Question

我在路线中这样嵌套资源。这些可以在我的其他Rails 5应用程序上完美运行，但不能在我的Rails 6应用程序上运行。我不知道为什么它只能识别嵌套信息的第一层。

  resources :blogs do
    member do
      put 'like', to: 'blogs#upvote'
      put 'dislike', to: 'blogs#downvote'
    end
    resources :comments
      member do
        put 'like', to: 'comments#upvote'
        put 'dislike', to: 'comments#downvote'
      end
      resources :notations
  end

这是耙路给我的：

 blogs_user GET      /users/:id/blogs(.:format)                                                               users#blogs
                             like_blog PUT      /blogs/:id/like(.:format)                                                                blogs#upvote
                          dislike_blog PUT      /blogs/:id/dislike(.:format)                                                             blogs#downvote
                         blog_comments GET      /blogs/:blog_id/comments(.:format)                                                       comments#index
                                       POST     /blogs/:blog_id/comments(.:format)                                                       comments#create
                      new_blog_comment GET      /blogs/:blog_id/comments/new(.:format)                                                   comments#new
                     edit_blog_comment GET      /blogs/:blog_id/comments/:id/edit(.:format)                                              comments#edit
                          blog_comment GET      /blogs/:blog_id/comments/:id(.:format)                                                   comments#show
                                       PATCH    /blogs/:blog_id/comments/:id(.:format)                                                   comments#update
                                       PUT      /blogs/:blog_id/comments/:id(.:format)                                                   comments#update
                                       DELETE   /blogs/:blog_id/comments/:id(.:format)                                                   comments#destroy
                                       PUT      /blogs/:id/like(.:format)                                                                comments#upvote
                                       PUT      /blogs/:id/dislike(.:format)                                                             comments#downvote
                             notations GET      /blogs/:id/notations(.:format)                                                           notations#index
                                       POST     /blogs/:id/notations(.:format)                                                           notations#create
                          new_notation GET      /blogs/:id/notations/new(.:format)                                                       notations#new
                         edit_notation GET      /blogs/:id/notations/:id/edit(.:format)                                                  notations#edit
                              notation GET      /blogs/:id/notations/:id(.:format)                                                       notations#show
                                       PATCH    /blogs/:id/notations/:id(.:format)                                                       notations#update
                                       PUT      /blogs/:id/notations/:id(.:format)                                                       notations#update
                                       DELETE   /blogs/:id/notations/:id(.:format)                                                       notations#destroy

例如，在我的另一个应用上，它将产生

/blogs/:blog_id/comments/:id/like

Answer 1

您缺少“ do”“ end”块语法

resources :blogs do
  member do
    put 'like', to: 'blogs#upvote'
    put 'dislike', to: 'blogs#downvote'
  end
  resources :comments do # here
    member do
      put 'like', to: 'comments#upvote'
      put 'dislike', to: 'comments#downvote'
    end
    resources :notations
  end # and here
end

无论如何，Rails指南不建议嵌套两个以上级别。

Answer 2

我复制了您的路线，并复制到两个应用程序（Rails 5和Rails 6）中，并且都产生了相同的路线（没有三个嵌套级别）。如果您想使用/blogs/:blog_id/comments/:id/like路线，则必须进行一些小的更改。

  resources :blogs do
    member do
      put 'like', to: 'blogs#upvote'
      put 'dislike', to: 'blogs#downvote'
    end
    resources :comments do
      member do
        put 'like', to: 'comments#upvote'
        put 'dislike', to: 'comments#downvote'
      end
    end
    resources :notations
  end

Rails嵌套的路线无法按预期运行
