原标题:Rails Controllers => params[]

谁能帮助我了解nes脏的束缚?

我正在使用Apotomo。 但例如。 我们不能在申请管理员中承担这一责任。

我有一个简单的控制器显示行动。

if params[:id].present?
    @menu = Menu.find(params[:id])  
else
    @menu = Menu.first  
end

检查是否在《民法》中具体规定了男性补贴。 如果没有,它就显示第一个菜单。

只要我只读到URL。

但我 attributes了属性。 因此,我们一度访问URL /menus/17/categories/

它认为,第1类,而不是第2类。

一旦被 I,我可以叫:menu_id,并做罚款。 但是,不再在母物上工作。

How do I look for params[:id] of the menu object regardless of where I am in the URL?

我是否完全失踪了?

我也在这里开会:

resources :menus, :only => [:show, :home] do
  resources :categories, :only => [:index, :show]
end

感谢你的耐心。

问题回答

我将检查如何界定路线。 或许有理由将这一联系翻译成这种方式。
