Question

当使用名为format.mobile的格式/ mimetype时，我想执行一项操作，要求用户首先使用before_filter :authenticate_user使用登录，但它不会将我重定向到设计的登录页面。要做insted，它会在我的服务器日志中返回一条消息Completed 401 Unauthorized in 336ms并且不会将我重定向到登录页面。我正在使用jquerymobile为我的移动支持，如何进行重定向调用。

我遇到了同样的问题，因为我使用的是jquery mobile，它使用了对link_to方法的AJAX调用。就我而言，我通过在链接中添加以下内容使其成为常规link_to（非基于AJAX）

data-ajax="false"

在link_to选项中，即：

link_to 'Model', {:controller => "models", :action => "any_action"}, "data-ajax" => "false"

我希望有一天可以帮助某人。干杯! Yohann。
