callback

I have a before filter than calculates a percentage that needs to include the object that is being updated. Is there a one liner in rails that takes care of this?

for example and this is totaly made up:

Object.find(:all, :include => :updated_object)

Currently I'm sending the object that is getting updated to the definition that calculates the percentage and that works but its making things messy.
