title: (Rails) Heroku deployments looks for controller that no longer exists
body: <p>Hey I am trying to deploy my rails app on Heroku, but I receive and error code 10 (app crashed) every  time. When I run the "heroku run bundle exec rails console" command, I can see that it's looking for a controller that I deleted long ago and don't rely anymore, why is this and how can I fix it? Much appreciated!</p>
  
  <p>This is the error, it looks for "items_controller" even though I deleted that file weeks ago and my app works in local</p>
