Active Record Associations in Rails
Most of your Rails models are going to be connected to other models in some way. An Author has many Articles, and each Article belongs to an Author. A Doctor has many Patients, and a Patient may have many Doctors as well. Rails uses associations to make it easy to track these relationships in your database.

Deployment with Capistrano
Deploying a web app to a production server involves steps that you're going to need to repeat every time you release a new version, such as pulling the changes from Git and restarting your web server. Doing it manually may not seem too bad at first, but over time the potential for mistakes adds up. So in this course, we're going to show you how to automate deploys to make them fast, easy, and safe. We'll be using the Ruby community's most popular deployment framework, Capistrano.

Rails Servers with Unicorn and Nginx
In this workshop, we're going to show you how to set up a "reverse proxy" between your Rails app and the Internet at large. We've going to use a high-performance web server called Nginx as our reverse proxy. Nginx will also serve the static files in our app's "public/" directory, so Rails doesn't have to. We'll also set up Unicorn, an HTTP server that will manage connections to your actual Rails app. Unicorn is good for your site's stability and speed.
