Answer 1

Add these codes to your model.py

1. Import PermissionsMixin from Django contrib Auth

   from django.contrib.auth.models import PermissionsMixin
   

2. Then change

   class Account(AbstractBaseUser):
   
    to
   
   class Account(AbstractBaseUser, PermissionsMixin):
   

Then it will work fine

Answer 2

Instead of returning self.is_superuser, return self.is_admin

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

def has_module_perms(self, app_label):
            return self.is_admin

will work I hope. :-) It's been one and half a year.
