Ruby on rails Ruby应用程序一直在响应，直到堆栈太深

我在这里不知所措。我有一个相当简单的事情要做，但似乎遇到了很多问题。我有直接的网络爬虫在工作中。人们发布请求并将其发送到队列中。如果他们想查询队列中的内容：路由是

127.0.0.1:8080/requests/id/1.json

响应是动作（def） CrawlerController是控制器。 请求就是模型

这是路线：（尽管我认为它不相关）

这是控制器内的def：

  def response
    @request = Request.find(params[:id])
   respond_to do |format|
     #format.html { render :action => "new"}
     format.json { render :json => @request.to_json }
    end
  end

我得到的错误是堆栈级别太深。如果我查看控制台输出：

编辑：第21行和第19行是@respond to do和format.json

很奇怪吧？

尝试将变量从

@request

重命名为其他变量。我认为，

@request

可能被Rails用于其他用途

---

还可以尝试将您的操作从

响应

重命名为其他操作。我认为，

response

可能被Rails用于其他用途。

我发誓，如果这是另一个缺失的端点块Shakes fistI，我发誓如果这是另一个缺失的端点块Shakes fistit，现在就改为未初始化常量。我要试着解决这个问题。就是这样。我想它现在变成了未初始化的常量。我要试着解决这个问题。就是这样。我想
