Question

我从Tire迁移到Flex 基本搜索和索引同步工作我认为模型中的flex.parent线会自动创建_parent映射，但它会崩溃我无法找到任何父/子演示项目。

Flex.yml：

settings:
  number_of_shards: 5
  number_of_replicas: 1
  # analysis:
    # analyzer:
    # tokenizer:
  mappings:
    userprofile:
      startdatef:
        type: 'date'
        format: 'dateOptionalTime'
        fields:
          index: 'not_analyzed'
          untouched:
            type: 'date'
            index: 'not_analyzed'
    orgunit:
      org_name:
        type: 'string'
        index: 'analyzed'
        search_analyzer: orgunit_name_search
        index_analyzer: orgunit_name_index
      untouched:
        type: 'string'
        index: 'not_analyzed'

父模型：

class Userprofile < ActiveRecord::Base
  include Flex::ModelIndexer
  include Flex::Model
  flex.sync self
  has_many :assignments,
    -> { order(startdate: :desc) }, dependent: :restrict_with_exception

  module Search
    include Flex::Scopes
    flex.context = Userprofile
    scope :alla, query([])
  end

  # rubocop:disable all
  def flex_source
    {
      id: id,
      fullname: fullname,
      firstname: firstname,
      lastname: lastname,
      pnr: pnr,
      gender: gender,
      asscount: asscount,
      created_at: created_at,
      updated_at: updated_at,
      user_id: user_id,
      creator_id: creator_id,
    }
  end
  # rubocop:enable all
end

儿童模特：

class Assignment < ActiveRecord::Base
  include Flex::ModelIndexer
  include Flex::Model
  flex.parent :userprofile, 'userprofile' => 'assignment' # This makes indexing break
  flex.sync self, :userprofile
  belongs_to :userprofile, counter_cache: true, touch: true

  module Search
    include Flex::Scopes
    flex.context = Assignment
    scope :alla, query([])
  end

  def flex_source
    {
      # _parent_id: userprofile_id,
      userprofile_id: userprofile_id,
      created_at: created_at,
      updated_at: updated_at
    }
  end
end

rake flex：import

在您的映射中，您必须指定＆＃34; parent＆＃34;领域。只有那时ES才能链接＆＃34; _parent＆＃34;您要索引到相应索引类型的字段。尝试将其作为模板（替换适合您索引的变量）。它只是将信息添加到映射中，而不是删除现有的信息：

curl -XPUT 'http://localhost:9200/$yourIndex/$yourChildTypeName/_mapping' -d '
{
      "$yourChildTypeName" : {
         "_parent" : {
            "type" : "$yourParentTypeName"
         }
} '

然后再次尝试索引。

如何创建父子映射？
