I completed finish my Django E-commerce web-application. And now I want to add the facility of customer roles(admin,staff,merchant,customer). I’m having problems configuring this with my project. I’d really appreciate if someone can help me through the process. I am sharing the details of project.

My existing Customer model

class Customer(models.Model):
    user=models.OneToOneField(User,on_delete=models.CASCADE)
    # user=models.OneToOneField(User,on_delete=models.CASCADE) -change I made to add CustomUser model
    phone=models.CharField(max_length=10)
    city = models.TextField(max_length=30)
    state = models.TextField(max_length=30)

    def __str__(self):
        return self.user.username

My CustomerUser model that I want to introduce in my project

class CustomUser(AbstractUser):
    ROLES=(
        ('admin', 'Admin'),
        ('staff', 'Staff'),
        ('merchant', 'Merchant'),
        ('user', 'User'),
    )
    role = models.CharField(max_length=8,choices=ROLES,default='Customer')

    def is_admin(self):
        return self.role == 'admin'

    def is_staff(self):
        return self.role == 'staff'

    def is_merchant(self):
        return self.role == 'merchant'

The login, logout and registration stopped working as soon as I added this CustomUser model into my project.
