Multiple Record Form and Controller to update Multiple Model

I couldn’t find any examples of how to create a multiple record form and
controller for updating multiple models from one form. Once I figured
it
out I posted it at:
http://thebitt.blogspot.com/2006/01/multiple-record-forms-for-ruby-on.html

It code creates an account with a user. It collects account name and
user
information and then updates both account and user models.

I still don’t know how to grab the validation error messages so I can
consolidate them into one message for the user. If anyone knows how,
I’d
love to know.

thanks
