使用ActiveModel :: Serializers来包含两个父json数组 [英] Use ActiveModel::Serializers to include two parent json arrays

问题描述

我正在尝试发送我的前端应用程序json，如下所示：

I'm trying to send my front-end application json that looks like this:

{
  facilities: [
     {id: 5, name: 'happy days ranch', location: { address: '1424 Pastoral Lane', zipcode: '25245'}, instructor_ids: [2, 4, 9]}
  ],
  instructors: [
     {id: 4, name: 'Johnny Pheonix', skill: '8', picture: 'aws_url', facility_ids: [5, 8, 12}
  ]
}

我尝试过的东西

Things I have tried

render :json => @facilities 

序列化程序发现了这一点。好极了！但是这不包括任何教练

The serializer discovers this. Yay! But this does not include any instructors

render :json => {facilities: @facilities, instructors: @instructors}

这给了我一个讲师数组和一个设施数组，但是没有使用activeModel :: Serializers。

This gives me an instructors array and a facilities array, but activeModel::Serializers is not used.

render :json => [@facilities, @instructors]

起初我很兴奋这个，因为它给了我两个数组，并使用ActiveModel :: Serializers。但是，这是JSON的样子：

At first I was excited about this one, because it gave me two arrays, and it used ActiveModel::Serializers. However, this is what the JSON looked like:

{facilities: [
  {facilities: [
    #my facilities data
  ]},
  {facilities: [
    #my instructor data
  ]}
]}

我正在尝试甚至允许ActiveModel :: Serializers？如果是这样，怎么样？

提前感谢！

Is what I'm trying to do even allowed by ActiveModel::Serializers? If so, how?

Thanks much in advance!

推荐答案

我通过创建一个名为Search的类来解决它，其中包含ActiveModel的各个方面

I solved it by creating a class called Search that incorporates aspects of ActiveModel

class Search
  include ActiveModel::Serialization
  include ActiveModel::SerializerSupport

  attr_accessor :facilities, :instructors

  def initialize(facilities, instructors)
    @facilities, @instructors = facilities, instructors
  end
end

然后我创建了一个搜索控制器（没有什么有趣的）和一个搜索序列化程序。

Then I created a Searches controller (nothing interesting there) and a Search serializer.

class SearchSerializer < ActiveModel::Serializer
  has_many :instructors, embed: :objects
  has_many :facilities, embed: :objects
end

这创建了我想要的json，虽然现在它被包装在搜索哈希中：

This creates my desired json, although now it is wrapped in a search hash:

{search: {
  #the stuff I wanted 
}}
