Rails 3.1 + Heroku：有人可以帮我破解这个Heroku日志吗？

我遇到了这个间歇性问题，我的客户端正在接收来自（我认为）对Heroku上的Rails服务器的单个HTTP请求的多个JSON响应。这是显示问题的Heroku日志......

我是Rails和Heroku的新手，因此我无法理解这个日志，足以弄清楚发生了什么。我的Rails应用程序是否在Heroku上接收来自客户端的多个HTTP请求，或者它只接收一个HTTP请求并返回多个JSON响应？

非常感谢您的智慧！

我偶尔会遇到这样的问题 - Javascript请求冒泡DOM并多次触发，而我只想触发一次。这可能会很快崩溃服务器，所以你一定要查看你的应用程序并确保你没有快速触发AJAX调用。

一个非常简单的方法就是在任何ajax调用之前或之后立即放置alert()，并查看它触发的次数与预期的次数。

我不知道这是不是你的问题，但我之前遇到过这种事情。
