rake db:rollback_to_common
If you find yourself having to switch locally between different git branches that have different database schemata, (for instance, a master branch and a production branch), one of the biggest hassles is keeping the database in the right state. We wrote this rake task to make the process painless: just specify the branch you’re about to switch to, and it will automatically roll back to the last common database version between that and your current branch. Usage:
rake db:rollback_to_common branch=production git checkout -m productionIt will raise an exception if nothing needs to be done, which doesn’t really bother me, but if it bothers you, feel free to edit - it’s a gist.
