Nope, that's it... simply adding a method to the controller class automatically creates a new action for that controller (at least with the default setup).
不,就是这样......简单地向控制器类添加一个方法会自动为该控制器创建一个新动作(至少使用默认设置)。
There's a little section about this in the Beginning Ruby on Rails book. Also, reading through the Ruby on Rails Getting Started Guide would probably be helpful. It demonstrates this.

Well, it actually depends on how your routing is set up. If it falls through to the default route:
嗯,这实际上取决于您的路由设置方式。如果它落到默认路由:
map.connect ':controller/:action/:id'
Then you have nothing else to do (see ActionController::Routing).
然后你没有别的事情要做(参见ActionController :: Routing)。
If you are using RESTful resources, you need to explicitly mention the action (and request type) in the routes.rb file (see ActionController::Resources).
如果您正在使用RESTful资源,则需要在routes.rb文件中明确提及操作(和请求类型)(请参阅ActionController :: Resources)。

As well as defining a new method in your controller, you will probably need to setup the view as well. By default the view corresponds to the controller and action name.
除了在控制器中定义新方法之外,您可能还需要设置视图。默认情况下,视图对应于控制器和操作名称。
So controller main with action index looks for a template in:
所以带有动作索引的控制器主要在以下位置查找模板:
views/main/index
