Foundation Rails 2

You’ve heard about this amazing web framework called Ruby on Rails that’s taken the world by storm but thought it was way too complex for you? Think again.

Foundation Rails 2 takes you through your first steps in Rails, explaining in plain English how to start building dynamic web applications. And there’s never been a better time to jump in to the Rails world, as the release of Rails 2 is a major evolutionary leap forward from previous versions.

Unlike other Rails books, this book doesn’t throw you into the deep end right away in the hopes that you’ll learn to swim. Instead, we’ll start out with the basics and continually expand your knowledge until, by the end of the book, we’re building a Rails application with dynamic features such as user registration, geocoding, filtering results with AJAX, RSS feeds, and an XML interface. Meanwhile, we’ll talk about the important issues that other books often leave out such as testing your application’s code, securing your application from hackers, optimizing your code for the best performance, and of course, deploying your application.

This book takes a focused approach to guiding you through understanding how the pieces of Rails work individually and how they fit together. Instead of emphasizing boring theoretical discussions, Foundation Rails 2 lets you get your hands dirty with the framework and learn the hows and whys of Rails faster than ever.

We start with a tour of what makes Rails special and why you need to learn it, move into a gentle introduction to the high points of programming in Ruby, and then take a tour of a sample Rails application. Next, we dig deeper into the core components of Rails before building a complete Rails application together. By the end of this book, not only will you know how to build Rails applications but you’ll understand the reasons behind what you do.

In this book, you’ll learn

The foundations of the Ruby programming language

The most important Rails philosophies and conventions that speed up web development

How to make working with databases easy and fun using ActiveRecord

Automated testing with RSpec to ensure your applications are rock solid

How to build a complete Rails application with special discussions on security, performance, and deployment

Simply Rails 2

Want to learn all about Ruby on Rails 2.0, the web application framework that is inspiring developers around the world?

The 2nd edition of this practical hands-on guide for first-time Ruby on Rails programmers will walk you through installing the required software on a Windows, Mac or Linux computer. And before you get coding, an entire chapter is devoted to object oriented programming in Ruby, so you’ll be completely confident with the Ruby language before you begin working with Rails.

The example application that the book builds – a user-generated news web site – is built upon with each following chapter, and concepts such as sessions, cookies and basic AJAX usage are gradually introduced. Different aspects of Rails, such as user authentication, session cookies, and automated testing are explored with each feature that is added to the application.

The book finishes with chapters on debugging, benchmarking and deployment to a live web server.

By the end of the book, you’ll have built a fully-featured Web 2.0 application and deployed it to the Web. And all code is up-to-date for Rails 2.0, so you can begin coding immediately with the latest version of Rails.

Information

About Rails Versions

This book is written for Rails 2. As this printing of the book is going to press,the current generally available Gem version of Rails is 2.1. The code in this

book has been tested against this version.

This book started life with the same text as the Second Edition, which covered Rails 1.2.6. Pages containing this original text have a gray heading and

footer. As we migrate content to Rails 2, you’ll find the header color changes to red. The Third Edition preface contains a table summarizing the status

of this update process. In particular, note that in many of the chapters the screenshots have not yet been updated to match the results produced by

Rails 2.1.

The Rails core team is continuing to work on Rails 2. From time to time, new releases may introduce incompatibilities for applications written for prior

versions of Rails. In order to experiment with these changes, the Rails developers are making the changes available via Edge Rails (discussed starting on

page 244). These changes won’t affect you unless you explicitly install this experimental code—you won’t find yourself running it unless you overide

Gem defaults or deliberately choose to use Edge Rails. However, if you do decide to run this experimental Rails code, you’ll find that some stuff in this

book (and some stuff in your existing Rails applications) may no longer run. To determine the version of Rails that you are running, you can issue rails -

at a command prompt.
