If you're using eclipse IDE, you can leverage the templates to write a migration script in no time.
Go to windows -> preferences -> PyDev -> Editor -> Templates
then create a new template with :
- name : Module: Migration SQLA
- context: New Module
- description: SQLA migration
# -*- coding: utf-8 -*- ''' Created on ${date} @author: ${user} ''' from sqlalchemy import * from migrate import * meta = MetaData() def upgrade(migrate_engine): meta.bind = migrate_engine some = Table('some', meta, autoload=True) if not 'somename' in some.columns: new_col = Column('somename', Unicode(255)) new_col.create(some) ${cursor} def downgrade(migrate_engine): meta.bind = migrate_engine some = Table('some', meta, autoload=True) some.c.some_col.drop()
And that's it ! you can now go into your migrations folder and do:
New -> PyDev Module, and choose your new template
Just to note, you could use ${somename} and ${some} as variables.
