"no such table" exception

In Django I added models into models.py. After manage.py makemigrations, manage.py migrate raised this exception:

django.db.utils.OperationalError: no such table: auth_test_usertranslatorprofile

I removed all old migrations and run makemigrations and migrate again which seemed to work. It didn't help because when I click User customer profiles of User translator profiles it raises exception:

What is the problem?

I solved the same problem with these steps :

• Delete your database (db.sqlite3 in my case) in your project directory
• Remove everything from __pycache__ folder under your project subdirectory
• For the application you are trying to fix, go to the folder and clear migrations and __pycache__ directories

When you are sure you have cleared all the above files, run:

python manage.py makemigrations
python manage.py migrate
