Ruby on Rails

Chances are, you already know that Rails is a framework for developing database-backed web applications in Ruby. Rails is so popular that many people get into Ruby just so that they can use Rails.

Even if you don’t know much about Rails and its features, you can still follow along on this tour. We’ll focus on the Rails source code, not on the features. Whenever features are important to understand the source code, I’ll take the time to demonstrate them. Although you don’t have to, you might want to get a quick introduction to Rails on its official site if you’re completely new to it.

While touring the Rails source code, I’ll show you the snippets of code I want to focus on. However, you might also want to keep the source code handy to explore it on your own. To do that, you need to install Rails.
