You should not manually change schema.rb, you should instead write a migration to change the database design. Running the migration will update schema.rb. See the Rails Guide on Migrations for how to do this. In order to put schema.rb back to what it should be before running the migrations you can do rake db:schema:dump You can alternatively just revert schema.rb using your Version Control System. If you are not using a VCS then start doing so immediately, you will not regret it. I prefer git. I assume you are just getting started with Rails so have a look at all the Rails Guides and work through some tutorials. Make sure you are using Rails 3 and that the tutorial is for this version. railstutorial.org is good and is free to use online.
