Dynamic data in YAML fixtures

Right now I have this
lineitem_00001:
  id: 1
  orderrequest_id: 1
  product_id: 5
  quantity: 20
  total_price: <%= 20 * Product.find_by_id(5).price%>

Is it possible for the yaml parser to do something like this:?
  total_price: <%= quantity * Product.find_by_id(product_ID).price%>

On second hand, nevermind... I dont need to do this

Please supply what you _did_ do. Otherwise, you left an enticing hit
for a Google search on [dynamic yaml fixtures], with no conclusion.
