mongoose updating a field in a MongoDB not working - mongodb

Question

I have this code
var UserSchema = new Schema({
Username: {type: String, index: true},
Password: String,
Email: String,
Points: {type: Number, default: 0}
});
[...]
var User = db.model('User');
/*
* Function to save the points in the user's account
*/
function savePoints(name, points){
if(name != "unregistered user"){
User.find({Username: name}, function(err, users){
var oldPoints = users[0].Points;
var newPoints = oldPoints + points;
User.update({name: name}, { $inc: {Points: newPoints}}, function(err){
if(err){
console.log("some error happened when update");
}
else{
console.log("update successfull! with name = " + name);
User.find({Username: name}, function(err, users) {
console.log("updated : " + users[0].Points);
});
}
});
});
}
}
savePoints("Masiar", 666);
I would like to update my user (by finding it with its name) by
updating his/her points. I'm sure oldPoints and points contain a
value, but still my user keep being at zero points. The console prints
"update successful".
What am I doing wrong? Sorry for the stupid / noob question.

Answer 1

It seems you are doing a few unstandard things:
Use findOne instead of find if you want to load just one user
Calling Model.update should be done to update records that you have not loaded
$inc is adding oldPoints, so the new value will be 2*oldPoints + newPoints
You are using name as the conditional query instead of Username
I would rewrite the code into something like this:
User.findOne({Username: name}, function(err, user){
if (err) { return next(err); }
user.Points += points;
user.save(function(err) {
if (err) { return next(err); }
});
});

follow my code guy
User.update({ username: "faibaa" },
{ $inc: { point: 200000 } }, function(err,data){
return res.send(data);
});
