原标题:Filter a has_many association on a field value

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?

最佳回答

使用<代码>:conditions备选办法:

class Destination < ActiveRecord::Base
  has_many :events, :conditions => { :activated => true }
end
问题回答

一种可能性是default_cop, e.g default_cop where (start = 1 )
