How do I configure Django's auth user model to have a UUID (Postgres DB)

Question

I'm using Python 3.9 and Django 3.2. Here is my folder structure

+ cbapp
    - settings.py
    + models
        - __init__.py
        - custom_user.py
- manage.py

Here's what my customer_user.py file looks like

$ cat models/custom_user.py
import uuid

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


class CustomUser(AbstractUser):
    pass
    uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)

Additionally, I have configured this in my settings.py file

AUTH_USER_MODEL = 'models.CustomUser'

However, when I run "python manage.py makemigrations", I get this error

django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'models.CustomUser' that has not been installed

I have no idea what this means. I have this in my settings.py file

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'cbapp',
]
...
AUTH_USER_MODEL = 'models.CustomUser'

Seems like your module that containing the models that didn't initialize during the Django startup. — JPG

According to Django doc, to substitute a custom User model

You create your custom user model ( you did it already )
In settings.py, point AUTH_USER_MODEL to it ( the model, you create above ) like this:
```
 AUTH_USER_MODEL = 'myapp.MyUser'
```
You error is here : instead of AUTH_USER_MODEL = 'models.CustomUser' write AUTH_USER_MODEL = 'cbapp.CustomUser'

NB : Don't point your models file but your app_name then the model_name.
