how to query delayed_job handler

I'm playing with delayed_job and I need to delete all the job with a specified handler value, I tried in this way

class Auction < ActiveRecord::Base
  def clean_jobs
    Delayed::Job.all.each do |job|
      job.delete if job.payload_object.auction_id == id
    end
  end
end

and it works but I have to go through the entire queue...not cool. How can i work around this? Thank you
