Waterline : Access populated value within a model

I am using sails.js to develop my first app. I have a waterline model as shown below.

//ModelA.js
module.exports = {
    attributes: {

        //more attributes

        userId: {
            model: 'user'
        },

        //more attributes
    }
};

I am using the model in one of my controllers as shown below.

  ModelA.find(options)
                .populate('userId')
                .exec(function (err, modelA) {
                    //some logic
                    //modelA.userId is undefined here
                    res.json(modelA); //userId is populated in the JSON output

                });

How do I get access to the populated value inside the model?

It's because find return an array of records. You have to use index to access an object and then userId of that object.

ModelA.find(options).populate('userId').exec(function (err, recordsOfModelA) {
    if(err) console.log(err);
    else console.log(recordsOfModelA[0].userId)
});

ModelA.find returns array of items. 

       ModelA.find(options)
        .populate('userId')
        .exec(function (err, results) {
            console.log(results[0].userId) //results is an array.
            //res.json(modelA); 

        });

Or you can use ModelA.findOne for a single record
