Get Mongo field value as Variable?

Question

Gentlemen, I’m using this code on the Meteor:

var teste = Orders.findOne({name : 'Day'}).day;

To Get the day value on this record:

{_id: "HzoGFKRmYzmH8Yx6A", name: "Day", day: "Jan 27th 18"}

It gives an error, but redeems the amount I want, is there any way to redeem this value without this error?

Answer 1

Bro, this has worked:

Orders.find({name : 'Day'}). fetch(). foreach(Function(day){ var day = day.day; console.log(day);

Answer 2

Man... it works like a charm for me. But by way of syntax, put the name of the field of your collection between single quotes and the value to be searched in double quotes, like this:

let teste = Orders.findOne({'name': "Day"}).day;
console.log(teste);

Answer 3

The findOne is an asynchronous instruction, so the correct way to access the result of the query is in callback, thus:

Orders.findOne({name : 'Day'}, function(err, day){
    if (!err){
        let teste = day; // aqui a variavel teste recebe o retorno da consulta
    }
});
