You need to write a manager for a custom user model [Django-doc] to reimplement the create_user method.

You can thus implement a CustomUserManager:

from django.contrib.auth.hashers import make_password
from django.contrib.auth.models import UserManager

class CustomUserManager(UserManager):

    def _create_user(self, email, password, **extra_fields):
        email = self.normalize_email(email)
        user = CustomUser(email=email, **extra_fields)
        user.password = make_password(password)
        user.save(using=self._db)
        return user

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

    def create_superuser(self, email, password=None, **extra_fields):
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        assert extra_fields['is_staff']
        assert extra_fields['is_superuser']
        return self._create_user(email, password, **extra_fields)

class CustomUser(AbstractUser):
    # …

    objects = CustomUserManager()

and then you register this manager thus as the objects manager.
