Rails4 link_to Destroy入门教程

Question

我正在学习入门教程（创建博客），而link_to Destroy功能不正常。在终端中，它总是将其解释为#show。

在阅读类似的问题时，我了解到删除必须转换为一个帖子，以便浏览器对其进行解释。这似乎不会发生。

Started GET "/posts/4" for 127.0.0.1 at 2013-08-09 13:45:20 -0600
Processing by PostsController#show as HTML
  Parameters: {"id"=>"4"}
  Post Load (0.6ms)  SELECT "posts".* FROM "posts" WHERE "posts"."id" = ? LIMIT 1  [["id", "4"]]
  Rendered posts/show.html.erb within layouts/application (0.4ms)
Completed 200 OK in 13ms (Views: 8.6ms | ActiveRecord: 0.6ms)

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

    redirect_to action: :index
end

<% @posts.each do |post| %>
  <tr>
    <td><%= post.title %></td>
     <td><%= post.text %></td>
    <td><%= link_to 'Show', post %></td>
    <td><%= link_to 'Edit', edit_post_path(post) %></td>
    <td><%= link_to 'Destroy',  { action: :destroy, id: post.id }, method: :delete, data: { confirm: 'Are you sure?' } %></td>
  </tr>
 <% end %>

Blog::Application.routes.draw do
   resources :posts do
     resources :comments
   end
  root to: 'welcome#index'
end

Answer 1

试试这个

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