Django добавляет ошибку related_name в пользовательской модели AbstractUser

Question

Django показывает эту ошибку при миграции

SystemCheckError: System check identified some issues:

Предлагается добавить related_name, но у меня нет поля ForeignKey в моей модели, моя модель наследуется от AbstractUser

models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.

class CustomUser(AbstractUser):
    USER_TYPE_CHOICES = (
        (1, 'CUSTOMER'),
        (2, 'AGENT'),
        (3, 'SUPERVISOR'),
    )
    user_type = models.PositiveSmallIntegerField(choices=USER_TYPE_CHOICES)

Answer 1

Добавьте AUTH_USER_MODEL в свою settings.py пользовательскую модель пользователя как

AUTH_USER_MODEL = 'your_app_name.CustomUser'
