Creating Migrations

Migrations are easy to setup. Simply create a migration folder (with an __init__.py) and then start creating your migrations.

Migrations require two methods. up for creation and down for deletion.

Peewee has the ability to easily perform migrations such as adding a column. See peewee docs.

You must follow the naming convention x_name where x is a number, and name is a name for your personal reference. This will ensure that migrations are run in the correct order. Here is an example of some migration files:

001_initial.py
002_add_admin_to_users.py
003_add_account_table.py

The basic template for a migration is as follows:

def up:
  pass

def down:
  pass
