Ruby on Rails on Oracle: A Simple Tutorial
in Ruby added by admin, on 29/11/2007 database intermediate oracle ruby on rails
This article is not intended to be a booster piece for Rails nor is it an expose. It's simply an introduction to the technology. It contains both praise and criticism. At times the criticism might appear a bit heavy handed (especially to Rails enthusiasts), but don't be fooled. Using any Web application framework is going to be tricky, whether it's J2EE, ASP.NET, or PHP. In the long run, you can be a lot more productive with Rails than you can be with many other Web application development platforms, but it takes time to learn the ropes.

in Ruby added by admin, on 18/11/2007 beginner tutorials framework ruby on rails

A popular text editor used by many Rails programmers is TextMate, a Cocoa application. And all members of the Rails core development team work with Macs.

Rolling with Ruby on Rails, Part 2
in Ruby added by admin, on 21/10/2007 beginner tutorials oo programming ruby on rails
In Rolling with Ruby on Rails, I barely scratched the surface of what you can do with Ruby on Rails. I didn't talk about data validation or database transactions, and I did not mention callbacks, unit testing, or caching. There was hardly a mention of the many helpers that Rails includes to make your life easier. I can't really do justice to all of these topics in the space of this article, but I will go into details on some of them and present a brief overview of the rest, with links to more detailed information.

Rolling with Ruby on Rails
in Ruby added by admin, on 21/10/2007 beginner tutorials ruby on rails setup
Maybe you've heard about Ruby on Rails, the super productive new way to develop web applications, and you'd like to give it a try, but you don't know anything about Ruby or Rails. This article steps through the development of a web application using Rails. It won't teach you how to program in Ruby, but if you already know another object-oriented programming language, you should have no problem following along (and at the end you can find links on learning Ruby).
Let's answer a couple of burning questions before rolling up our sleeves to build a web application!
