ruby-on-rails - Rails/Ember-active_model_serializer-侧面加载时未定义的方法 `object'

Question

我试图在Ember应用程序的active_model_serializer中加载数据，并在尝试包含对象时收到NoMethodError:

undefined method `object' for #Email:0x00000100d33d20

仅当设置:include => true时才会发生，如下所示:

class ContactSerializer < ActiveModel::Serializer
  embed :ids, :include => true
  attributes :first_name, :last_name
  has_many :emails
end

我的模型如下所示:

class Contact < ActiveRecord::Base
  attr_accessible :first_name, :last_name, :company,
  belongs_to :account
  belongs_to :user
  has_many :emails
end

class Email < ActiveRecord::Base
  attr_accessible :email_address, :email_type_id, :is_primary  
  belongs_to :contact
end

我的 Controller 如下所示:

def show
  @contact = @current_user.contacts.where(:id => params[:id]).includes(:emails).first
  render :json => @contact
end

提前致谢。

Answer 1

如上文Deefour所述，请确保您有一个用于任何侧载对象的序列化程序。在这种情况下，创建EmailSerializer:

class EmailSerializer < ActiveModel::Serializer
  attributes :id, :email_address
end
