Ruby Rails _without_ ActiveRecord

Question

I am looking for any pointers on how to write a rails web application without ActiveRecord.

A document or an example of a (not too complicated) web application using storage databases other than a relational database would be greatly appreciated.

It is not clear what needs to be implemented in the model classes for the rails application to work without an ActiveRecord layer.

Thank,
