I attended a 2 day course on RoR during the Good Friday weekend. It was a beginners course.
RoR has a lot of “magic” moments when you just click a few buttons and ‘viola’, it spews out a shiny new web application for you. Nothing hard core though as the “scaffolding” as it is called is only good for the very basic CRUD web apps.
On the other hand, I found very little information available on the net that could explain what was happening under the hoods. It is possible that I did not look in the right places, though.
I am now practicing the concepts by creating a simple effort tracking web application in my free time.
