How can I schedule a 'weekly' job on Heroku?

Question

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.

Answer 1

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.
