After finishing Ruby on Rails Tutorial, I recommend that newer programmers read Beginning Ruby by Peter Cooper, which shares the same basic instructional philosophy as Rails Tutorial I also recommend The Ruby Way by Hal Fulton Finally, to gain a deeper understanding of Rails, I recommend The Rails 3 Way by Obie Fernandez Web applications, even relatively simple ones, are by their nature fairly complex If you are completely new to web programming and find Rails Tutorial overwhelming, it could be that you re not quite ready to make web applications yet In that case, I d suggest learning the basics of HTML and CSS and then giving Rails Tutorial another go (Unfortunately, I don t have a personal recommendation here, but Head First HTML looks promising, and one reader recommends CSS: The Missing Manual by David Sawyer McFarland) You might also consider reading the first few chapters of Beginning Ruby, which starts with sample applications much smaller than a full-blown web app Experienced programmers new to web development: Your previous experience means you probably already understand ideas like classes, methods, data structures, etc, which is a big advantage Be warned that if your background is in C/C++ or Java, you may find Ruby a bit of an odd duck, and it might take time to get used to it; just stick with it and eventually you ll be fine (Ruby even lets you put semicolons at the ends of lines if you miss them too much) Rails Tutorial covers all the web-specific ideas you ll need, so don t worry if you don t currently know a PUT from a POST Experienced web developers new to Rails: You have a great head start, especially 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 Experienced Ruby programmers: The set of Ruby programmers who don t know Rails is a small one nowadays, but if you are a member of this elite group you can fly through this book and then move on to The Rails 3 Way by Obie Fernandez Inexperienced Rails programmers: You ve perhaps read some other tutorials and made a few small Rails apps yourself Based on reader feedback, I m confident that you can still get a lot out of this book Among other things, the techniques here may be more up to date than the ones you picked up when you originally learned Rails

Experienced Rails programmers: This book is unnecessary for you, but many experienced Rails developers have expressed surprise at how much they learned from this book, and you might enjoy seeing Rails from a different perspective After finishing Ruby on Rails Tutorial, I recommend that experienced (non-Ruby) programmers read The Well-Grounded Rubyist by David A Black, which is an excellent in-depth discussion of Ruby from the ground up, or The Ruby Way by Hal Fulton, which is also fairly advanced but takes a more topical approach Then move on to The Rails 3 Way to deepen your Rails expertise At the end of this process, no matter where you started, you will be ready for the more intermediate-to-advanced Rails resources Here are some I particularly recommend:

Before moving on with the rest of the introduction, I d like to take a moment to address the one issue that dogged the Rails framework the most in its early days: the supposed inability of Rails to scale ie, to handle large amounts of traffic 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 So the real question should have been, Can a site built with Rails scale In any case, the question has now been definitively answered in the affirmative: some of the most heavily trafficked sites in the world use Rails Actually doing the scaling is beyond the scope of just Rails, but rest assured that if your application ever needs to handle the load of Hulu or the Yellow Pages, Rails won t stop you from taking over the world
