如何避免解决Rails中的路线？

resources :services, :only => [:index, :show]

resources :services, :only => [:index, :show], :except => :new

resources :services, :except => :new, :only => [:index, :show]

MyApp::Application.routes.draw do
  resources :services, :only => [:index, :show]
  resources :packages,:only => [:index, :show]

  get \"pages/home\"
  get \"pages/about\"
  get \"pages/help\"

  root :to => \'packages#index\'

  namespace \"admin\" do
    get \"pages/home\"
    get \"pages/about\"
    get \"pages/help\"

    resources :services
    match \"/services/:id/add_to_package/:package_id\" => \"services#add_package\",       :as => :add_package_to_service,      :via => :post, :id => /\\d+/, :package_id => /\\d+/
    match \"/services/:id/remove_from_package/:package_id\" => \"services#remove_package\", :as => :remove_package_from_service, :via => :post, :id => /\\d+/, :package_id => /\\d+/

    resources :packages 
    match \"/packages/:id/add_service/:service_id\" => \"packages#add_service\",       :as => :add_service_to_package,      :via => :post, :id => /\\d+/, :service_id => /\\d+/
    match \"/packages/:id/remove_service/:service_id\" => \"packages#remove_service\", :as => :remove_service_from_package, :via => :post, :id => /\\d+/, :service_id => /\\d+/

    resources :users

    root :to => \'pages#home\'
  end
end
