Ruby module help

In the code below, I am able to call BackgroundJob.starting(job_script) just fine. However, I keep getting no method error for starting when I try to call JobScriptHelper.starting(RemoveBotReferralCodes), for example. The JobScriptHelper is in the lib folder, while RemoveBotReferralCodes is in a peer folder called script. Any idea what's going on?

module JobScriptHelper

  def starting(job_script)
    puts "#{Time.now.strftime('%c')}: #{job_script.name} - starting"
  end

end



require 'job_script_helper'

    class BackgroundJob < ActiveRecord::Base

      extend JobScriptHelper

    end



#!/usr/bin/env ruby
require File.expand_path('../../../config/boot',  __FILE__)
require File.join(File.expand_path('../../../config/environment', __FILE__))
require 'job_sc开发者_开发知识库ript_helper'

class RemoveBotReferralCodes
  def self.remove
    # .... 
  end
end

JobScriptHelper.starting(RemoveBotReferralCodes)

To be able to call JobScriptHelper.starting() I believe your method definition should be

def JobScriptHelper.starting(job_script)
  puts "#{Time.now.strftime('%c')}: #{job_script.name} - starting"
end
