Question

在我的应用程序的某个部分中，销毁操作对我有用，但我无法在使用单独控制器的其他视图中使用它。

我收到错误：No route matches {:action=>"destroy", :controller=>"letsgo"}

查看：

<% for letsgo in @letsgos %>
<li>
<b>Let's Go...<span class="content"><%= letsgo.content %></span></b> 
<%= link_to 'Delete', { :controller => 'letsgo', :action => 'destroy'}, 
                      { :confirm => 'Are you sure?', :method => :delete, :remote => true} %>
<% end %>

路线：

  resources :letsgos, only: [:create, :destroy]

LetsGos控制器：

  def destroy
    @letsgo.destroy
    redirect_to root_url
  end

如果我在letsgos视图下<%= link_to "delete", letsgo, method: :delete, data: { confirm: "You sure?" }%>

，则此代码有效如果我在letsgos视图下工作，

销毁行动有效，但我在不同的文件夹下工作它不再有效。我正在做的是列出content表中的所有letsgos，并为每个内容提供销毁操作。

路线：

                letsgos_eatdrink GET      /letsgos/eatdrink(.:format)                   letsgos#eatdrink
             letsgos_listenwatch GET      /letsgos/listenwatch(.:format)                letsgos#listenwatch

                                 GET      /letsgos(.:format)                            letsgos#index
                                 POST     /letsgos(.:format)                            letsgos#create
                      new_letsgo GET      /letsgos/new(.:format)                        letsgos#new
                     edit_letsgo GET      /letsgos/:id/edit(.:format)                   letsgos#edit
                                 GET      /letsgos/:id(.:format)                        letsgos#show
                                 PATCH    /letsgos/:id(.:format)                        letsgos#update
                                 PUT      /letsgos/:id(.:format)                        letsgos#update
                                 DELETE   /letsgos/:id(.:format)                        letsgos#destroy

Answer 1

您没有将letsgo的ID传递给路线：

<%= link_to 'Delete', { :controller => 'letsgos', :action => 'destroy', :id => letsgo.id }, 
                      { :confirm => 'Are you sure?', :method => :delete, :remote => true} %>

正如你的路径所写：

letsgo DELETE   /letsgos/:id(.:format)                        letsgos#destroy

它没有经过测试，但应该像这样

Answer 2

这也适合我！只需在P之前添加DATA: ...并确认删除对话框即可。

{ :confirm..... }

没有路由匹配销毁行动
