Create Recurring job using delayed job

basically delayed job is using for background job. but we can use it as a recurring job.
here’s the step

first, install delayed_ojb gem. you can see how to install it at
http://github.com/collectiveidea/delayed_job

then add a new library to your rails apps directory ( /Libs ) e.g: jobs.rb

module Jobs
  module ScheduledJob
    def self.included(base)
      puts "WORK !!!"
      base.extend(ClassMethods)
    end

    def perform_with_schedule
      Delayed::Job.enqueue self, 0, self.class.schedule.from_now.getutc
      perform_without_schedule
    end

    module ClassMethods
      def method_added(name)
        if name.to_s == "perform" && !@redefined
          @redefined = true
          alias_method_chain :perform, :schedule
        end
      end

      def schedule
        @schedule
      end

      def run_every(time)
        @schedule = time
      end
    end

  end
end

after that, you can include your job class to your delayed_job script :

class recurring_job
include ScheduledJob

run_every 1.hours

  def perform
    puts "perform job"
  end
end

then run the job in the console :
RAILS_ENV=production script/delayed_job start
rake jobs:work

stop the job :
RAILS_ENV=production script/delayed_job stop
