This was a big help. Thanks! One thing though: I couldn't get the newly created migration file to work initially. I kept getting an error that said "uninitialized constant CreateDatabase." I had to rename the migration class "CreateDataBase".
So the first line of the migration file is now: class CreateDatabase < ActiveRecord::Migration Everything looks good now.
