You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: runner_manager_type.rb
    path of file: ./repos/gitlabhq/app/graphql/types/ci
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Types
  module Ci
    class RunnerManagerType < BaseObject
      graphql_name 'CiRunnerManager'

      connection_type_class ::Types::CountableConnectionType

      authorize :read_runner_manager

      alias_metho
    
      def job_execution_status
        BatchLoader::GraphQL.for(runner_manager.id).batch(key: :running_builds_exist) do |runner_manager_ids, loader|
          statuses = ::Ci::RunnerManager.id_in(runner_manager_ids).with_running_builds.index_by(&:id)

          runner_manager_ids.each do |runner_manager_id|
            loader.call(runner_manager_id, statuses[runner_manager_id] ? :running : :idle)
          end
        end
      end
