  include Sidekiq::Worker
  require 'sk_progress_bar'

  def perform
    objects = [*1..10]
    # objects => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    start_cycle(objects)
  end

  def start_cycle(objects)
    objects.each_with_index do |object, index|
      sleep(0.5)

      progress = SkProgressBar.progress_status(index, objects.count)
      # progress => {:percentage=>10, :message=>"Almost done"}
      # jid => Sidekiq Process ID (46b26c4df9a6c0e2603552bf)

      SkProgressBar.update_progress_bar(progress[:percentage], progress[:message], jid)
      # Update Html Progress Bar
      
      SkProgressBar.create_update_db(progress[:percentage], progress[:message], jid)
      # Create/Update Record in DB
    end
  end
end

Rails console

ProgressBarWorker.perform_async
or
ProgressBarWorker.new.perform

# Important (Only for ".new.perform")
    When you are using the method ".new.perform" in SidekiqWorker and you need to use 
    "SkProgressBar.create_update_db" method to save results in DB, please add a unique 
    "jid" variable in order to avoid duplicated records in the DB.
    
    "Example: SkProgressBar.create_update_db(progress[:percentage], progress[:message], jid)"
