ruby-on-rails - 更改has_many模型时的Rails Elasticsearch重新索引文档

Question

我正在使用elasticsearch-rails gems

gem 'elasticsearch-model', '~> 0.1.6'
gem 'elasticsearch-rails', '~> 0.1.6'

我的模型:

place.rb

class Place < ActiveRecord::Base
   include PlaceElasticSearch
   ...
   has_many :order_rooms
   ...
end

orer_room.rb

class OrderRoom < ActiveRecord::Base
  belongs_to :place
end

place_elastic_search.rb

require 'elasticsearch/model'

module PlaceElasticSearch
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks

    index_name "places-#{Rails.env}"

    settings INDEX_SETTINGS do
      mappings dynamic: 'false' do
        ...
        indexes :order_rooms, type: 'nested', include_in_root: true do
          indexes :max_persons,          type: 'integer'
        end
      end
    end

    after_touch() { __elasticsearch__.index_document }

  end
end

创建/删除/更新order_room之后，我需要重新索引放置Elasticsearch文档。

我为order_room模型添加了after_save回调

order_room.rb

after_save :update_place_document

def update_place_document
  place.__elasticsearch__.index_document if Place.respond_to?('__elasticsearch__')
end

但是，如果我已经更新或删除了旧的订购室，那是行不通的。

有任何想法吗？我哪里错了？

Answer 1

嗯，好像地方已经缓存了命令室对象。如果我将重新加载添加到after_save方法或place(cache: false)中，则所有方法均有效。还需要添加after_destroy回调

order_room.rb

after_save :update_place_document
after_destroy :update_place_document

def update_place_document
  place(cache: false).__elasticsearch__.index_document if Place.respond_to?('__elasticsearch__')
end
