From python
-----------

.. code-block:: python

    from peewee_migrate import Router
    from peewee import SqliteDatabase

    router = Router(SqliteDatabase('test.db'))

    # Create migration
    router.create('migration_name')

    # Run migration/migrations
    router.run('migration_name')

    # Run all unapplied migrations
    router.run()

Migration files
---------------

By default, migration files are looked up in ``os.getcwd()/migrations`` directory, but custom directory can be given.

Migration files are sorted and applied in ascending order per their filename.

Each migration file must specify ``migrate()`` function and may specify ``rollback()`` function

.. code-block:: python

    def migrate(migrator, database, fake=False, **kwargs):
        pass

    def rollback(migrator, database, fake=False, **kwargs):
        pass
