Question

我现在正在使用一些嵌套资源 - 用户有很多制造商，制造商有很多行。我可以通过输入URL手动来访问行显示视图，因为它看起来像/ manufacturer / 37 / lines / 5。但是，当我查看制造商/ 37 /行页面时，我将鼠标悬停在单个行的“show”链接上，它会尝试在接近结尾的URL中填充一段时间，当我点击它时，它无处可去。比如/manufacturer/37/lines.5，它似乎不是有效的URL。有人可以帮助我吗？

的routes.rb

  resources :manufacturers do
    resources :lines
  end

  devise_for :users
  root "pages#home"

  get "about" => "pages#about"

  match 'users/:id' => 'users#show', :via => "get"
  match '/users', :to => 'users#index', :as => "all_users", :via => "get"
  match '/users/:name' => 'users#show', via: :get, as: :public_profile

rake routes

Answer 1

使用单数line，而不是复数lines：

manufacturer_line_path(line.manufacturer, line)

更新：

你的销毁链接看起来也很可疑 - 它应该与show动作的网址相同。
