Question

按下follow / unfollow切换按钮后，我收到_follow.html.erb的ActionView :: MissingTemplate异常。我似乎无法通过follow / unfollow按钮超越这一点。我尝试了6种不同的方法，似乎都没有为我呈现正确的结果。如何设置follow / unfollow切换按钮在我的索引/显示视图中正常工作？

更新

当我点击关注按钮时，状态不会改变，用户也不会真正关注目标用户。我的服务器日志显示如下。

要让C:\Users\Username\AppData\Local\lxss\rootfs自动找到不显眼的JS部分，它也应该放在UsersController#follow文件夹中（即users）。

您的代码看起来很好，但由于您的部分代码位于app/views/users/follow.js.erb，因此您可能不小心将JS部分放在users/shared/_follow.html.erb中。
