Rails swept to world-wide attention in the Spring of 2005. Since then, it has become a serious and popular alternative to traditional интернет development environments such as Java and .NET. Why? Because Rails has the best of both worlds.

You want to write professional-grade applications: Rails is a full-stack, open-source интернет framework, with integrated support for unit, functional, and integration testing. It enforces good design principles, consistency of code across your team (and across your organization), and proper release management.

But Rails is more than a set of best practices. Rails also makes it both fun and easy to turn out very cool интернет applications. Need Ajax support, so your интернет applications are highly interactive? Rails has it built in. Want an application that sends and receives e-mail? produces and consumes интернет services? supports meaningful URLs? All built-in.

With this book, you’ll learn how to use ActiveRecord to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. Need to create and modify your schema? Migrations make it painless (and they’re versioned, so you can roll changes backward and forward). You’ll learn how to use the Action Pack framework to route incoming requests and render pages using easy-to-write templates and components. See how to exploit the Rails service frameworks to send emails, implement интернет services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There are extensive chapters on testing, deployment, and scaling.

As with the first edition of the book, we start with an extended tutorial that builds parts of an online store. This application has been completely rewritten from the first edition to highlight the new features of Rails.
