api - Rails sending parameters with array of id vs array of objects -

if have "bill" entity, might create bill instance via rest api assigning food ordered bill when go create new bill.

i.e. might make post request www.server.com/api/bills following parameters:

{     cost: 30.0,     foods: [23, 1, 14] } 

is better send array of ids or normal practice send array of objects? following:

{     cost: 30.0,     foods: [         {             id: 23,             name: "chicken parmesan",             price: 10.0         },         {             id: 1,             name: "scotch fillet steak",             price: 10.0         },         {             id: 14,             name: "baramundi",             price: 10.0         },     ] } 

yes, sending ids fine, though want check assigned id legit.

if don't have ids yet , want create objects (or update!) through association – sending nested array objects way go.

also, forgot mention! if sending just ids – means sending "special" rails field – food_ids, , rails magic. that's update of field, that's true rest.

i'd go food_ids if have no need in changing or creating foods, , i'd go foods_attributes (nested attributes) if i'd need to.
