You can usually fix it by running “git checkout db/&& rake db:reset && rake db:migrate”. When I was first introduced to branched databases, rainbows appeared, unicorns flew through the air, all those songs on the radio suddenly made sense, and Clarence Odbody from finally got his wings.
In your development and testing environments each git branch should have its own isolated database.
Most have relied on storing DDL in revision control, ever vigilant to ensure that our database creation scripts are updated and consistent with each rollout.
That solution can be very clumsy in an Extreme Programming project.
The diff you should see is the change made by your migration(s).
Whenever you commit a migration, commit the changes in as well. A commit’s code “state” and schema “state” should always match.There's probably as many ways to manage a schema for a project as there are open source content management systems.What most developers end up settling on is some sort of combination of ongoing database creation scripts and data load scripts written in pure SQL. Rails’ database schema and migration management is still one of the things that sets it apart from other frameworks.That said, if you don’t use the tools exactly as intended, you’ll be pounding your fist on your desk and stabbing yourself in the eye. Below I’ve compiled some notes about Rails migration etiquette and best-practices that I’ve discovered or been taught over the years.
Migrations are for transforming the database from one point in history (commit) to another.
