Rails，从网格中删除有效，但出现奇怪的异常

Question

我已经用 wice_grid gem 创建了一个网格，我正在尝试在每个条目上添加一个删除按钮。

我的html如下：

<%= grid(@business_grid) do |g|

  g.column name: 'ID' do  |business|
    business.id
  end

  g.column name: 'Title' do |business|
    business.title
  end

  g.column name: 'Description' do |business|
    business.description
  end

  g.column name: 'PlayStore URL' do |business|
    business.playstore_url
  end  

 g.column name: 'AppStore URL' do |business|
   business.appstore_url
 end

 g.column do |business|


   link_to "Delete", {:controller=>"businesses", :action=>"delete_business",:business=>business.id}


 end

end -%>

我的控制器中的任何一个：

class BusinessesController < ApplicationController


def create

    @business = Business.new(:title => params[:title], :description => params[:description], 
        :playstore_url => params[:playstore_url], :appstore_url => params[:appstore_url])
      if @business.save

        render json: { status: 'success' }  
      else
        render json: { status: 'error', errors: @business.errors.full_messages }
      end

end

def destroy

    @business = Business.find(params[:id])
    @business.destroy
        respond_to do |format|
          format.html {  render :partial => 'businessPartial'}
          format.xml  { head :ok }

        end

end



end

删除功能确实有效，它确实删除了该项目，但随后我收到一个 ActionController 异常，提示找不到该对象

我好像删了再找，但不明白为什么。这是我单击删除 link 时得到的屏幕截图。当我刷新的时候项目没有了，这意味着删除功能有效。

我尝试搜索，但没有找到任何具体信息。任何帮助表示赞赏。

编辑我的 development.log 文件仅按删除按钮后：

我在我的视图控制器（称为仪表板）中初始化了@business_gird

def dashboard
      @substore_grid = initialize_grid(Substore)
      @business_grid = initialize_grid(Business)
      @user_grid = initialize_grid(User)

  end

rake 路线截图：

我的猜测是您的 'businessPartial' 部分正在尝试使用已删除的 @business 变量

format.html {  render :partial => 'businessPartial'}

删除此行时出现错误吗？
