How can I get Rails 3.2 to restart the installed rack application on request in development mode?

 # Reload Grape in development mode api_reloader = ActiveSupport::FileUpdateChecker.new(Dir["path/to/you/api/dir/**/*"], true) do Rails.application.reload_routes! # or do something better here end ActionDispatch::Callbacks.to_prepare do api_reloader.execute_if_updated end
