Passing commands to deployed Ruby on Rails App in Bluemix

Finally, with the help of SO member, JeffSloyer, I was able to deploy my RoR app on to bluemix. There seems to be an additional problem with the RoR app. I cant login as admin in this app.

http://csw-events.mybluemix.net/sign_in

The question here is not about the app itself, I have found a solution from the forum dedicated to this RoR app(Currently, in-active) -> SOLUTION.

The question is 1: Can I pass commands to an already deployed app on Bluemix using CF something like this 

 cf -c "User.last.update_attribute(:admin, true)"

If not, What are the alternatives for passing such commands

As for this eg it is 

bundle exec rails console
User.last.update_attribute(:admin, true)

You could also push the app again and add a command with the -c option:

cf push -f manifest.yml -c "User.last.update_attribute(:admin, true)"

It would mean some downtime but only a very limited amount of time.

If the app does not run anymore with a consequent push, run the same cf command with -c "null", Cloud Foundry is a bit buggy that way.

If it is only a once off command you want to pass this would be the recommended way, instead of putting it in the manifest file.

You can not pass commands to an already running CF application.

You can have the buildpack run commands for you at the start of the application by creating a manifest.yml file at the root of your application and specifying the command.

Sample manifest.yml:

---
applications:
- name: my-rails-app
  command: bundle exec rake cf:on_first_instance db:migrate && bundle exec rails s -p $PORT -e $RAILS_ENV
