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: realtime_controller.rb
    path of file: ./repos/realtime-rails/lib/realtime
    
    the code of the file until where you have to start completion: module Realtime
	module Controller
		extend ActiveSupport::Concern

		module ClassMethods
			def realtime_controller(options = {})
          
    
		def store_realtime_session_zmq
			# store session data or any authentication data you want here, generate to JSON data
			session_data = {
					"user_id" => realtime_user_id,
			}

			# todo: merge additional session data passed in
			stored_session_data = JSON.generate(session_data)

			ZmqWrapper.store_session(
				realtime_user_id,
				@realtime_token,
				stored_session_data,
				86400
			)
		end
