Engine Yard rollback a migration

Question

I deployed a new feature to Engine Yard that had migrations. Of course I passed the migration flag and it worked successfully. But then I decided to take the feature out.

Note: These migrations removed some columns

I then rolled back on github and deployed again, but now I'm getting a postgres error that a column doesn't exist (this is a column removed in the migration from before)

How do you rollback migrations on Engine Yard?

TMP,

While there is a rollback command built into the engineyard gem, it would be better to just deploy with a new migration that effectively adds the columns back in or update the code to not use the missing columns.

that seems inefficient though. i've seen things about the rollback command but that doesn't handle it. it's odd you can't just rollback migrations – Tom Prats Oct 09 '13 at 04:45

I've discovered that when you ssh into your engineyard app you can go to the current deploy's directory and run bundle exec rake ... thus you can run probably run bundle exec rake db:rollback
