java - Angularjs Unified view of two lists -
i'm working in app angularjs , java spring server application.
i got table takes data 2 lists containing objects different correlated:
object in list 1: {id, category_id, unit_cost, qty}
, coming db_table1.
object in list 2: {id, category_id, unit_cost, qty}
, coming db_table2.
the objects correlated category_id , differ in id , qty. there may cases when given category_id 1 of 2 objects exists.
i want show component rows follow
object_1.id, category_id, unit_cost, obj1.qty, obj1.qty*cost obj2.qty, obj2.qty*cost
(one row per category_id).
rows must include cases, so:
- when category there both obj1 , obj2
- when category there obj1 or obj2
which efficient method of build list ?
- on client side in component controller
- on server side, in spring service
