我怎样才能在Heroku上安排'每周'工作？ [英] How can I schedule a 'weekly' job on Heroku?

问题描述

现在我想要一份每周工作

strong>，但调度程序插件不允许我每周选择一次。

有关如何完成此操作的任何建议：

• 过去使用rufus调度程序，但它造成了一些问题，所以这不是一个选项。有关详细信息，请参见此处。


• 我正在考虑在日常工作中检查当前日期的事情。有没有人尝试过，并有反馈或知道问题的方法？


• 其他想法非常感谢。

$ b

激活Heroku cron add-并在 app / lib / tasks

中添加 cron.rake 任务b
$ b

激活Heroku调度程序加载项，并在 app / lib / tasks中添加 scheduler.rake 任务

 任务：your_weekly_task => ：如果Time.now.friday，环境做
？ ＃先前的答案：Date.today.wday == 5 
 #do something 
 end 
 end 
  

你甚至可以定义你想要任务运行的日子; o）
（星期五为5）

编辑：顺便说一下，Cron已被弃用，Heroku建议切换到他们的Scheduler插件。尽管如此，这并没有改变每周工作的方法。

编辑2：根据来自sunkencity的反馈调整我的答案。

I have a Rails app deployed on Heroku with the Heroku scheduler add-on successfully working for daily jobs.

Now I want a weekly job, but the scheduler add-on does not allow me a weekly option.

Any suggestions on how I could accomplish this:

• I've tried using rufus-scheduler in the past but it caused me some problems, so that's not an option. See here for detail.
• I'm thinking of something along the lines of checking for current day within a daily job. Has anyone tried it and have feedback or know of issues with the approach?
• Other ideas much appreciated.

解决方案

One approach would be the one of your 2nd bullet point:

activate the Heroku cron add-on, and add a cron.rake task in app/lib/tasks

Activate the Heroku scheduler add-on, and add a scheduler.rake task in app/lib/tasks

task :your_weekly_task=> :environment do
  if Time.now.friday? # previous answer: Date.today.wday == 5
    #do something
  end
end

You even have the luxury of defining the day you want your task to run ;o) (5 is for Friday)

EDIT: by the way, Cron is deprecated and Heroku recommends switching to their Scheduler add-on. This doesn't change the approach for a weekly job though.

EDIT2: adjustments to my answer based on feedback from sunkencity.
