Today I accidentally ran migrations on a production environment that shouldn't run. Luckily, the table wasn't critical, but it did cause a feature of an app to break.

There is not a straight forward way to "force" a previous migration that already ran via a simple Rake command or something.

Eventually, I found a solution inspired by this post on StackOverflow:

Here's what I did to bring back the table by re-running the previous migration.

$ rails console
irb(main)> require "#{Rails.root.to_s}/db/migrate/20160211142708_create_onboardings.rb"
irb(main)> CreateOnboardings.migrate(:up)
