Answer 1

Checkout the WriteResult object:

http://docs.mongodb.org/manual/reference/method/db.collection.update/#writeresults-update

WriteResult result = collection.update({ "code": req.body.code },{$set:  req.body.updatedFields}, function(err, results) {
                    res.send({error: err, affected: results});
                    db.close();
                });

result should have something like:

WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })

If you want the updated results, do another query with the primary key.
