class UserManager(BaseUserManager):
def create_user(self,phone, password=None,is_staff=False,is_admin=False,is_active=True):
if phone is None:
raise TypeError('Users must have a phonenumber.')
user = self.model(phone=phone)
user.set_password(password)
user.staff=is_staff
user.admin=is_admin
user.active=is_active
user.save(using=self._db)
return user

# user.staff = True
user.save(using=self._db)
return users

Below is code of serializer.py

)
token = serializers.CharField(max_length=255, read_only=True)
