Your guide to getting Rails Migrations right.


Do you run migrations with real user data, on a production site where downtime is expensive? Standard migration guides tell you the basics, but not the subtleties. When do you run your migration on your production site? How do you test it?


* Test your migrations, find problems with your real production data

* "The Checklist" for no-downtime deploys with migrations in production

* Migrations without downtime

* Rules for code reviewing migrations

* How-to guides for common operations like changing a column's format


Programmer time, fully loaded, comes to around a hundred bucks an hour. And losing user data makes that look ! Just hit "buy" now. If the book doesn't save you twice its cost in the first sixty days, email me for a refund.
