[Python] i got TypeError: UserManager.create_superuser() missing 1 required positional...

I want to create super user just from email and password so it should create super user without username. I am using custom user model and when i try to create superuser i got this error TypeError: UserManager.create_superuser() missing 1 required positional argument: 'username'

This is my manager.py file

from django.contrib.auth.base_user import BaseUserManager


class UserManager(BaseUserManager):
use_in_migrations = True

def _create_user(self, email, password, **extra_fields):

if not email:
raise ValueError('The given email must be set')
email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user

def create_user(self, email, password=None, **extra_fields):
extra_fields.setdefault('is_superuser', False)
return self._create_user(email, password, **extra_fields)

def create_superuser(self, email, password, **extra_fields):
extra_fields.setdefault('is_superuser', True)
extra_fields.setdefault('is_staff', True)

if extra_fields.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')
if extra_fields.get('is_staff') is not True:
raise ValueError('Superuser must have is_staff=True')

return self._create_user(email, password, **extra_fields)


This is my models.py

class User(AbstractUser)
"""
Abstract User of django auth user model.
"""
uuid = models.UUIDField(default=uuid.uuid4, unique=True, null=False)
email = models.EmailField(_("email address"), unique=True)
middle_name = models.CharField(max_length=120, blank=True)
image = models.ImageField(upload_to='user_profile/', blank=True)
department = models.CharField(blank=True, choices=Department.choices,
max_length=2)
designation = models.CharField(max_length=120, blank=True)
last_logout = models.DateTimeField(null=True)
is_superuser = models.BooleanField(default=False)
view = models.TextField(blank=True)

USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
