How to enter rails console on production via capistrano?

Question

I want to enter the rails console on production server from my local machine via capistrano. I found some gists, e.g. https://gist.github.com/813291 and when I enter console via

cap production console 

I get the following result

192-168-0-100:foldername username $ cap console RAILS_ENV=production
  * executing `console'
  * executing "cd /var/www/myapp/current && rails console production"
    servers: ["www.example.de"]
    [www.example.de] executing command
    [www.example.de] rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '1.9.3' -c 'cd /var/www/myapp/current && rails console production'
/var/www/myapp/releases/20120305102218/app/controllers/users_controller.rb:3: warning: already initialized constant VERIFY_PEER
Loading production environment (Rails 3.2.1)
Switch to inspect mode.

and thats it... Now I can enter some text, but nothing happens...

Has anybody an idea how to get that work or another solution for my problem?

Answer 1

I've added my own tasks for this kind of thing:

namespace :rails do
  desc "Remote console"
  task :console, :roles => :app do
    run_interactively "bundle exec rails console #{rails_env}"
  end

  desc "Remote dbconsole"
  task :dbconsole, :roles => :app do
    run_interactively "bundle exec rails dbconsole #{rails_env}"
  end
end

def run_interactively(command)
  server ||= find_servers_for_task(current_task).first
  exec %Q(ssh #{user}@#{myproductionhost} -t '#{command}')
end

I now say cap rails:console and get a console.
