Send notification to user after a while Rails

I have this scenario: A user buys a product and when two days have passed after the transaction has been processed, I need to send a mail notification to buyer.

At this moment my idea is to use whenever gem and check build a cron job to check in each day and if 2 days have passed and if true, cron job will send mail notification.

I don't know if is ok to do this... Can you give me better solution?

Solution

  • You can use ActiveJob with perform_later, like:

    NotificationSendJob.set(wait: 2.days).perform_later(record)

    Note that not all backends support this. You can see check feature matrix here: http://api.rubyonrails.org/classes/ActiveJob/QueueAdapters.html
