I'm running this code on node.js
var mongoose = require('mongoose');
mongoose.model('participant',new mongoose.Schema({},{ collection : 'forumParticipant' }));
var Participant = mongoose.model('participant');
mongoose.connect('******');
Participant.find({entity_id: 0}, function (err, docs) {
console.log(docs[0]);
console.log(docs[0].entity_id)
});
1) The first console.log return the full document
2) The second console.log return undefinied
I don't understand why.
I need to perform something like
var participants = docs.map(function(d){return d.user_id})
How can I achieve that? What am I missing ?
I suspect the value you are trying to get is not in your Schema
but is stored in your database.
You have two solutions from there. You can either add entity_id
to your Schema
and Mongo will be able to bind it to the Document
object you receive. This is the recommended way.
Or you can bypass mongoose Schema
and access the raw document stored in the database with docs[0]._doc.entity_id
. I don't recommend this solution unless you know what you're doing.
