Django many-to-many through

migrate executes those SQL commands in the database file . So after executing migrate all the tables of your installed apps are created in your database file.

Migrations are Django’s way of propagating changes you make to your models (adding a field, deleting a model, etc.) into your database schema . They’re designed to be mostly automatic, but you’ll need to know when to make migrations, when to run them, and the common problems you might run into.

Create or update a model. Run ./manage.py makemigrations <app_name> Run ./manage.py migrate to migrate everything or ./manage.py migrate <app_name> to migrate an individual app. Repeat as necessary.
