I have a ruby on rails app using the resque gem to process background

  • 0

I have a ruby on rails app using the resque gem to process background jobs. I have users trigger background jobs that can take upwards of 10 minutes to complete (they’re processing a ton of data). What is the best way to alert the user when the job has completed?

I’ve seen the answer here about using resque-status, is that the only solution? Or is there another way to alert the user through normal resque (which I’ve already implemented)?

    If you intend to notify a user asynchronously, you have three options:

    1. Set a flag in the database, and then change your UI the next time they log in. (Like popping in an alert view or something.)
    2. Send them an email at the conclusion of the job’s run. Just use the standard ActionMailer stuff for this.
    3. If you’re using a pubsub framework like Faye or Juggernaut, push the user a notification that the job is done. If they’re signed in they should see it immediately.

    Those are pretty much the only things I can think of. I would personally go with a combination of 1 and 2; send them an email on completion, and notify them (and provide a link in the notification) the next time they log in.
