Rails 3 通过复选框销毁多条记录 [英] Rails 3 destroy multiple record through check boxes

问题描述

我在使用复选框进行多次删除时遇到问题.当我删除多条记录时，它会获取复选框的 id，但它正在传递一个方法名称作为参数并显示错误.

I have issue with multiple delete using checkboxes. when i m deleting multiple records it get s ids for checkboxes but it is passing a method name as parameter and shows me error.

这是我的代码，

  **In my Controller method :**
  def destroy
    @ticket = current_user.tickets.find(params[:ticket_ids])
    @ticket.destroy

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


 def destroy_multiple
    Ticket.destroy(params[:tickets])

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

**In my index.html.erb**

<%= form_tag destroy_multiple_tickets_path, method: :delete do %>   
.
.
<td class="table-icon">
  <%= check_box_tag "ticket_ids[]", ticket.id %>
</td>
.
.
<%= submit_tag "Delete selected" %>

**In routes.rb**

resources :tickets do
  collection do
    delete 'destroy_multiple'
  end
end

它向我展示了这个错误::::

it shows me this error ::::

 Couldn't find Ticket with id=destroy_multiple [WHERE "tickets"."user_id" = 1]

通过争论::::

  {"utf8"=>"✓",
  "_method"=>"delete",
  "authenticity_token"=>"yHeRR49ApB/xGq1jzMTdzvix/TJt6Ysz88nuBEotHec=",
  "ticket_ids"=>["11",
  "12"],
  "commit"=>"Delete selected",
  "id"=>"destroy_multiple"}

推荐答案

do

Ticket.destroy(array_of_ids)
