Rails:Elasticsearch:通过关联映射

Question

我正在尝试在建立has_many, :through关联时索引模型,但是没有显示任何结果.

class Business < ActiveRecord::Base
  include Tire::Model::Search
  include Tire::Model::Callbacks

  def self.search(params)
    tire.search(load: true) do
      query { string params[:q]} if params[:q].present?
    end
  end

  mapping do
    indexes :service_name
    indexes :service_description
    indexes :latitude
    indexes :longitude
    indexes :services do
      indexes :service
      indexes :description
    end
  end

  def to_indexed_json #returns json data that should index (the model that should be searched)
    to_json(methods: [:service_name, :service_description], include: { services: [:service, :description]})
  end

  def service_name
    services.map(&:service)
  end

  def service_description
    services.map(&:description)
  end

  has_many :professionals
  has_many :services, :through => :professionals

end

那么这就是服务模型

class Service < ActiveRecord::Base
  attr_accessible :service, :user_id, :description
  belongs_to :professional
  belongs_to :servicable, polymorphic: true
end

我还使用这个重新索引:

rake environment tire:import CLASS=Business FORCE=true

我可以在Business中搜索项目,但是当我尝试在Service中搜索某些内容时,我得到一个空的结果.

在与映射挣扎之后,我创建了一个宝石,使搜索更容易一些.https://github.com/ankane/searchkick

您可以使用该search_data方法来完成此任务:

class Business < ActiveRecord::Base
  searchkick

  def search_data
    {
      service_name: services.map(&:name),
      service_description: services.map(&:description)
    }
  end
end
