有条不紊地检查rabl

Question

我的问题模型与question_options有很多关系。

class Question < ActiveRecord::Base

  #relationship
  belongs_to :user

  has_many :question_options, :dependent => :destroy,:conditions => "is_deactivated is FALSE"

问题选项

class QuestionOption < ActiveRecord::Base
  attr_accessible :question_id,:option,:order,:is_other,:is_deactivated
  belongs_to :question

在我的问题_detail rabl我有

object @question
attributes :id, :status
child :question_options do
 attributes :question_id,:option,:order,:is_other
end

这里我只想回复is_other = false

的question_option

like the below....
    object @question
    attributes :id, :status
    child :question_options do
     attributes :question_id,:option,:order,:is_other = true
    end

如何检查rable中的情况？

Answer 1

一种简单的方法是使用if if option on attributes，例如：

object @question
attributes :id, :status
child :question_options do
 attributes :question_id,:option,:order,:is_other, 
    :if => lambda { |question_option| question_option.is_other }
end
