Answer 1

You have not migrated your models to the database.

If you have created a custom user class, run the below command for creating the migration file .

python manage.py makemigrations

If you have already run the migrations, you need to run the migrate commands so as to convert the migration files into the database schema.

python manage.py migrate

Hopefully, that will solve your problem
