Rails 活动模型序列化器 - JSON Api

Question

我正在使用 AMS 版本 0.10 并希望使用 json-api 规范来呈现我的响应。但是，我很难为我的关系数据呈现 'included' 键。我有以下设置：

products_controller.rb

class Api::V1::ProductsController < ApplicationController
...
respond_to :json

def show
  respond_with Product.find(params[:id])
end
...

product_serializer.rb

class ProductSerializer < ActiveModel::Serializer
  attributes :id, :title, :price, :published
  has_one :user  
end

user_serializer.rb

class UserSerializer < ActiveModel::Serializer
  attributes :id, :email, :auth_token, :created_at, :updated_at
end

products_controller_spec.rb

before(:each) do      
  @product = FactoryGirl.create :product
  get :show, params: { id: @product.id }
end  
...
it "has the user as a embeded object" do
  product_response = json_response
  puts "&&&&&&&&&&&&&&&"
  puts product_response #output below

  #expect(product_response[:user][:email]).to eql @product.user.email
end
...

json_response

{:data=>{:id=>"1", :type=>"products", :attributes=>{..working..}, :relationships=>{:user=>{:data=>{:id=>"1", :type=>"users"}}}}}

我想知道如何获取嵌套资源的 'included' 部分。

示例（来自 http://jsonapi.org/format/#introduction）

{
"data": [{
"type": "articles",
"id": "1",
"attributes": {
  "title": "JSON API paints my bikeshed!"
},
"links": {
  "self": "http://example.com/articles/1"
},
"relationships": {
  "author": {
    "links": {
      "self": "http://example.com/articles/1/relationships/author",
      "related": "http://example.com/articles/1/author"
    },
    "data": { "type": "people", "id": "9" }
  }
}],
"included": [{
  "type": "people",
  "id": "9",
  "attributes": {
    "first-name": "Dan",
    "last-name": "Gebhardt",
    "twitter": "dgeb"
  },
  "links": {
    "self": "http://example.com/people/9"
   }
},

我以前从未使用过 AMS，因此非常感谢您的帮助。

非常感谢

解决方案就在这里 https://github.com/rails-api/active_model_serializers/blob/master/docs/jsonapi/schema.md。

基本上我将以下内容添加到我的控制器操作中 (GET products/1)

render json: product, include: params[:include]

这将允许请求系统通过为要处理的 api 添加参数 include='user' 来确定他们是否想要包含嵌套模型。

谢谢
