This book's emphasis is on using Rails to build a large database-backed web application---precisely the kind of applications for which Rails is perfectly suited. The application built in this book is a social-networking website à la Facebook or MySpace. This represents four principal advantages. First, social networking is a hot topic and is currently generating a high degree of excitement. Second, a social networking application is big, giving the authors a chance to show off the features Rails has to handle the complexity of large projects, including the Model-Controller-View (MVC) architecture, automated testing, and code refactoring. Third, the application matches the authors' expertise: Aurelius Prochazka has considerable experience with community websites as a founder of ArsDigita, a pioneer in the development of social networking sites as early as 1999, and Michael Hartl cofounded a company to develop sports applications with a strong social component. Finally, the step-by-step tutorial approach allows users see Rails as it is actually used, resulting in learning by example. The book will have an extensive website of supporting materials at RailsSpace.com, including the application source code, a tech blog, screencasts, follow-up articles, and a working version of the social network "RailsSpace" itself. Product Description
Ruby on Rails is fast displacing PHP, ASP, and J2EE as the development framework of choice for discriminating programmers, thanks to its elegant design and emphasis on practical results. RailsSpace teaches you to build large-scale projects with Rails by developing a real-world application: a social networking website like MySpace, Facebook, or Friendster.
Inside, the authors walk you step by step from the creation of the site's virtually static front page, through user registration and authentication, and into a highly dynamic site, complete with user profiles, image upload, email, blogs, full-text and geographical search, and a friendship request system. In the process, you learn how Rails helps you control code complexity with the model-view-controller (MVC) architecture, abstraction layers, automated testing, and code refactoring, allowing you to scale up to a large project even with a small number of developers.
This essential introduction to Rails provides
A tutorial approach that allows you to experience Rails as it is actually used
A solid foundation for creating any login-based website in Rails
Coverage of newer and more advanced Rails features, such as form generators, REST, and Ajax (including RJS)
A thorough and integrated introduction to automated testing
The book's companion website provides the application source code, a blog with follow-up articles, narrated screencasts, and a working version of the RailSpace social network.
