Launching a Rails Console with Capistrano

If you're using the popular Capistrano web deployment framework, you will likely have wished you had an easy way to perform a quick task in the production rails console on one of your servers. Many thanks to @colszowka for this solution:

NOTE: This is for Capistrano v2. Things are different for v3.

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=nil)
  server ||= find_servers_for_task(current_task).first
  exec %Q(ssh #{server.host} -t 'cd #{current_path} && #{command}')
end

And, vòila! Run cap rails:console and you're in business.
