我有两个模式:
class Event < ActiveRecord::Base
belongs_to :destination
end
class Destination < ActiveRecord::Base
has_many :events
end
我的“发明”模式有一个“活跃的”领域,而我只想在称为目的地时展示已经启动的事件。 活动。 如何总是在活性领域进行过滤?

使用<代码>:conditions备选办法:
class Destination < ActiveRecord::Base
has_many :events, :conditions => { :activated => true }
end
一种可能性是default_cop
, e.g default_cop where (start = 1 )
