Getting data from dynamic mongodb embedded object node.js

Question

Getting data from dynamic mongodb embedded object node.js

I have a mongoDB structure that looks like this:

values : { [
oneValue : {
     number: '20'
     unit: 'g'
}
differentValue : {
    number : '30'
    unit : 'g'
}
]}

I am using node js this is what I do:

doc.values.forEach(function(err, idx) {

var object = doc.values[idx];
}

And what ends up happening is I can get an object that looks like this:

object = oneValue : {
     number: '20'
     unit: 'g'
}

But node does not recognize it as a JSON because when I try to do JSON.parse(object) it doesn't know how to handle it.

I want to be able to get at the number field dynamically. So I don't want to say doc.values[idx].oneValue because this is a pretend case and in the real case oneValue could be one of 1000 different things. Does anyone know how I can access the 'number' field with this structure?

javascript
json
node.js
mongodb

Answer 1

figured it out...

after

var object = docs.values[idx]

do this:

var objAsJson = JSON.stringify(object);
JSON.parse(objAsJson, function(k, v) {
console.log(k + "  " + v);
});

That will print out all the data in the embedded object and you don't have to know the name.
