I stumbled across a set of screencast for those wanting to get started using the Monorail MVC framework, as well as ActiveRecord.
The first screencast deals with the basics of the Monorail Framework.
The second screencast deals with default views (a la master pages) and rescue views. It also deals with simple authentication patterns using Monorail filters. It also begins discussing databinding in Monorail.
The third screencast deals with advanced uses of databinding and ActiveRecord.
The fourth screencast is a consolidation of the first 3 screencasts, using validation and ActiveRecord, as wel, FormHelper methods, and the use of the Flash object.
The fifth and final screencast deals with some advanced topics, based on the previous screencasts, and some project that Castle has been working on.
