As the command line output says the problem is that you changed the models. The solution is to run python manage.py makemigrations and then python manage.py migrate.

The Best Thing You can do is, Delete the existing database. In my case, I were using phpMyAdmin SQL database, so I manually delete the created database overthere. Again run the following Commands:

python manage.py makemigrations

python manage.py migrate

python manage.py makemigrations <app_name>

python manage.py migrate

IT COULD BE BECAUSE YOU HAVE NOT YET REGISTERED YOUR APP IN SETTINGS.PY inside this file install your app (put the name of your app in quotes) after you can make python3 manage.py makemigrations and then python3 manage.py migrate (it can be python3 or python without the 3 ):

INSTALLED_APPS = [
     'django.contrib.admin',
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     'new_app_name',
]

Hi my friend after all these steps if there was still this problem.

1- Clear all tables in the database.

2-Clear all history in the migrations folder of your project directory.

3-python manage.py makemigrations

4-python manage.py migrate
