Rails Routes 弃用警告

Question

我有一个 Rails 4.2.1 应用程序并在我的 routes.rb 中收到弃用警告

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)>

路线看起来像这样：

 get "/super_admin(/:action(/:id))", :to => "super_admin", :constraints => {:subdomain => "admin"}
 get "/", :to => redirect("/super_admin"), :constraints => {:subdomain => "admin"}
 get "/super_admin(/:action(/:id))", :to => "super_admin", :constraints => {:subdomain => "admin.staging"}
 get "/", :to => redirect("/super_admin"), :constraints => {:subdomain => "admin.staging"}
 get "/super_admin(/:action(/:id))", :to => redirect("/")

我需要改变什么？

使用controller: :super_admin 代替to: :super_admin。弃用警告消息中也提到了这一点。
