Javascript 根据当前路线更改js.erb？

我在Rails应用程序中使用AJAX，这样当有人创建友谊时，按钮就会更新。问题是有两个地方可以建立友谊，每个地方的设计都略有不同，一个地方的按钮更小

我已经创建了两个助手来显示按钮

用户助手

我刚刚想出了解决这个问题的办法。在helpers中，我更改了用于触发JS的按钮的类。然后，在create.js.erb文件中，我有两个块，每个按钮一个。现在页面上的按钮将被更新，而另一个按钮将被忽略

新建Create.js.erb

你能不能在create.js.erb中使用insert-one javascript语句插入另一个javascript语句？这很有意义，但不确定当两个助手使用同一个控制器时如何传递额外的内容。因此，你没有说过如何知道在哪里显示一组操作按钮，而不是另一组。控制器是否知道这一点？即，它呈现一个带有此类按钮的页面，而呈现另一个带有不同按钮集的页面？如果是的话，你能使用条件逻辑吗？或者这两组按钮在同一页上？
