Happy Tau Day! With the release of this new edition, the Ruby on Rails Tutorial continues to be the most comprehensive and up-to-date resource for learning web development with Rails. As with previous editions, its focus is on the general principles of web development, not on Rails specifically, though of course it gives you a great foundation with Rails as well. Although there are many alternatives in web development, I believe Rails is still the best overall choice for learning how to develop dynamic web applications. Rails has a combination of power and maturity that few frameworks can rival, and is used by companies as diverse as GitHub, Disney, and Airbnb.

The exercises are the minibosses. Fol- lowing the scaffolding approach risks turning you into a virtuoso script generator with little and brittle actual knowledge of Rails.

At each stage of developing the sample application, we will write small, bite-sized pieces of code—simple enough to understand, yet novel enough to be challenging.

There are also many web development shops that specialize in Rails, such as ENTP, thoughtbot, Pivotal Labs, and Hashrocket, plus innumerable independent consultants, trainers, and contrac- tors. What makes Rails so great? Rails also adapts rapidly to new developments in web technology and frame- work design. The comments below contain some suggestions for approaching the Rails Tu- torial depending on your background.

The answer depends on your personal learning style and how much 1. On the other hand, many beginning Rails developers are excited about making web applications, and would rather not slog through a page book on pure Ruby before ever writing a single web page.

In this case, I recommend following the short interactive tutorial at Try Ruby,2 and then optionally do the free tutorial at Rails for Zombies3 to get a taste of what Rails can do.

Another common question is whether to use tests from the start. Inexperienced programmers: The Rails Tutorial is not aimed principally at beginning programmers, and web applications, even relatively simple ones, are by their nature fairly complex.

Experienced programmers new to web development: Your previous experi- ence means you probably already understand ideas like classes, methods, data structures, etc. Ruby even lets you put semicolons at the ends of lines if you miss them too much. Experienced web developers new to Rails: You have a great head start, es- pecially if you have used a dynamic language such as PHP or even better Python.

The basics of what we cover will likely be familiar, but test-driven development may be new to you, as may be the structured REST style favored by Rails.

Ruby has its own idiosyncrasies, so those will likely be new, too.

Among other things, the techniques here may be more up-to-date than the ones you picked up when you originally learned Rails. At the end of this process, no matter where you started, you should be ready for the many more intermediate-to-advanced Rails resources out there.

Part of this issue relied on a misconception; you scale a site, not a framework, and Rails, as awesome as it is, is only a framework. Related Papers. The screencasts are available for download from the Rails Tutorial website or if you have a subscription from Safari Books Online.

I try always to include enough detail that even a beginner has a place to start if they need further information.

Tech is the new literacy

If not, what is the speediest way for a Rails developer to progress from here aside from reading the API which many suggest? The book is easy to edit, but the screencasts are trickier, so for a while I might only supplement the screencasts. Eventually, though, I anticipate having to re-cut the entire series once Rails has changed enough to justify the effort.

Most Ruby web frameworks, including Rails and Sinatra, use Rack, and it is certainly important in some contexts, but I think that Rack can be skipped when first learning Rails. Have you cashed in on the notoriety yet!? It is weird, though, and disappointing.

In that book, my coauthor and I made the mistake of not using specific version numbers for the gems, but the Ruby on Rails 3 Tutorial book avoids this error. Every one of the gems in the book is tied to a particular version number, so the tutorial is virtually guaranteed to work as advertised.

Of course, I do occasionally update the book with new gem versions, but I always test the new gems to make sure they work.
