Create DB : python manage.py migrate

The migrate command takes all the migrations that haven’t been applied (Django tracks which ones are applied using a special table in your database called django_migrations) and runs them against your database - essentially, synchronizing the changes you made to your models with the schema in the database.

Update DB: python manage.py makemigrations

By running makemigrations, you’re telling Django that you’ve made some changes to your models (in this case, you’ve made new ones) and that you’d like the changes to be stored as a migration.

The three-step guide to making model changes:

1. Change your models (in models.py).
2. Run python manage.py makemigrations to create migrations for those changes
3. Run python manage.py migrate to apply those changes to the database.
