Как добавить фасет в Tire (asticsearch) в ассоциацию has_many

Question

Я хочу добавить фасет к ассоциации has_many.

Я перехожу с полнотекстового поиска в PostgreSQL на asticsearch.

В настоящее время у меня есть следующий запрос SQL для поиска (PostgreSQL):

rt = "#{Rule.table_name}"
Sentence.
  joins(:rules).joins(:regulations).joins(:speakers).
  where(:authority_name => params[:authority_name], :authority_detail_1 => params[:authority_detail_1]).
  where(:regulations => {:regulation_name => params[:regulation_name]}).
  where("#{rt}.description @@ #{Sentence.sanitize(words)} OR #{rt}.headline @@ #{Sentence.sanitize(words)}")

Я посмотрел на SO ответ о похожей проблеме (ассоциация HABTM)

Проблемы с Elasticsearch на запрос

и реализовал код с похожим подходом

Предложение AR класса

class Sentence < ActiveRecord::Base
  # other staff

  include Tire::Model::Search
  include Tire::Model::Callbacks

  mapping do
    indexes :id
    indexes :authority_name, :type => :string, :index => "not_analyzed"
    indexes :authority_detail_1, :type => :string, :index => "not_analyzed"
    indexes :authority_detail_2, :type => :string, :index => "not_analyzed"
    indexes :regulations, :type => :object, :properties => {
      :regulation_name => { :type => :string, :index => "not_analyzed" }
    }
  end

  def to_indexed_json
    to_json(:include => [:rules, :regulations, :speaker])
  end

  def self.search(params)
    tire.search(page: params[:page], per_page: 5, load: true) do
      query do
        boolean do
          must { string params[:query], default_operator: "AND" } if params[:query].present?
          must { term :authority_name, params[:authority_name] } if params[:authority_name].present?
          must { term :authority_detail_1, params[:authority_detail_1] } if params[:authority_detail_1].present?
          must { term :authority_detail_2, params[:authority_detail_2] } if params[:authority_detail_2].present?

          must { terms 'regulations.regulation_name', params[:regulation_name] } if params[:regulation_name].present?
        end
      end
      facet 'authorities' do
        terms :authority_name
        terms :authority_detail_1
        terms :authority_detail_2
      end
      facet 'regulations' do
        terms 'regulations.regulation_name'
      end
      # raise to_curl
    end
  end

  # other staff

end # end of Class

Но этот код не работает.

После вызова API я получил ошибку:

Tire::Search::SearchRequestFailed in SentencesController#search

{

"error": "SearchPhaseExecutionException[Failed to execute phase [query], total failure; shardFailures {[-ocpucv-TwGCmLfPd3U9hQ][sentences][4]: SearchParseException[[sentences][4]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"bool\":{\"must\":[{\"query_string\":{\"query\":\"appalto\",\"default_operator\":\"AND\"}},{\"terms\":{\"regulations.regulation_name\":\"Cod. civ.\"}}]}},\"facets\":{\"authorities\":{\"terms\":{\"field\":\"authority_detail_2\",\"size\":10,\"all_terms\":false}},\"regulations\":{\"terms\":{\"field\":\"regulations.regulation_name\",\"size\":10,\"all_terms\":false}}},\"size\":5,\"from\":0}]]]; nested: }{[-ocpucv-TwGCmLfPd3U9hQ][sentences][0]: SearchParseException[[sentences][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"bool\":{\"must\":[{\"query_string\":{\"query\":\"appalto\",\"default_operator\":\"AND\"}},{\"terms\":{\"regulations.regulation_name\":\"Cod. civ.\"}}]}},\"facets\":{\"authorities\":{\"terms\":{\"field\":\"authority_detail_2\",\"size\":10,\"all_terms\":false}},\"regulations\":{\"terms\":{\"field\":\"regulations.regulation_name\",\"size\":10,\"all_terms\":false}}},\"size\":5,\"from\":0}]]]; nested: }{[-ocpucv-TwGCmLfPd3U9hQ][sentences][1]: SearchParseException[[sentences][1]: from[-1],size[-1]: Parse Failure [Failed to parse source [{\"query\":{\"bool\":{\"must\":[{\"query_string\":{\"query\":\"appalto\",\"default_operator\":\"AND\"}},{\"terms\":{\"regulations.regulation_name\":\"Cod. civ.\"}}]}},\"facets\":{\"authorities\":{\"terms\":{\"field\":\"authority_detail_2\",\"size\":10,\"all_terms\":false}},\"regulations\":{\"terms\":{\"field\":\"regulations.regulation_name\",\"size\":10,\"all_terms\":false}}},\"size\":5,\"from\":0}]]]; nested: }]",
"status": 500

}

И здесь ошибка JSON проанализирована в более "читаемую форму":

nested: }]

Есть идеи, как правильно реализовать ассоциацию has_many в Tire?

PS И ДА, я запустил грабли после смены шин.

РЕДАКТИРОВАТЬ:

ХОРОШО. Я исправил 500 ошибка при изменении одной строки в коде (термин => термин).

  must { term 'regulations.regulation_name', params[:regulation_name] } if params[:regulation_name].present?

Но теперь мои результаты поиска пусты? Кто-нибудь знает, как это исправить? Возможно, я должен использовать другой вид матча (в настоящее время я использую boolean + must комбо).

Answer 1

У меня была опечатка. Когда я исправил это все работает нормально.

Я опубликую четкий код для других пользователей
