Ruby on Rails tutorial: learn web development with Rails (3rd ed.)

摘要

David Heinemeier Hansson released Ruby on Rails in 2004. Known as Rails, it is a model-view-controller (MVC) framework for developing web applications using standards such as JavaScript Object Notation (JSON) and Extensible Markup Language (XML) for data transfer; Hypertext Markup Language (HTML), cascading style sheets (CSS), and JavaScript for user interface; and software design principles such as convention over configuration, don't repeat yourself (DRY), and the active record pattern. It comes with an integrated web application development environment that includes scaffold generators for automatically generating a great deal of functionality for a website, a web server called WEBrick, and a build system called Rake. At the time of this writing, it is estimated that more than half a million websites are based on Ruby on Rails, which includes many high-profile companies, making it one of the most popular web development frameworks.
