Ruby on rails Rails路由弃用警告

我有一个Rails 4.2.1应用程序，并在我的routes.rb中收到了一个弃用警告

DEPRECATION WARNING: Defining a route where `to` is a controller without an action is deprecated. Please change `to: :super_admin` to `controller: :super_admin`. (called from block in <top (required)>

---

我必须更改什么？

使用

controller:：super\u admin

而不是

to:：super\u admin

。这也在弃用警告消息中提到。

使用

controller:：super\u admin

而不是

to:：super\u admin

。弃用警告消息中也提到了这一点。

真正正确的是：

：controller=>：super\u admin

，但感谢您的提示！我很高兴能帮助你：）真正正确的是：

：controller=>：super_admin

但是谢谢你的提示！我很高兴能帮助你：）为什么这是被高估的？为什么这是被高估的？
