models.py
```from django.contrib.auth.models import AbstractUser
# from django.db import models


class User(AbstractUser):
    pass

I have attached my github repo here: https://github.com/rlopxhan21/-Blog Code with error is in AbstarctSUerError branch. Thanks

I tried to create whole new app with just abstract user, it worked. But couldn't figure out in this app.

`ValueError: Related model 'useraccount.user' cannot be resolved`, should it be `useraccount.User`, with uppercase U instead of `useraccount.user` with lowercase u? Check your project `settings.py` — whoami, Jan 11 '23 at 08:34

Running the command python manage.py makemigrations accepts the order in executing the migrations like this: python manage.py makemigrations useraccount

Due to limitations of Django’s dynamic dependency feature for swappable models, the model referenced by AUTH_USER_MODEL must be created in the first migration of its app (usually called 0001_initial); otherwise, you’ll have dependency issues.

You should do the migration of your Usermodel first. Read here if you are unable to drop the database. Here you will also find the text of above Quotation. Read here if you can launch the entire database with all its migrations again.

Glad I could help. Please accept it as the correct answer to your question here in stackoverflow. — Tarquinius, Jan 12 '23 at 10:12
