Rails - Jul 2006 - Updating multiple children from one page

Hello,

I have a model called invoice and one called lineitem.  An invoice 
has_many lineitems, and an lineitem belongs to an invoice.  I have a 
model method that calculates the price of a lineitem, and one that 
calculates all lineitems in an invoice.  I want to have an edit page 
that lists all the invoices lineitems and their calculated prices, with 
a text field for a person to change the price that was calculated and 
save it into a different column, and have one submit button.  So I want 
to be able to edit all the child objects and save the changes to a new 
column, how could I implement this?

Thanks
