end

#update!(calculable = nil) ⇒ Object

Update both the eligibility and amount of the adjustment. Adjustments delegate updating of amount to their Originator when present, but only if locked is false. Adjustments that are locked will never change their amount.

order#update_adjustments passes self as the src, this is so calculations can be performed on the # current values. If we used source it would load the old record from db for the association
