ruby on rails - delayed_job tasks failing in daemon mode in production environment -

i'm trying use delayed_jobs. works perfectly, locally, when using rake jobs:work task. however, when try use daemon, tasks fail. i've stopped deleting failed tasks. i'm starting daemon 'rails_env=production bin/delayed_jobs start'. when status shows worker active.

they seem failing error 'job failed load: undefined class/module productaquisition.'

this snippet module i'm trying use (lib/product_aquisition.rb).

module productaquisition      require 'net/http'      def productaquisition.get_updates          .....     end  end 

this rakefile i'm trying use trigger this

require 'debugger' require 'date' require 'thread' # require 'active_support'  require "#{rails.root}/lib/product_aquisition.rb" require "#{rails.root}/app/helpers/soap_helper" include soaphelper include productaquisition    task :get_updates => :environment      productaquisition.delay.get_updates  end 

i don't understand how it's unable load , use module 'productaquisition' when running daemon. can shed light on this?
