The "update" Method

We had the update method in models.js as following:

AnswerSchema.method("update", function (updates, callback) {
    Object.assign(this, updates, {updatedAt: new Date()});
    this.parent().save(callback);
});

Then we had this "change the specific question" solution in router.js as:

router.put('/:qID/answers/:aID', (req, res) => {
    req.answer.update(req.body, function(err, results) {
        if (err) return next(err);
        res.json(results);
    });

How should i connect / pair these two in my mindset?

In update method: function(updates, callback) matches with (req.body, function (err, results)?

Or it works in a different way?

Thanks!

Your thinking is correct! The update object is req.body and the callback function is the "function(err, results){...}" function.
