Custom class `AppUser` breaks command `./manage.py createsuperuser`, users cannot log into `admin`

[paulrogov]

Steps to reproduce:

./manage.py createsuperuser
email: [email protected]
username: joe
password: abc321
password: abc321

When trying to log in:

Solution:

1. Add two Boolean fields to the AppUser:

class AppUser(AbstractBaseUser, PermissionsMixin):
	user_id = models.AutoField(primary_key=True)
	email = models.EmailField(max_length=50, unique=True)
	username = models.CharField(max_length=50)

	is_staff = models.BooleanField(default=False)
	is_superuser = models.BooleanField(default=False)

	USERNAME_FIELD = 'email'
	
	objects = AppUserManager()

	def __str__(self) -> str:
		return self.username

2. Fix create_superuser() method:

class AppUserManager(BaseUserManager):
	def create_superuser(self, email, password=None, **extra_fields):
		if not email:
			raise ValueError('An email is required')
		if not password:
			raise ValueError('A password is required')
		user = self.create_user(email, password)
		user.is_staff = True
		user.is_superuser = True
		user.save()
		return user
