Question

当我点击Destroy链接时，帖子被打开（呈现show动作）而不是被销毁。

视线中的一行：

<%= link_to 'Destroy', post_path(post),
                method: :delete, data: { confirm: 'Are you sure?' } %>

posts_controller.rb片段：

  def destroy
    @post = Post.find(params[:id])
    @post.destroy
    redirect_to posts_path
  end

耙路线：

                posts GET    /posts(.:format)                            posts#index
                      POST   /posts(.:format)                            posts#create
             new_post GET    /posts/new(.:format)                        posts#new
            edit_post GET    /posts/:id/edit(.:format)                   posts#edit
                 post GET    /posts/:id(.:format)                        posts#show
                      PATCH  /posts/:id(.:format)                        posts#update
                      PUT    /posts/:id(.:format)                        posts#update
                      DELETE /posts/:id(.:format)                        posts#destroy

在routes.rb

中

  resources :posts do
    resources :comments
  end

在我点击destroy链接时的development.log中：

Started GET "/posts/5" for 127.0.0.1 at 2013-12-28 21:51:40 +0000
Processing by PostsController#show as HTML

Completed 200 OK in 18ms (Views: 15.8ms | ActiveRecord: 0.8ms)

我知道问题可能是因为我在我的routes.rb中使用“resources：posts”但是如何删除帖子呢？

如果您需要任何其他信息，请告诉我们。感谢

Answer 1

不应该

<%= link_to 'Destroy', post, method: :delete, data: { confirm: 'Are you sure?' } %>

你在做什么：

<%= link_to 'Destroy', post_path(post),method: :delete, data: { confirm: 'Are you sure?' }%>

所以，当你点击你给它的链接post_path(post)时，这说明路线好了，转到post_path并传入我点击的那个帖子。虽然你应该做的就是给它一个对象post，然后rails会处理其余部分。

Answer 2

必须在/layout/application.html.erb

中添加

<%= javascript_include_tag 'application' %>
<%= csrf_meta_tag %>

销毁帖子问题，渲染显示动作但不破坏帖子
