“Ruby on Rails™ 3 Tutorial: Learn Rails by Example by Michael Hartl has become a must read for developers learning how to build Rails apps.”
—Peter Cooper, Editor of Ruby Inside
Using Rails 3, developers can build web applications of exceptional elegance and power. Although its remarkable capabilities have made Ruby on Rails one of the world’s most popular web development frameworks, it can be challenging to learn and use. Ruby on Rails™ 3 Tutorial is the solution. Leading Rails developer Michael Hartl teaches Rails 3 by guiding you through the development of your own complete sample application using the latest techniques in Rails web development.
Drawing on his experience building RailsSpace, Insoshi, and other sophisticated Rails applications, Hartl illuminates all facets of design and implementation—including powerful new techniques that simplify and accelerate development.

An excellent resource in a wilderness of hell,
Amazon Verified Purchase(What's this?)
This review is from: Ruby on Rails 3 Tutorial: Learn Rails by Example (Addison-Wesley Professional Ruby Series) (Paperback)There are as many rails tutorials on the web and in book form as there are ruby methods. An infinite expanse of information - most of it leading to heartbreak and frustration.
Hartl, with this book as well as the first venture, takes the reader by the hand and gently guides him/her/it/them/monkeybacon through the world of ruby and ruby on rails with the excitement and ease a master has when taking students along for a ride.
I have a collection of books and tutorials and, WITHOUT FAIL, each and every one of them ends somewhere with some sort of mistake in code that I've never been able to get over (including the first book by Hartl, by the way). Not so with this one. I completed the project outlined in this book. First time that's happened with any of the other books/tutorials.
As I am a functioning idiot, this is no mean feat. It is quite an accomplishment. Not by me, but by the author.
If you are able to view the tutorial videos, those will... Read more

Great book but poor Kindle version,
Amazon Verified Purchase(What's this?)
This review is from: Ruby on Rails 3 Tutorial: Learn Rails by Example (Addison-Wesley Professional Ruby Series) (Kindle Edition)This is an exceptionally well-written tutorial, probably the best way to learn Ruby on Rails. The Kindle version, however, is very poorly done. Code listings are shown as images on the Kindle -- with small grey font which is very difficult to read even when zoomed-in. Furthermore, text search does not include the code listings and command examples. For example, I needed to find an explanation of the command "rake db:test:prepare" but got back "0 matches found".
Though the Kindle edition is awful, the excellent content is accessible on web pages for free at [...]. There, one can also purchase a (fully searchable) PDF version directly from the author.
I don't know whether it's Amazon's or the publisher's fault, but the Kindle edition of this book is a complete waste of money.

A must-read for any RoR novice,
This review is from: Ruby on Rails 3 Tutorial: Learn Rails by Example (Addison-Wesley Professional Ruby Series) (Paperback)While there are tons of other RoR tutorials out there, they all usually reach a point where the gently increasing learning curve suddenly goes vertical. Not so with this book.
The author doesn't make things overly complicated, makes it clear when you need to be aware of new concepts and when not to worry (because it'll be covered later), and while this book does follow the traditional "develop an app while learning" method, it does so while introducing you to tools and techniques that Rails developers use in the real world. Before you know it, you'll be creating new git repos, pushing them to Github, creating branches for new developments and using test driven development (with tools like Rspec) to test your new code. If most of that went over your head *and* you want to learn Rails, you *need* this book.
Interestingly, he demonstrates how you can create working Rails apps with a minimal knowledge of Ruby - which kills the assumption that Rails neophytes need to... Read more
