gem 'progress_job'

And then execute:

$ bundle

$ rake progress_job:install

Usage

Create a new class that extends ProgressJob::Base

class NewJob < ProgressJob::Base

  def perform
    10.times do |i|
      sleep(1.seconds)
      update_progress(step: 10)
    end
  end

end

Inside perform method you can use 'update_progress(step)' method to update the job progress.

To create a new job use Delayed job enqueue method, and pass the progress_max value

job = Delayed::Job.enqueue NewJob.new(100)

There is also a controller which returns the delayed job with calculated percentage

GET 'progress-jobs/:job_id/'

$('.button').click(function(){

  var interval;
  $.ajax({
    url: '/start',
    success: function(job){
      interval = setInterval(function(){
        $.ajax({
          url: '/progress-jobs/' + job.id,
          success: function(job){
            $('.progress-bar').css('width', job.progress + '%').text(job.progress + '%')
          },
          error: function(){
            $('.progress-bar').css('width', '100%').text('100%')
