    An Introduction to Ruby and Rails This paper was originally presented at the Southwest Fox conference in Gilbert, Arizona in October, 2010. http://www.swfox.net An Introduction to Ruby and Rails Rick Borup Information Technology Associates 701 Devonshire Dr, Suite 127 Champaign, IL 61820 Voice: (217) 359-0918 Fax: (217) 398-0413 Email: [email protected] Ruby is a powerful, object-oriented, open-source language with a clean and easily understandable syntax. Originally released to the public in 1995, wide-spread interest in the Ruby language really began to take off in 2003 with the release of the Ruby on Rails® framework. Also known as "RoR" or simply "Rails", Ruby on Rails is an open-source Web framework that makes it possible to quickly and easily create data-based Web applications. Together, the Ruby language and the Ruby on Rails framework can become an exciting and powerful addition to any developer's toolbox. This session introduces both the Ruby language and the Rails framework, focusing on their installation and use on a Windows® platform with a perspective geared toward experienced Visual FoxPro® developers. © 2010 Rick Borup Page 1 of 64 An Introduction to Ruby and Rails Table of Contents Introduction............................................................................................................................................................ 4 Installing Ruby and Rails on Windows......................................................................................................... 4 Installing Instant Rails
