Peewee Migrate 2 -- A simple migration engine for Peewee
Contents
It's a fork of original https://github.com/klen/peewee_migrate. Thank klen for that!
But klen don't support project for a long time.
To fix critical issues project was forked and development continued.
All previous compatibilities will be preserved.
- python 2.7,3.5
- peewee >= 3.3.1
For Peewee<3.0 please use Peewee-Migrate==0.14.0.
To reduce code changes Python package name don't changed. Only name on PyPI.
If you have installed previous version please remove it before using pip:
pip uninstall peewee_migrate
Peewee Migrate should be installed using pip:
pip install peewee_migrate2
Do you want Flask integration? Look at Flask-PW.

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