Rails突然给我以下错误

我想要做的是当我点击免费页面上的视图，这是关联到公司名单，应该问我登录，但我仍然可以做到。现在它在登录后导致我另一个问题，当我点击公司列表的视图时，它向我显示以下错误。我不知道是哪个导致错误。任何人都可以告诉我什么是错误以及如何解决它。Rails突然给我以下错误

而我没有任何方法称为login_required，我有之前，但我评论它。

看起来，你在呼唤，现已灭绝，login_required从before_action回调方法在你的控制器之一。

要么你应该删除回调，或恢复你的方法。

意味着我怎么能这样做，我刚刚在我的控制器中评论了#before_filter：login_required，：only => [：user_rating]。 – user3144005

你究竟是什么意思？ – thomasfedb

我已将我的电话撤回，但是相同，如何恢复我的方法 – user3144005
