ruby-on-rails - 更新 rails 2 路由到 rails 3

Question

嗨，我被一些铁轨路由困住了，

这在 rails 3 路由中应该如何看？：

map.resources :books do |book|  
    book.resources :comments, :only => :create  
end  

Answer 1

resources :books do
  resources :comments, :only => :create
end

会做的。Ruby on Rails 指南中有关 Rails 3 路由的更多信息：Rails Routing from the Outside In
