Rails - Feb 2007 - Getting nicely formated error page for associated models.

I have a question regarding reporting of errors for models which
contain other models.

For example, if I have a User model which contains a Comments
collection, and I am not able to see any errors encountered when
validating the comments.

So if I do something like the following to append a new comment:

user = User.find(id)

comment = Comment.new(:comment => params[:comment_text],
                    :user_id => id)

user.comments << comment
user.save!

When I do this, with an empty :comment_text string, I get an exception
(coming from a validates_length_if associated with the Comment
model).

My question is, how can I get this to show on the form via
<%error_messages_for... %>, nicely formated instead of an application
exception error message?

At the moment I have a <%= error_messages_for :user %>, which results
in a nicely formated page showing any validation errors for User. But
not if an empty comment is added to the user''s comments collection.

Any help would be greatly appreciated.

Cheers,
Diego
