Question

当我将浏览器指向http://localhost:3000/searches时，我收到以下错误：

Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

为什么呢？我该如何解决这个问题？

你有一个循环重定向; redirect_to searches_path只是将请求发回到同一个操作中。

尝试取出redirect_to行。这样Rails默认会呈现app/views/searches/index.html.haml。然后发布到表单应再次请求index并生成您想要的内容。

为什么我会用pg_search获得无限循环？
