ActionController :: UrlGenerationError No嵌套资源的路由匹配

我有一个表格，其中每个用户都有一个对应的复选框。点击一个按钮即可删除所选的下列内容。ActionController :: UrlGenerationError No嵌套资源的路由匹配

下面是用户下的嵌套资源，我在我的控制器中有一个销毁方法，当我做耙路由时，我可以看到相应的路由＃destroy操作，但是当下列列表页面被加载时，它不会引发路由匹配错误。

routes.rb中：

resources :users do 
    resources :followings 
    resources :events 
    end

following_controller.rb：

class FollowingsController < ApplicationController 

    def index 
    @followings = Following.findFollowings(params.has_key?("user_id") ? params[:user_id] : current_user.id) 
    @following = Following.new 
    end 

    def destroy 
    Following.any_in(:following_id => params[:id]).destroy_all 
    render index 
    end 

    end

index.html.haml：

= form_for(@following, url: {action: 'destroy'}, :html => {:method => :delete, :role => 'form'}) do |f| 
     - @followings.each do |following| 
     = f.check_box "following_id" 
     = f.submit "Delete"

耙路线：

user_followings GET /users/:user_id/followings(.:format)   followings#index 
        POST /users/:user_id/followings(.:format)   followings#create 
    new_user_following GET /users/:user_id/followings/new(.:format)  followings#new 
edit_user_following GET /users/:user_id/followings/:id/edit(.:format) followings#edit 
     user_following GET /users/:user_id/followings/:id(.:format)  followings#show 
        PATCH /users/:user_id/followings/:id(.:format)  followings#update 
        PUT /users/:user_id/followings/:id(.:format)  followings#update 
        DELETE /users/:user_id/followings/:id(.:format)  followings#destroy

错误堆栈：

没有路由匹配{:action=>"destroy", :controller=>"followings", :user_id=>"540f5c6b7072610a4c040000"} 提取的源（左右线＃9）：

6 %ul 
7  = render partial: "shared/npo_menu", locals: {item: 'followings'} 
8 %section.following.notifications 
9  = form_for(@following, url: {action: 'destroy'}, :html => {:method => :delete, :role => 'form'}) do |f| 
10  .container 
11   .row.manipulate 
12    .pull-left

谢谢！

看起来像你的压痕可能会关闭，如果代码与您粘贴的代码相同。应该是一个缩进，然后following.check_box？ – Kevin 2014-09-24 20:05:06

表单布局看起来有点不寻常。你能解释为什么你在这个视图中使用两个不同的实例变量“@follow”和“@followings”？另外，为什么你在一个索引视图中渲染一个表单（并不是说它是错误的，但通常不是索引的用途）。 – Kevin 2014-09-24 20:24:32

@Kevin缩进在实际代码中是正确的，只是在这里粘贴了几行而不是整个哈姆。 “@followings”是要在索引页面上显示的列表。 “@following”是用户选择删除时的列表项目。 – Yeshasvi 2014-09-25 12:28:19

路由问题已解决。对于多次删除，路由必须声明为集合。这里有其工作的变化 -

的routes.rb

resources :users do 
     resources :followings do 
     collection do 
     delete 'destroy_multiple' 
     end  
     end 
     resources :events 
    end

followings_controller.rb

def destroy_multiple 
     Following.any_in(:following_id => params[:id]).destroy_all 

     respond_to do |format| 
     format.html { redirect_to user_followings_path } 
     format.json { head :no_content } 
    end

index.haml.html

= form_tag destroy_multiple_user_followings_path, method: :delete do
