我有像这样的序列化器

class UserSeriazer < ActiveModel::Serializer
  attributes :name, :email
end

生成的 json 如下

{
  name: 'james'
  email: 'j@sample.com'
}

我如何在自定义键下包装上面的json 项目customer

{
  customer:
    {
      name: 'james'
      email: 'j@sample.com'
    }

}

我尝试了诸如属性：名称，：电子邮件，密钥：：客户之类的东西，但没有用。提前致谢。

我在Ubuntu 12.10 64bit上使用Ruby 2.1.我无法安装Nokogiri因为它需要libXSLT和libxml.我试图安装这两个,但得到了这个错误:
