所以我最近在我的应用程序中安装了rack-pjax来制作它，所以有些侧边栏不会在导航时重新加载，我让它在开发中工作，但是当我把它推到heroku时，出于某种原因，它不起作用。
如果我导航到“/ music”，它会重新加载整个页面，URL从“/ music”变为“/ music＃”并返回“/ music”。
在heroku日志中，您可以看到它发送两次GET请求，这解释了URL中的差异。如果第二个GET请求没有发生，它应该可以工作。
这是我在开发过程中记录的日志：

答案 0 :(得分：1)
在致电pjax之前，请尝试将其添加到您的JavaScript：
$(document).on('pjax:timeout', function() {
return false;
});
这将禁用超时。我有这个完全相同的问题，问题是我的应用程序太慢了，加载时间太长，而pjax会取消请求并发送浏览器。你当然可以增加超时但我认为这更好。
