inheritance - sequelizejs, update attributes in inherit model -


i have model like:

---------------------- id | parent_id | sum 1  | nil       | 100 2  | 1         | 30 3  | 1         | 70 ---------------------

if instance 3 changed sum 60, instance 1 's sum change 90 too.

currently, use afterupdate hook change parent's sum, may cause lot of sql find parent's instance.

any other suggestion??
