Redis and Resque

What this guide will cover: the code you will need in order to include Redis and Resque in your Rails app, and the process of creating a background job with Resque.

What this guide will not cover: installing Ruby, Rails, or Redis.

Note: As of this writing I am still using Ruby 1.9.3p374, Rails 3.2.13, Redis 2.6.11, and Resque 1.24.1. I use SQLite in development and Postgres in production.

Background jobs are frustrating if you've never dealt with them before. Over the past few weeks I've had to incorporate Redis and Resque into my projects in various ways and every bit of progress I made was very painful. There are many 'gotchas' when it comes to background workers, and documentation tends to be outdated or scattered at best.
