def set_eligibility
  update_attribute_without_callbacks(:eligible,
                                     mandatory ||
                                     (amount != 0 && eligible_for_originator?))
end

#update!(src = 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. The new adjustment amount will be set by by the originator and is not automatically saved. This makes it save to use this method in an after_save hook for other models without causing an infinite recursion problem.

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
