Run method periodically in manualy created interval in Rails

Question

I have a form when user can set day in week and time period (for example Monday from 02:00 to 03:00). Then I want to run specific method (periodically, for example every 30 seconds) but only during given time interval (it should be performed on background every Monday during 02:00 and 03:00, every 30 seconds). Is it possible to do this when time interval is created dynamically (by user)?

你可以定义一个运行rake任务的cron作业（参考这个语法糖：https://github.com/javan/whenever）。 您的rake任务可以每X秒运行一次，并在数据库中查询新的作业。

但是，通过cron调用rake任务每次都会启动rails应用程序，因此更加苛刻的方法是将sidekiq（http://sidekiq.org/）与sidekiq-scheduler（https://github.com/moove-it/sidekiq-scheduler）结合使用。 / p>
