ruby-on-rails - acts_as_follower 无法与我的 Rails3.2 应用程序正常工作

Question

由于我启用了远程 true，它应该立即将切换按钮“关注”更改为“取消关注”。
但事实并非如此。如果我重新加载页面，切换按钮会显示更改后的标签。
所以这意味着它实际上改变了后台的follow列的值。
我已经为此花了 3 天，但我仍然不知道:(
谁能帮我解决这个问题吗？代码有什么问题吗？或者我缺少一些 JQuery 文件？我是 Rails 新手...

您忘记将渲染放入跟随 Controller 中。

这里是我的测试代码，我使用了一些您的代码，但我使用 RubyCas-Server 作为身份验证层。

所以只需检查 Controller 、 View :)
