Rails before_filter和动作识别 [英] Rails before_filter and action identification

问题描述

我想在我的控制器中编写一个before_filter来标识下一步将要执行的动作。

I want to write a before_filter in my controller to identify the action which will execute next. This is for authorization purposes (this is somewhat like role_requirement plugin do..)

Ex：如果用户键入此url，则用于授权目的（这有点类似于role_requirement插件。） ：3000 / users ，默认情况下转到用户/索引操作。在我的用户控制器中，我有一个前置过滤器方法，例如 check_permission，我希望该方法将 index作为操作。

Ex: if a user types this url http://localhost:3000/users, default it goes to users/index action. And in my users controller i'm having a before filter method say 'check_permission' and i want that method to get 'index' as the action.

推荐答案

控制器上的 action_name 方法应该为您提供所需的内容。不过，它没有记录，因此无法保证它有一天不会消失。

The action_name method on the controller should give you what you're looking for. It's not documented, though, so there is no guarantee it won't disappear someday.

before_filter { |controller| logger.debug "Running before the #{controller.action_name} action" }
