Below is my custom user model:
class CUserManager(BaseUserManager):
def _create_user(self, email, first_name, password,
is_staff, is_superuser, **extra_fields):
"""
Creates and saves a User with the given email and password.
"""
now = timezone.now()
if not email:
raise ValueError('The given email must be set')
email = self.normalize_email(email)
user = self.model(email=email,
first_name = first_name,
is_staff=is_staff, is_active=False,
is_superuser=is_superuser, last_login=now,
date_joined=now, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email, first_name, password=None, **extra_fields):
return self._create_user(email, first_name, password, False, False,
**extra_fields)
def create_superuser(self, email, first_name, password, **extra_fields):
return self._create_user(email, first_name, password, True, True,
**extra_fields)
class CUser(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(_('email address'), max_length=254, unique=True)
first_name = models.CharField(_('first name'), max_length=30)
last_name = models.CharField(_('last name'), max_length=30, blank=True)
is_staff = models.BooleanField(_('staff status'), default=False,
help_text=_('Designates whether the user can log into this admin '
'site.'))
is_active = models.BooleanField(_('active'), default=False,
help_text=_('Designates whether this user should be treated as '
'active. Unselect this instead of deleting accounts.'))
date_joined = models.DateTimeField(_('date joined'), default=timezone.now)
last_updated = models.DateTimeField(_('last updated'), default=timezone.now)
objects = CUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['first_name', 'last_name']
It creates a new user correctly. But when I try to authenticate the user from shell or from views, the authenticate() function doesn't work for users having is_active=False
.
>>> from django.contrib.auth import get_user_model, auhtenticate
>>> u = get_user_model()
>>> authenticate(username='abc@gmail.com', password='abc)
The above line returns nothing if the user is inactive but returns the user object otherwise. I don't understand why its returning nothing for inactive users.
It is happening because of how django's authentication works. By default it uses ModelBackend
which checks for is_active
https://docs.djangoproject.com/en/1.10/ref/contrib/auth/#django.contrib.auth.backends.ModelBackend.get_user_permissions
So you can create custom authentication backend which will ignore this option https://docs.djangoproject.com/en/1.10/topics/auth/customizing/#writing-an-authentication-backend
Hi You can write Custom backend for this problem.
from django.contrib.auth.hashers import check_password
from django.contrib.auth.models import User
from apps.staffs.models import Staff(Custom User)
class StaffBackend:
# Create an authentication method
# This is called by the standard Django login procedure
def authenticate(self, username=None, password=None):
try:
# Try to find a user matching your username
user = Staff.objects.get(username=username)
# Check the password is the reverse of the username
if check_password(password, user.password):
# Yes? return the Django user object
return user
else:
# No? return None - triggers default login failed
return None
except Staff.DoesNotExist:
# No user was found, return None - triggers default login failed
return None
# Required for your backend to work properly - unchanged in most scenarios
def get_user(self, user_id):
try:
return Staff.objects.get(pk=user_id)
except Staff.DoesNotExist:
return None
