Ruby 延迟的\u作业，从延迟的方法中发送邮件

我有一个延迟方法async\u checkout\u assist，它按预期运行，添加到表中并执行，没有任何问题，执行后从表中删除，但在该延迟方法中，如果条件为真，我希望发送邮件，但当我添加邮件程序行时，它不会发送邮件：\

现在这两种方法都适用

1.是否在延迟作业表中创建任务？2.您确定已启动延迟作业辅助进程来处理作业吗？是的，我已重新启动该辅助进程，然后该辅助进程将async_checkout_assist方法添加到表中并成功运行，但当该方法运行时，它不会发送邮件。它现在似乎可以工作了：|不知道，我再次重新启动了应用程序和该辅助进程，似乎是他干的

class ApplicationController < ActionController::Base

  async = ApplicationController.new #create new instance
  async.async_checkout_assist #call method

  def async_checkout_assist
    Mailer.delay.mailer_checkout_assist(@contact_name, @contact_email, @contact_tel)
  end

  end
  handle_asynchronously :async_checkout_assist, :run_at => Proc.new { 10.seconds.from_now }

end
