Broadcast every second using websokets-rails gem

I create an application to get some information every second using websockets-rails gem. Right now, it seems that all messages are sent after the method has completed completely.

My websockets controller:

class DbTestsController< WebsocketRails::BaseController

  def run_tests_on_all
    dbtsch = DbTestsScheduler.new
    dbtsch.run(1, 10, message['shard'], :push) do |ops|
      send_message 'db_test.run_tests_on_all', ops
      Rails.logger.info(ops)
    end
  end

end

The 'run' method looks like

def run(ecfs, fafs, shard, operation)
    st = tep_t = Time.now
    while st + fafs.second > Time.now
      Octopus.using(shard) do
        send(operation)
      end
      if tep_t + ecfs.second <= Time.now
        tep_t = tep_t + 1.second
        yield(@ops) if block_given?
        @ops = 0
      end
    end
  end

In the console, I see that it Rails.logger.info(ops)displays a message every second, but send_messagesends all 10 results immediately after the method completes.
