Easiest way to copy/clone a mongoose document instance?

Question

My approach would be to get the document instance, and create a new one from the instance fields. I am sure there is a better way to do it.

For simply clone use this :

Context.findOne({
    _id: context._id
})
    .then(function(c) {
        c._id = undefined;
        c.name = context.name;
        c.address = context.address;
        c.created = Date.now();
        return Context.create(c.toObject());
    }).then(function(c) {
        return res.json({
            success: true,
            context: context
        });
    }).catch(function(err) {
        next(err, req, res);
    });
