Rails 3通过复选框破坏多条记录

问题描述：

我有多个使用复选框删除的问题。当我删除多个记录时，它获得了复选框的ID，但它传递一个方法名称作为参数，并显示我错误。Rails 3通过复选框破坏多条记录

这里是我的代码，

**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

它表明我这个错误::::

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

通行证arguement ::::

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

答

做

Ticket.destroy(array_of_ids)

答

嗨，更新您的控制器代码同样..

def destroy_multiple 
@tickets = Ticket.find(params[:ticket_ids]) 
@tickets.each do |ticket| 
ticket.destroy 
end 
end

其中u使用 “@ticketsts” 这个???这是更正和完善的代码....“Ticket.destroy（params [：ticket_ids]）” – SSR 2013-06-21 05:58:56

它的错字，我已经纠正它@SSR – Radhakrishna 2013-09-25 11:03:43

尝试此

Ticket.where(:id => params[:ticket_ids]).destroy_all

答

步骤：1 在routes.rb中

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

步骤：2在_form.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" %> 
<%end%>

STPE：3在控制器

def destroy_multiple 
    Ticket.destroy(params[:tickets]) 
    respond_to do |format| 
     format.html { redirect_to tickets_path } 
     format.json { head :no_content } 
    end 
end
