Question

我还在制作我的食谱应用程序，我到了建立购物清单功能的地方，你可以点击链接“添加到杂货店列表”，它将添加给定的所有成分在新页面上购买食品清单的配方，您可以在杂货店的同时在智能手机上提取页面并随时标记项目。

虽然获得正确的路线但我遇到了一些困难。

所以我的杂货店名单出现在杂货店#show页面上，这就是我想要的地方。我想要将链接添加到配方页面，以便访问者可以简单地点击链接，然后他们将移动到购物清单。

现在，为了进入食谱＃2的购物清单页面，您必须使用以下网址：

localhost:3000/recipes/2/groceries/1

目前您可以看到我们必须使用以下路线：

recipe_grocery GET    /recipes/:recipe_id/groceries/:id(.:format) groceries#show

继承我想要的东西：

localhost:3000/recipes/2/groceries

我确信这很容易做到，但此刻它逃脱了我。所以你能提供任何帮助，我将永远感激不尽！

以下是我的佣金路线的下半部分：

     recipe_favorites POST   /recipes/:recipe_id/favorites(.:format)     favorites#create
     recipe_favorite DELETE /recipes/:recipe_id/favorites/:id(.:format) favorites#destroy
    recipe_groceries POST   /recipes/:recipe_id/groceries(.:format)     groceries#create
      recipe_grocery GET    /recipes/:recipe_id/groceries/:id(.:format) groceries#show
             recipes GET    /recipes(.:format)                          recipes#index
                     POST   /recipes(.:format)                          recipes#create
          new_recipe GET    /recipes/new(.:format)                      recipes#new
         edit_recipe GET    /recipes/:id/edit(.:format)                 recipes#edit
              recipe GET    /recipes/:id(.:format)                      recipes#show
                     PATCH  /recipes/:id(.:format)                      recipes#update
                     PUT    /recipes/:id(.:format)                      recipes#update
                     DELETE /recipes/:id(.:format)                      recipes#destroy
              drinks GET    /drinks(.:format)                           recipes#index {:category=>"drinks"}
             entrees GET    /entrees(.:format)                          recipes#index {:category=>"entrees"}
               sides GET    /sides(.:format)                            recipes#index {:category=>"sides"}
            desserts GET    /desserts(.:format)                         recipes#index {:category=>"desserts"}
          appetizers GET    /appetizers(.:format)                       recipes#index {:category=>"appetizers"}
               about GET    /about(.:format)                            welcome#about
                    root GET    /                                       welcome#index

这是我的路线档案：

Rails.application.routes.draw do

  devise_for :users
  resources :users, only: :show
  get 'comments/index'

  get 'comments/create'

  get 'comments/show'

  get 'comments/edit'

  get 'comments/new'

  resources :recipes do
    resources :comments, only: [:create, :show, :index, :new, :destroy]
    resources :favorites, only: [:create, :destroy]
    resources :groceries, only: [:create, :destory, :show]
  end

  get 'drinks' => 'recipes#index', :category => "drinks"
  get 'entrees' => 'recipes#index', :category => "entrees"
  get 'sides' => 'recipes#index', :category => "sides"
  get 'desserts' => 'recipes#index', :category => "desserts"
  get 'appetizers' => 'recipes#index', :category => "appetizers"


  get 'about' => 'welcome#about'

  root to: 'welcome#index'

end

Answer 1

要获得这样的路线：

localhost:3000/recipes/2/groceries

您可以使用以下方式更新routes.rb文件：

resources :recipes do
  # other routes
  resources :groceries, only: [:create, :destory, :show, :index] # adding :index to the list
end

这将为您提供一条新路线：

recipe_groceries GET    /recipes/:recipe_id/groceries(.:format)     groceries#index

然后，您将拥有上述路线，该路线将列出特定groceries的所有recipe，在您的上述情况下，recipe与id 2。
