Rails - Jun 2006 - has_many validation

Hi all,
I''ve got a pretty standard has_many relationship here. Customer
has_many
items, and the association is being performed like so:

@customer.items << @item

My question regards the best way to perform validation when adding an 
item to a customer. Specifically, I need to make sure that a certain 
property of the @item matches that of the @customer. Does this type of 
validation take place in the Customer model? If so, how? Or should I 
create some wrapper around << in the Customer model, which would perform 
this validation and created the association? What''s the preferred 
method?

Thanks in advanced,
Doug
