This is what the status of my migrations look like. Any idea how I can remove the two no files? The traditional rake:db:rollback throws an error, which is expected.
Alt. can someone explain to me how I would return to a previous version of my code from github? I've been committing my changes regularly.

SOLUTION: I was looking for something like rake db:reset
