Capistrano deploy to staging and production

I am trying to deploy a Ruby On Rails app to both staging and then production using Capistrano. The only difference between the two is the :domain and the :repository I have followed this guide here: https://github.com/capistrano/capistrano/wiki/2.x-Multistage-Extension I have searched around the net and all I find are articles that basically rehash what I have above. I have tried just setting the :domain and :repository in the config/deploy/staging.rb and config/deploy/production.rb I have checked my spellings to make sure I spelt the sub-dirs correctly and the names of the files. Reading this article: staging and live app with capistrano it looks like I should just be able to declare the differences here. It doesn't look like the staging.rb file is actually being read. I changed my "deploy.rb" to have a single swear word as the first line, "cap deploy" gives me the expected error. If I put a single swear word on the first line of "staging.rb" or "production.rb" I get the same error: ``` `method_missing': undefined local variable or method `domain' ``` The line in question is: ``` role :web, domain ``` because the value is not being picked up. But surely it should fail on the single swear word in staging.rb or production.rb and not run at all? If I move the :domain and :repository back into the main "deploy.rb" file I get the error with the swear word. So it would seem that I can't set variables in the "staging.rg" and "production.rb" files but just complete tasks. Any help would be much appreciated or do you think I should just take the pizza delivery job ... deploy.rb: ``` require 'capistrano/ext/multistage' set :stages, %w(production staging) set :default_stage, "staging" set :user, 'dave' set :applicationdir, "~/rails/example.com" set :scm, 'git' set :git_enable_submodules, 1 # if you have vendored rails set :branch, 'master' set :git_shallow_clone, 1 set :scm_verbose, true set :keep_releases, 5 after "deploy:update", "deploy:cleanup" # roles (servers) role :web, domain role :app, domain role :db, domain, :primary => true after "deploy", "deploy:migrate" # deploy config set :deploy_to, applicationdir set :deploy_via, :export # set :rake, 'bundle exec rake' # additional settings default_run_options[:pty] = true # Forgo errors when deploying from windows set :ssh_options, {:forward_agent => true} #ssh_options[:keys] = %w(/home/user/.ssh/id_rsa) # If you are using ssh_keysset :chmod755, "app config db lib public vendor script script/* public/disp*"set :use_sudo, false # Passenger namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles => :app, :except => { :no_release => true } do run " touch #{File.join(current_path,'tmp','restart.txt')}" end end ``` And my config/deploy/staging.rb file: ``` set :domain, 'example.com' set :repository, "ssh://dave@example.com/~/rails/chamonix-mont-blanc.net" ``` If I put the :domain and :repository in the main "deploy.rb" it all works fine and dandy.
