Question

我将Rails从4升级到5.2，还将elasticsearch从2.4升级到6.8。

以下是我遇到的错误。

[400] {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Fielddata is disabled on text fields by default. Set fielddata=true on [activity_type] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."}]

这是请求*的样子：

activity_types=>{:terms=>{:field=>"activity_type"}}

看看activity_search.rb：

class ActivitySearch < Search::Model
  include DateSearch
  apply_date_filters
  apply_date_aggregations

  filters :activity_types, type: :terms, field: :activity_type, aggregate: false

  aggregates :activity_types, :subject_ids, :levels

  ....

看看model.rb：

module Search
  class Model
    def add_aggregation(name, opts={})
      self._aggregations = _aggregations.deep_merge({name.to_sym => opts})
      return if method_defined? "aggregate_#{name}" 
      define_method "aggregate_#{name}" do |config={}|
      type = config.delete(:type){ :terms }
      field = config.delete(:field){ name.to_s.singularize }
      Search::Aggregation.new(type, field, opts)
    end

    def response
      @response ||= Search::Response.new(search.response)
    end

    def request
      @request ||= build_request
    end

    def search
      @search ||= run_search
    end

    private

    def run_search
      search_class.search(request.params)
    end

    def search_class
      self.class.name.demodulize.gsub('Search', '').safe_constantize
    end

    def build_request
      request = Search::Request.new
      request.query(*queries)
      request.filter(*filters)
      request.aggregate(aggregations)
      request.sort(*sorts)
      request
    end
  end

activity_search_facade.rb：

class Companies::ActivitySearchFacade < SimpleDelegator
  delegate :aggregations, to: :response
end

有人可以帮助解决此错误吗？

请注意，elasticsearch-rails gem版本是6.0.0。

让我知道是否需要更多代码。

* 如何更改此请求，以使其在版本6中正确运行？

更新

基于我收到的错误，是否可以解决此问题？

curl -X GET 'localhost:9200/development_activities'

  "activity_type":{"type":"text" }

如何将其更改为type: "keyword"？ ^

Answer 1

请检查您的Elasticsearch版本，因为elasticsearch-rails的gem版本会遵循elasticsearch版本号，并且当您更新elasticsearch-rails时，它可能无法与早期的Elastic-search版本一起正常工作。

Answer 2

因此活动模型如下：

PHP Fatal error:  Interface 'App\Tests\Unit\TestInterface' not found

这是search_common.rb的样子：

class Activity < ApplicationRecord
  include SearchCommon

所以我刚添加：

module SearchCommon
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model

    after_commit on: [:create, :update] do
      __elasticsearch__.index_document
    end

    after_commit on: [:destroy] do
      __elasticsearch__.delete_document
    end

    index_name [Rails.env, model_name.collection].join('_')
  end
end

在Elasticsearch中设置关键字字段
