ember.js - 多级 hasMany 侧载

Question

我用来ActiveModel::Serializers将 JSON 输出到 Ember.js 应用程序。我使用侧载来最大化性能。

我可以告诉ActiveModel::Serializers侧载所有PhoneNumbers的SwitchboardSerializer吗？

switchboard_serializer.rb

class SwitchboardSerializer < ActiveModel::Serializer
  embed :ids, :include => true

  attributes :id, :name
  has_many :switchboard_entries
  has_many :sip_accounts, :through => :switchboard_entries
end

sip_account_serializer.rb

class SipAccountSerializer < ActiveModel::Serializer
  embed :ids, :include => true

  attributes :id, :auth_name, :caller_name, :sip_accountable_id
  has_many :phone_numbers
end

Answer 1

通过添加has_many :phone_numbers, :through => :sip_accounts到app/models/switchboard.rb我能够使用has_many :phone_numbersin switchboard_serializer.rb。:-)
