我有一堆activerecord類,看起來像我喜歡的類似!如何DRY多態activerecord類?
我可以擴展一個基類來幹這些方法嗎,還是會混淆rails?
也許我可以分享一些東西,但不是別人?
如果不是 - 最好的方法是什麼?
千恩萬謝;)
class Stage < ActiveRecord::Base
acts_as_taggable
has_many :services, :as => :serviceable
belongs_to :event
belongs_to :user
after_save :tag!
def t(s)
self.tag_list.add s
self.event.tag_list.add s
end
# injected to after_save -> http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html
def tag!
s = self
if s.id > 0 then s.t "id-greater-than-0" end
if s.id > 0 then s.t "some-stage-specific-stuff" end
self.tag_list
end
end
class Sound < ActiveRecord::Base
acts_as_taggable
has_many :services, :as => :serviceable
belongs_to :event
belongs_to :user
after_save :tag!
def t(s)
self.tag_list.add s
self.event.tag_list.add s
end
# injected to after_save -> http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html
def tag!
s = self
if s.id > 0 then s.t "some-sound-specific-stuff" end
self.tag_list
end
end
