Using BackgrounDRb

Since I'm having so many issues with BackgrounDRb, I thought I should write down how I'm solving issues - I expect some other people are also experiencing! ;)
I'm assuming that you have already installed it, but if not I wrote up some basic notes here.

Monitoring the task queue

# script/console
# MiddleMan.all_worker_info

This will show you what workers are available, and what if they are currently running.

From Code

#!/usr/bin/env ruby

RAILS_ROOT = '.'

#load required rails and backgroundrb files
require File.dirname(__FILE__) + '/../config/boot'
require File.dirname(__FILE__) + '/../config/environment'
require 'erb'
$LOAD_PATH << "#{RAILS_ROOT}/vendor/plugins/backgroundrb/lib"  require "#{RAILS_ROOT}/vendor/plugins/backgroundrb/lib/backgroundrb.rb"     class BackgroundMonitor         def test              begin                  puts "Raw data:"                  puts MiddleMan.all_worker_info                   puts                  puts "Individual:"                  puts MiddleMan.all_worker_info.values.flatten.select { |w|                      puts w[:worker]                        puts "     key = #{w[:worker_key]}"                        puts "  status = #{w[:status]}"       }              rescue                  puts "Some kind of problem occurred..."              end        end  end   monitor = BackgroundMonitor.new  monitor.test 

Installing BackgrounDRb

BackgrounDRb is a job scheduling library for the ruby programming language.

I had a right old ding dong with it when trying to install it into a rails app I'm working on, what with the documentation being a little out of date (I think) plus there being a load of confusing page on the net. In the end what worked for me was:

  # sudo gem install chronic packet
  # cd rails_app
  # script/plugin install http://svn.devjavu.com/backgroundrb/trunk
  # rake backgroundrb:setup
  # rake db:migrate

So far this has worked for me...
