[英]Rails tire(elasticsearch) search through has_many association
[英]How to add facet in Tire (elasticsearch) to has_many association
我想將facet添加到has_many關聯中。
我正在從PostgreSQL全文搜索遷移到elasticsearch。
目前我有以下SQL查詢做搜索(PostgreSQL方式):
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)}")
我看了關於類似問題的答案(HABTM協會)
並用類似的方法實現代碼
-Sentence AR類
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
但是這段代碼不起作用。
調用API后我收到一個錯誤:
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
}
並且這里將JSON錯誤解析為更多'humar可讀形式':

nested: }]
知道如何在Tire中正確實現has_many關聯嗎?
PS和是我在更改輪胎映射后運行了rake任務。
編輯:
好。 我通過更改代碼中的一行(terms => term)修復了500
錯誤。
must { term 'regulations.regulation_name', params[:regulation_name] } if params[:regulation_name].present?
但現在我的搜索結果是空的? 有人知道怎么修這個東西嗎? 也許我應該使用其他類型的匹配(我目前正在使用boolean
+ must
combo)。
我有一個錯字。 當我修復這一切一切正常。
我將為其他用戶發布明確的代碼
-mappings
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 do
indexes :name, :type => :string, :index => "not_analyzed"
end
end
