node.js - How to get and update a specific object inside an array with Mongoose? -

i'm having real trouble mongodb , mongoose queries. thing is, have menu schema:

var menuschema = new schema({     userid: string,     name: string,     meals: [{         day: number,         hour: number,         minute: number,         aliments: [{             name: string,             amount: number,         }],     }], }); 

so i'd know how specific meal or aliment , how update them throught _id value, automatically generated when add them.

thank much.

i working meals, not aliments. i'm doing meals:

menu.update({_id: request.params.menu_id, 'meals._id': request.params.meal_id}, {'meals.$.hour': request.body.hour)}, function(error, affected, raw) {     response.send(error); }); 

and aliments:

menu.update({_id: request.params.menu_id, 'meals.aliments._id': request.params.aliment_id}, {'meals.aliments.$': {name: request.body.name, amount: request.body.amount}}, function(error, affected, raw) {     response.send(error); }); 

edit: ok looked answer on other posts , found out solution.

looks $ positional operator not work multi-level arrays. actually, works 1-level arrays (that's why works meals doesn't aliments).

so guess solution splitting meals or aliments in documents , reference them mealid or alimentid.

i hope add multi-level positional operator soon. great.
