如何创建父子映射？

我从Tire迁移到Flex Basic搜索和索引同步工作我认为模型中的flex.parent行会自动创建_parent映射,但它崩溃了我无法找到任何父/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
