DB Setup
Ensure db engine configuration in the <appname>/settings.py file.
Then, run python manage.py migrate to run the initial migration for system apps.
Adding Models to the DB
For each app that uses a db model, once it is ready to be included in migrations, ensure it is listed under INSTALLED_APPS in the settings.py conf.
Run python manage.py makemigrations <appname> to scan the models for that app and create any migrations based on the diff.
Run python manage.py sqlmigrate <appname> <migrationN> to get a preview of the sql commands autogenerated from that migration.
