Question

在我的Rails应用程序中，我使用的是太阳黑子，因此用户可以搜索“引脚”（如帖子）。一切正常，我将数据作为JSON返回。

但是，我还想在JSON响应中包含与每个“pin”相关联的“用户”数据。

我不需要将“用户”包含在搜索中，而只需要在搜索完成后将每个“引脚”作为数据。

我的搜索工作正常，但我无法弄清楚如何添加用户数据。

module Api

    module V1

        class PinsController < ApplicationController 

            respond_to :json

            def index

                _search = Sunspot.search(Pin) do

                    fulltext params[:q] do

                        highlight :title
                        phrase_fields :title => 2.0
                        phrase_slop 1
                        minimum_match 1

                    end

                    facet(:position_id, :type_id, :instrument_id, :genre_ids, :skill_id)

                    with(:position_id, params[:position]) if params[:position].present?
                    with(:type_id, params[:type]) if params[:type].present?
                    with(:instrument_id, params[:instrument]) if params[:instrument].present?
                    with(:genre_ids).all_of(params[:genre]) if params[:genre].present?
                    with(:skill_id, params[:skill]) if params[:skill].present?

                    paginate(:page => params[:page], :per_page => 25)

                end

                _pins = _search.results

                _pins_positions = []

                _search.facet(:position_id).rows.each do |row|
                    _facet = Position.find_by_id(row.value)
                    _object = _facet.attributes
                    _object["count"] = row.count
                    _pins_positions << _object

                _search.facet(:type_id).rows.each do |row|

                    _object = _facet.attributes
                    _object["count"] = row.count
                    _pins_instruments << _object

                _search.facet(:genre_ids).rows.each do |row|

                _pins_positions = _pins_positions.sort_by { |e| e["title"] }
                _pins_types = _pins_types.sort_by { |e| e["title"] }
                _pins_instruments = _pins_instruments.sort_by { |e| e["title"] }
                _pins_genres = _pins_genres.sort_by { |e| e["title"] }
                _pins_skills = _pins_skills.sort_by { |e| e["title"] }

                _response = {

                respond_with _response

典型的回答如下：

{"pins":[{
"id":95,
"user_id":22,
"title":"Ratione sint odio vitae in quis aspernatur.",
"description":"Sunt ut pariatur aut ipsum sit unde alias.",
"latitude":null,
"longitude":null,
"position_id":1,
"type_id":1,
"instrument_id":4,
"skill_id":1,
"soundcloud_url":null,
"created_at":"2012-09-04T06:54:17.000Z",
"updated_at":"2013-10-14T21:58:17.000Z",
"deleted_at":null
}],
"facets":{
"positions":[{
"id":1,
"title":"Non-Professional",
"token":"non-professional","count":2
}],
"types":[{
"id":1,
"title":"Wanted",
"token":"wanted",
"count":2
}],
"instruments":[{
"id":4,
"title":"Synth",
"token":"synth",
"count":2
}],
"genres":[{
"id":12,
"title":"Folk",
"token":"folk",
"count":2
},
{
"id":16,"title":"Hip Hop","token":"hiphop","count":2}
],
"skills":[{
"id":3,
"title":"Advanced",
"token":"advanced",
"count":1},
{
"id":1,
"title":"Novice",
"token":"novice",
"count":1
}]
}}

但是，理想情况下，我想在JSON中为每个“pin”包含相关的“用户”数据。正如你所看到的，我在这里所有的都是“user_id”...但是我希望这个JSON API相当“平坦”并包含另一个名为“user”的哈希键，其中包含“first_name”，“age”等字样， “性别”等。

如果我正在使用传统的View模板，我可以将“pin”作为实例变量公开，并执行以下操作：@pin.user.profile.first_name - 在Sunspot中构建数据时如何执行此操作？

希望我已经说清楚了。非常感谢！

我通过创建一个空数组，从Sunspot循环结果，找到相应的用户并推送到数组来找到解决方案。

_results = _search.results
_pins = []

_results.each do |pin|
    _object = pin.attributes
    _object["user"] = { :profile => pin.user.profile }
    _pins << _object
end

我现在得到一个结构，其中配置文件数据嵌套在引脚哈希中的用户密钥中，如下所示：
