The ActiveAclPlus system consists of access objects, which can be organized by access groups, that request privileges on each other. Allowing or denying access to a privilege is controlled by ACL (access control list entry) objects. Access objects and access groups can be instances of arbitrary ActiveRecord model classes enhanced by acts_as_access_object and acts_as_access_group. They are associated to ACL entries via polymorphic associations.

ActiveAclPlus系统由访问对象组成，访问对象可以由访问组进行组织，这些访问组可以相互请求权限。允许或拒绝对权限的访问由ACL（访问控制列表条目）对象控制。访问对象和访问组可以是acts_as_access_object和acts_as_access_group增强的任意ActiveRecord模型类的实例。它们通过多态关联与ACL条目相关联。

I personally like the Declarative Authorization Gem a lot - but that does not do tree traversal, but it allows at least inheritance from other rules

我个人非常喜欢声明性授权宝石 - 但这不会进行树遍历，但它至少允许从其他规则继承
