polling with delayed_job

Question

I have a process which takes generally a few seconds to complete so I\'m trying to use delayed_job to handle it asynchronously. The job itself works fine, my question is ho

Answer 1

I think that the best way would be to use the callbacks available in the delayed_job. These are: :success, :error and :after. so you can put some code in your model with the after:

class ToBeDelayed
  def perform
    # do something
  end

  def after(job)
    # do something
  end
end

Because if you insist of using the obj.delayed.method, then you'll have to monkey patch Delayed::PerformableMethod and add the after method there. IMHO it's far better than polling for some value which might be even backend specific (ActiveRecord vs. Mongoid, for instance).
