How to add user types in groups in Django?

Question

I rewrote the User Django model for CustomUser using AbstractUSer adding two booleans, such as is_admin and is_insurer.

Moreover, two groups were created programmatically: admin_group and insurer_group each with their respective permissions. I am trying to add each group to user type.

In the case:

1 - CustomUser.is_admin equal to admin_group,

2 - CustomUser.is_insurer equal to insurer_group

So as soon as I add the user type, ex: is_admin for True, this user has access to admin_group.

I’m trying this way:

py.models:

from django.db import models
from django.contrib.auth.models import AbstractUser, Group, Permission
from django.contrib.contenttypes.models import ContentType

class CustomUser(AbstractUser):
    is_admin = models.BooleanField(default=False)
    is_insurer = models.BooleanField(default=False)



    @property
    def insurer(self):
        insurer_group = Group.objects.get(name='insurer_group')
        self.is_insurer.groups.add(insurer_group)

    @property
    def admin(self):
        admin_group = Group.objects.get(name='admin_group')
        self.is_admin.groups.add(insurer_group)

    def __str__(self):
        return self.username

But I’m getting error:

maximum recursion depth exceeded while calling a Python object

I have tried passing the permission directly on the Customuser model however it will not.
