Re: Multiple Types of Account with Abstract User

Did you change the AUTH_USER_MODEL setting after you had already run python manage.py migrate once (or more) before? From the error I guess what's happening is that you already have a User model in place. It was probably created when you first ran Django migrations without specifying a custom user model.

If that is the case, and you really want a custom user model, you'll have to ensure that the user model is the first model create in your app. For details look at the warning given at https://docs.djangoproject.com/en/1.10/topics/auth/customizing/#substituting-a-custom-user-model.

From what I'm seeing of your models, you only seem to want to add extra fields to each user. You can also do that by just pointing your UserDetails model to the existing django.contrib.auth.models.User model, and adding the type information in your UserDetails model instead. That might work for you. Otherwise you'll have to remove your existing database and run migrations from start.

Hi,

I am trying to create multiple types of users in my django e-commerce project by extending built-in Django user model but I am having issue.

Would appreciate if someone can guide me to right direction.

Following is the code in my "accounts" app.

from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    type_choices = (
        ('Supplier', 'Supplier'),
        ('Designer', 'Designer'),
        ('Shop', 'Shop'),
        ('Referrer', 'Referrer'),
        ('User', 'User'),
    )
    user_type = models.CharField(max_length=2,
                                 choices=type_choices,
                                 default='User')

class UserDetails(models.Model):
    type = models.OneToOneField(CustomUser)
    extra_info = models.CharField(max_length=200)

My settings.py includes 'accounts' in installed app and variable included for extending models in settings.py:

AUTH_USER_MODEL = 'accounts.Customer'

Error:


ERRORS:
accounts.CustomUser.groups: (fields.E304) Reverse accessor for 'CustomUser.group
s' clashes with reverse accessor for 'User.groups'.
        HINT: Add or change a related_name argument to the definition for 'Custo

sions' clashes with reverse accessor for 'CustomUser.user_permissions'.
        HINT: Add or change a related_name argument to the definition for 'User.
user_permissions' or 'CustomUser.user_permissions'.

Please advise.
