“Whenever” gem running cron jobs on Heroku

Question

I created an app that uses the whenever gem. The gem creates cron jobs. I got it working locally but can\'t seem to get it working on heroku cedar. What\'s the command to do

Answer 1

You need to add Heroku Scheduler addon.

You can add it directly from your dashboard or using following commands:

1. install the add-on:

   heroku addons:create scheduler:standard
   

2. Create a rake task in lib/tasks

   # lib/tasks/scheduler.rake
   task :send_reminders => :environment do
     User.send_reminders
   end
   

3. Schedule job

   • Visit Heroku Dashboard
   • Open your app
   • Select Scheduler from add-ons list

   • Click Add Job, enter a task and select frequency.

     e.g. Add rake send_reminders, select "Daily" and "00:00" to send reminders every day at midnight.
