-# app/models/delayed_job.rb
-class DelayedJob
-  include Mongoid::Document
-  include Mongoid::Timestamps
-
-  field :priority, :type => Integer, :default => 0      # Allows some jobs to jump to the front of the queue
-  field :attempts, :type => Integer, :default => 0      # Provides for retries, but still fail eventually.
-  field :handler                      # YAML-encoded string of the object that will do work
-  field :last_error                   # reason for last failure (See Note below)
-  field :run_at, :type => DateTime                       # When to run. Could be Time.zone.now for immediately, or sometime in the future.
-  field :locked_at, :type => DateTime                    # Set when a client is working on this object
-  field :failed_at, :type => DateTime                    # Set when all retries have failed (actually, by default, the record is deleted instead)
-  field :locked_by                    # Who is working on this object (if locked)
