwargs = {'email': username}
else:
kwargs = {'username': username}
try:
user = get_user_model().objects.get(**kwargs)
if user.check_password(password):
return user
except User.DoesNotExist:
return None
def get_user(self, username):
try:
return get_user_model().objects.get(pk=username)
except get_user_model().DoesNotExist:
return None
Answers:
You need to pass request in the authenticated
method:
from django.conf import settings
from django.contrib.auth import get_user_model
class EmailOrUsernameModelBackend(object):
def authenticate(self, request, username=None, password=None):
if '@' in username:
kwargs = {'email__iexact': username}
else:
kwargs = {'username': username}
try:
user = get_user_model().objects.get(**kwargs)
if user.check_password(password):
return user
except get_user_model().DoesNotExist:
return None
def get_user(self, username):
try:
return get_user_model().objects.get(pk=username)
except get_user_model().DoesNotExist:
return None
Also, make sure to put it in AUTHENTICATION_BACKENDS
:
AUTHENTICATION_BACKENDS = ['path.to.EmailOrUsernameModelBackend']
You could create a custom user manager sub-classing from the UserManager
class and override the get_by_natural_key
method.
from django.contrib.auth.models import UserManager
class UserAccountManager(UserManager):
def get_by_natural_key(self, username):
return self.get(
models.Q(**{self.model.USERNAME_FIELD: username})
| models.Q(**{self.model.EMAIL_FIELD: username})
)
Please note that this will authenticate all users in your system by either email or password and not just on the admin page.
