Depends. If you haven't yet run rake db:migrate, you can just edit the migration, but you need to know what you're doing if it's complex. If you've already migrated, and you've used any new columns or tables you've added, then you must create another migration. If you've migrated but not used the new columns or tables, and it's a migration that CAN be rolled back (not all can), you *can* roll it back (rake db:rollback), fix it, and re-migrate... but you must be *very* certain that your rollback won't lose you any data. -Dave -- Dave Aronson: Available Cleared Ruby on Rails Freelancer (NoVa/DC/Remote) -- see www.DaveAronson.com, and blogs at www.Codosaur.us, www.Dare2XL.com, www.RecruitingRants.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
