如何将 OR 逻辑与 name_scope 结合起来？
无论如何，是否可以组合多个named_scope，但将它们用作OR逻辑？
named_scope :a, { :conditions => ["posts.type_post == #{PERSONAL}"] }
named_scope :b, { :conditions => ["posts.type_post == #{PUBLIC}"] }
有没有办法使用这些 a 和 b 以便我得到 posts.type_post == PERSONAL 或 posts.type_post == PUBLIC ？
谢谢

is there a way to use these a and b such that I get posts.type_post == PERSONAL or posts.type_post == PUBLIC ?
Thank you
