Rails is a fullstack, opensource web framework that enables you to create fullfeatured, sophisticated webbased applications, but with a twist... A full Rails application probably has less total code than the XML you`d need to configure the same application in other frameworks. With this book you`ll learn how to use ActiveRecord to connect business objects and database tables. No more painful objectrelational mapping. Just create your business objects and let Rails do the rest. You`ll learn how to use the Action Pack framework to route incoming requests and render pages using easytowrite templates and components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, usercentric webpages using builtin Javascript and Ajax support. There are extensive chapters on testing, deployment, and scaling. You`ll see how easy it is to install Rails using your web server of choice (such as Apache or lighttpd) or using its own included web server. You`ll be writing applications that work with your favorite database (MySQL, Oracle, Postgres, and more) in no time at all. You`ll create a complete online store application in the extended tutorial section, so you`ll see how a full Rails application is developediteratively and rapidly. Rails strives to honor the Pragmatic Programmer`s DRY Principle by avoiding the extra work of configuration files and code annotations. You can develop in realtime: make a change, and watch it work immediately. Forget XML. Everything in Rails, from templates to control flow to business logic, is written in Ruby, the language of choice for programmers who like to get the job done well (and leave work on time for a change). Rails is the framework of choice for the new generation of Web 2.0 developers. Agile Web Development with Rails is the book for that generation, written by Dave Thomas (Pragmatic Programmer and author of Programming Ruby) and David Heinemeier Hansson, who created Rails.
