You've spent the last few weeks working on this brand new feature for your fancy website and it looks amazing! You and your peers thoroughly tested everything, so it's time to deploy this feature to production. You deploy your project with the Fork CMS Capistrano gem and everything seems to go well.
When checking the production website you suddenly encounter a 500 error! Not sure what went wrong, you quickly revert your feature and deploy again. All is well... You import the production database to your local system and start debugging, only to find out you forgot to add that database field you added a week ago.
