Rails / delayed_job - want to load newest version of job class

Question

I\'m using the delayed_job plugin in Rails to do background processing, and I\'m experiencing a hiccup in the \'agile development\' I\'ve been experiencing so far in Rails..

Answer 1

I use this hack that seams to work quite nice, but be aware that it's probably very Rails and delayed_job version specific so you probably need to change some things. Tested with Rails 3.2.0 and delayed_job 2.1.4.

Put this into e.g. script/delayed_job_development and run it from the Rails root.

#!/usr/bin/env ruby

require File.expand_path('../config/environment', File.dirname(__FILE__))
require 'delayed/worker'
require "rails/console/app"

class DummyConsoleClass
  include Rails::ConsoleMethods
end
dummy_console = DummyConsoleClass.new

worker = Delayed::Worker.new({:quiet => false})

puts "Waiting for jobs..."
loop do
  if Delayed::Job.find_available(worker.name).count > 0
    puts "Found jobs"
    dummy_console.reload!
    loop do
      break if worker.work_off.sum == 0
    end
    puts "Done, waiting for jobs..."
  end
  sleep(2)
end

Please comment if you know that this is a very bad idea or things to be aware of, I mainly use it when editing and testing jobs that run immediately not with jobs scheduled to run long into the future.
