创建Rails会话后启动间隔任务（用户登录）？

Question

我基本上想在用户登录时创建一个计划任务。这是什么Rails实用程序，gem等？ 基本上，Rails服务器需要根据一组条件每两分钟向浏览器用户发出一次警报。 此任务必须在会话上结束#destroy

在会话中控制器

def new
 @user = User.authenticate(params[:session][:email], params[:session]  [:password])
if @user 
 session[:@user_id] = @user.id
 #how do i create a scheduled task for this session? I have a #current_user Application Controller method that will find #sessions[:@user_id] and identify it as the current user.

end
end


def destroy

sessions[:@user_id] = nil
#need to end scheduled task here.

end

要完成Rails中想要的功能，可以使用Thread 。

# create thread

my_thread = Thread.new do

  # do some junk

  # put thread to sleep for 120 seconds

  sleep(120)
end

# nuke the thread on session#destroy

my_thread.kill
