Django can't login the superuser in admin page

Question

So , I am trying to make an register and login system . I want to customize it using the custom user model , where I can save my data and extend the model. I am using AbstractBaseUser and BaseUserManager to do that. The problem is I can't login in the django admin page. I created already a superuser so I can access admin section , I enter the Email and Password correct and then I have this error : "Please enter the correct email and password for a staff account. Note that both fields may be case-sensitive." What my goal is , is that I want to be able to access the administration by login ( i mean fixing this red message and being able to use administration as an superuser ), and then add to the Userr model the specialkey field which will take place in the login view as the username in the built-in django authentication system.

This is the message error : https://i.stack.imgur.com/TL1wT.png.

I hope someone helps me with this , because I can't see the problem in the code , I've been trying to fix this for almost 3 days.

The models.py:

 from django.db import models
 from django.contrib.auth.models import AbstractBaseUser , BaseUserManager



 class UserrManager(BaseUserManager):

def create_user(self , email , username  , password = None):
    if not email:
        raise ValueError ("Users need an email.")
    if not username:
        raise ValueError ("Users need an username")
    #if not specialkey:
     #   raise ValueError ("Users need an specialkey")

    user = self.model(
            email = self.normalize_email(email),
            username = username ,
        )

    user.set_password(password)
    user.save(using = self._db)
    return user

def create_superuser(self , email , username , password ,  ):
    user = self.create_user(
        username = username ,
        email = self.normalize_email(email),
        password = password,

    )
    user.is_staff = True
    user.is_superuser = True
    user.is_active = True

    user.save(using = self._db)
    return user

class Userr(AbstractBaseUser):
    email = models.EmailField(verbose_name='email', max_length = 60 , unique = True)
    username = models.CharField(max_length=30, unique = True)
    date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True)
    last_login = models.DateTimeField(verbose_name='last login', auto_now=True)
    is_admin = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)
    # specialkey = models.CharField(max_length=26 , unique = True)

USERNAME_FIELD = 'email'

REQUIRED_FIELDS = [ 'username' ,   ]

objects = UserrManager()

def __str__ (self):
    return self.username

def has_perm(self, perm, obj=None):
    return self.is_admin

def has_module_perms(self, app_label):
    return True

Answer 1

Had the same issue. Instead of password=None, I changed it to password and passed 'password=password' together with 'username=username' into the create_user functions as you see below:

class MyAccountManager(BaseUserManager): def create_user(self, email, username, password): ....... .......

user = self.model(email=self.normalize_email(
email), username=username, password=password)

    .......

def create_superuser(self, email, username, password):
    user = self.create_user(email=self.normalize_email(
email), username=username, password=password)


    .......

If you still cannot log in, run python manage.py createsuperuser and create a new superuser and try to log in with that one.

Hope it works for you

Answer 2

I would suggest to read this from the Django documentation.

Please confirm that the user is active is_active because if the user is not active you will get the error. I got the same error I forgot to login with user that is active
