node.js - How to use variable mongoose query? -

-

data schema

id: string,     item: {        possess: {           jewel: [number]      }

code

var temp = 1 db.collection.update({"id":"sample"},{"$set":{"item.possess.jewel.1":888})

how use variable temp in "item.possess.jewel.1" ?

"item.possess.jewel.temp" doesn't work

you have build $set object programmatically:

var temp = 1; var set = {$set: {}}; set.$set["item.possess.jewel." + temp] = 888; db.collection.update({"id":"sample"}, set);
