How to enqueue a job within a job dynamically in Rails?

Question

I've a job, and when the job is run, at the very bottom of it, and I want to enqueue the same job again to run after 1 hour, but with different arguments.

What I've achieved so far:

class SimpleJob
  @queue = :normal

  def self.perform(start)
    puts "Right now, start = #{start}"
    start += 12
    time = some_request_external_api
    self.set(wait: time).perform_later(start)
  end
end

I'm using resque gem, and running the job through QUEUE=* rake resque:work. Surely, it prints Right now, start = 12 in beginning, but after that, nothing happens. How exactly can I achieve this functionality?

Answer 1

Rather than enqueuing the job again within itself, you could either use a scheduler, such as clockwork.

Or, if what you are trying to accomplish is in response to some event on another service, maybe you could look into it's documentation and see if it provides webhook functionality.

These would send post requests to your desired action whenever any action occurs on their side.
