Sorry to hear you had a bad experience. The auto-migration support in Sails is a development-only feature, but for production, there is a great project from Danni Friedland called sails-migrations: https://github.com/BlueHotDog/sails-migrations

You might also want to check out sails-db-migrate: https://github.com/building5/sails-db-migrate

At Treeline, we're using sails-migrations in production.
