run
python manage.py migrate
if you want to specify the migration you can. Just roll back one and then run migrate again to test the current migration
whenever the schema changes so that your local database follows the new schema
Also make sure to use Django to create a migration every time you change the schema for a PR
Create a Migration
% python manage.py makemigrations atsaccounts --empty
Run a migration back to something
python manage.py migrate atsaccounts (NUMBER)
will run the reverse migrations to get you to that version.
Django Python Class ⇒ Django ORM ⇒ SQL Database
The schema of the database might not match what you wrote in the python class. Thus we need migration files to match that up.
