What’s the “proper” way to do this in Rails?

It sort of depends on when this happened in your development cycle, If you recently made the change and haven’t pushed it out into a public repo, then you indeed might want to do the rollback thing and then edit the migration files and migrate again, just to keep things clean. But if it’s a change to a migration that’s a few migrations back then you should create a new migration that changes the rows and columns to the “new” old values.
