ruby - Rails delayed job not working

My delayed job is not working. I am trying to create an background task for a rake file using a delayed job that should run every 15 minute. I have copied my rake tasks in my rake file and set them in my controller as methods. I need an delayed job because heroku only makes a cron every 1 hour.

Here is my Application controller:

class ApplicationController < ActionController::Base

require 'delayed_job'
require 'Mechanize'
require 'pp'

def iqmedier
          agent = WWW::Mechanize.new
          agent.get("http://www.iqmedier.dk")
          form = agent.page.forms.first
          form.submit

          agent.page.link_with(:href => "/Publisher/Stats").click

          form = agent.page.forms.first
          form.submit

          @stats = agent.page.search('//tr')[-2]

If I understand correctly what you're trying to do, then you should have the following:

scraper.rb


require 'mechanize'

class Scraper
  def perform
    [:iqmedier, :euroads, :mikkelsen, :orville].each{|a| send(a)}
  end

  def iqmedier
    # some code
  end

  def mikkelsen
    # some code
  end

  def orville
    # some code
  end

end

in your controller:


require 'delayed_job'
class MyController < ApplicationController
  def runall
    Delayed::Job.enqueue(Scraper.new, :run_at => 5.minutes.from_now)
  end
end

For adding jobs from outside of rails, you can write something similar and then run it with rails runner:


require 'scraper'
Delayed::Job.enqueue Scraper.new
Delayed::Job.enqueue Scraper.new, :run_at => 15.minutes.from_now
Delayed::Job.enqueue Scraper.new, :run_at => 30.minutes.from_now
Delayed::Job.enqueue Scraper.new, :run_at => 45.minutes.from_now
