Ruby on Rails Training Overview

This Ruby on Rails training course teaches attendees how to build web applications using the powerful Rails framework (see http://www.rubyonrails.com) based on the highly dynamic, pure OO language Ruby. Rails uses the principles of DRY (Don't Repeat Yourself) and "convention over configuration" to help build robust, scalable applications extremely quickly.

We also offer an Advanced Ruby on Rails course.

Ruby on Rails Training Prerequisites

All Ruby on Rails training attendees should have some experience with server-side web development. Programming experience in an object-oriented language would also be helpful.

Hands-on/Lecture Ratio

This course is a fast-paced, hands-on workshop, with the bulk of class time spent developing Ruby on Rails applications in consultation with a seasoned instructor.

Ruby on Rails Training Materials

All students receive copies of Pragmatic Programmers' Agile Web Development with Rails and Manning's Ruby For Rails, as well as related courseware.

Software Needed on Each Student PC

The Ruby interpreter version 1.8.6 or later.
The Rails framework 2.0.0 or later.
SQLite3 and MySQL databases (http://dev.mysql.com) works immediately with Rails, but many others have supported adapters (DB2, Oracle, and Postgres among them).
A plain text editor, preferably one that understands the syntax of Ruby and Rails.

Note: We would be delighted to customize the platform of this class to match what you are running in production.
