I made a custom user model and added some authentication system, but when I try to login into my account, it won't let me, but if I change the password to all lowercase, then it lets me login.
I added this custom backend because the email field was case-sensitive, and I didn't want that, and now it messes up my login system.
backends.py
from django.contrib.auth import get_user_model
from django.contrib.auth.backends import ModelBackend, UserModel
class CaseInsensitiveModelBackend(ModelBackend):
def authenticate(self, request, username=None, password=None, **kwargs):
UserModel = get_user_model()
if username is None:
username = kwargs.get(UserModel.USERNAME_FIELD)
try:
case_insensitive_username_field = '{}__iexact'.format(UserModel.USERNAME_FIELD)
user = UserModel._default_manager.get(**{case_insensitive_username_field: username})
except UserModel.DoesNotExist:
UserModel().set_password(password)
else:
if user.check_password(password) and self.user_can_authenticate(user):
return user

If anyone can help me, it'd mean a lot.
If I should provide and more files, please let me know.
