Ruby on Rails让做网站像搭积木一样简单，例如使用acts_as_commentable的方法如下：

* Make you ActiveRecord model act as commentable.
class Model < ActiveRecord::Base
    acts_as_commentable
end
* Add a comment to a model instance
model = Model.new
comment = Comment.new
comment.comment = ‘Some comment’
model.comments << comment
* Each comment reference commentable object
model = Model.find(1)
model.comments.get(0).commtable == model
