Ruby on rails 3 提交表单databasedotcom gem时在嵌套控制器上路由错误

我正在使用databasedotcom&databasedotcomrailsgem，以便从表单提交中生成销售线索。在我将控制器嵌套在父控制器下之前，它一直是独立工作的，现在当我按submit时，出现以下错误：

No route matches [POST] "/events/516ee9a0421aa9c44e000001/leads/new"

以下是我的全部代码：

resources :events do
  resources :leads
end

class LeadsController < ApplicationController
   include Databasedotcom::Rails::Controller

  def new
    @lead = Lead.new
    respond_to do |format|
    format.html # new.html.erb
    format.json { render :json => @lead }
    end
 end

 def create
   @lead = Lead.new(params[:lead])
   @lead.event_id = params[:event_id]
   @lead['OwnerId'] = '005b0000000WxqE'   
   @lead['IsConverted'] = false
   @lead['IsUnreadByOwner'] = false
   respond_to do |format|
   if @event_lead.save
    format.html { redirect_to @lead, :notice => 'Lead was successfully created.' }
    format.json { render :json => @lead, :status => :created, :location => @lead }
  else
    format.html { render :action => "new" }
    format.json { render :json => @lead.errors, :status => :unprocessable_entity }
  end
  end
  end
end   

<%= simple_form_for [@event, @lead], url: new_event_lead_path do |f| %>
  <%= f.input :Download_Brochure__c, :check => "true",  :as => :boolean, :as => :hidden %>
  <%= f.input :FirstName %>
  <%= f.input :LastName %>

问题出在你的表格上。使用您编写的路由，

new\u事件\u lead\u路径

映射到您的

LeadsController#new

操作的GET请求。在命令行上运行

rake routes

，以确认这一点

您想将表单提交给

LeadsController\create

。当您在[@event，@Lead]的表达式

simple\u form_中使用
Lead
的新实例时，Rails将为您设置此选项，前提是您不重写url。因此，请更新您的表格：

<%= simple_form_for [@event, @lead] do |f| %>
