example showing possible Rufus production env quirks

schedule.rb

# Example of how I'm using Rufus. I'm basically starting a scheduler, then
# using my backend to persist the job_id for the option to cancel it later.

# config/initializers/schedule.rb
SCHEDULER = Rufus::Scheduler.start_new

scrapers_controller.rb

# app/controllers/scrapers_controller.rb
class ScrapersController < ApplicationController
  def start
    scraper = Scraper.find(params[:id])
    job = SCHEDULER.every '1s' do
      Resque.enqueue(Worker, data.next) # You get the point
    end

    # This is needed only in my production environment...
    SCHEDULER.start

    scraper.job_id = job.job_id
    scraper.save
  end

  def stop
    scraper = Scraper.find(params[:id])

    # Interestingly, this doesn't work in production either...
    SCHEDULER.unschedule(scraper.job_id)

    scraper.job_id = nil
    scraper.save
  end
