How to add multiple scores to user in mongodb

I have built a quiz game where when a player finishes their score is submitted to mongodb as an object for e.g:
{
_id: "b7db3e12161567"
name: "james"
score: 5
}
Now what I want to do is to create multiple quizzes, not just one. I've created multiple quizzes which all have a unique name i.e quiz1, quiz2, quiz3 etc.
I want to use this quizId and give each player a score for the specific quiz they play instead of just one singular score. I was thinking something like:
{
_id: "b7db3e12161567"
name: "james",
quiz1: 5,
quiz2: 6
}
Here is my current code for the version which just the single score:
try {
const { _id, name, score, quizId } = req.body;
const users = await mongodb.getDb()
.db('database')
.collection('users')
.updateOne(
{ _id },
{ $set: { _id, name }, $max: { score } },
{ upsert: true }
);
res.json(users);
} catch(err) {
console.log(err);
throw new Error('Cannot add user score');
}
How would I implement what I suggested with mongo? And or would there be a better way to implement what I suggested?
Thanks

One option is to use an update with pipeline query like:
.updateOne(
{ _id, name }
[
{$set: {
quiz1: {$max: ["$quiz1", 3]},
quiz2: {$max: ["$quiz1", 7]}
}}
],
{ upsert: true }
)
Which works like this
You can create it dynamically of course with something like:
const setPart = {}
for (const quiz_name of Object.keys(quizes)) {
setPart[quiz_name] = `{$max: ["$${quiz_name}", ${quizes[quiz_name]}]}`
}
const users = await mongodb.getDb()
.db('database')
.collection('users')
.updateOne(
{ _id },
{ $set: setPart },
{ upsert: true }
);

Mongoose delete other objects after update

I'm having trouble with my update query on mongoose. I'm not sure why other objects get deleted after I update a specific object. the code works when I update but after that, the rest of the objects inside the array are getting deleted/removed. Literally, all of the remaining objects get deleted after the update request.
export const updateProduct = async (req,res) => {
const { id } = req.params;
try {
if(!mongoose.Types.ObjectId.isValid(id)) return res.status(404).json({ message: 'Invalid ID' });
await OwnerModels.findOneAndUpdate({'_id': id, store:{$elemMatch: {productname: req.body.store[0].productname }}},
{$set:
{
store:
{
productname: req.body.store[0].productname,
price: req.body.store[0].price,
quantity: req.body.store[0].quantity,
categoryfilter: req.body.store[0].categoryfilter,
description: req.body.store[0].description,
timestamp: req.body.store[0].timestamp
}
}
}, // list fields you like to change
{'new': true, 'safe': true, 'upsert': true});
} catch (error) {
res.status(404).json(error)
} }

I'm not sure why other objects get deleted after I update a specific object.
Because you are updating the whole object and it will replace the existing store array of object in the database,
You need to use arraFilters, and upsert is not effective in array of object updated, so i have commented,
await OwnerModels.findOneAndUpdate(
{
'_id': id,
store:{
$elemMatch: {
productname: req.body.store[0].productname
}
}
},
{
$set: {
store: {
"store.$[s].productname": req.body.store[0].productname,
"store.$[s].price": req.body.store[0].price,
"store.$[s].quantity": req.body.store[0].quantity,
"store.$[s].categoryfilter": req.body.store[0].categoryfilter,
"store.$[s].description": req.body.store[0].description,
"store.$[s].timestamp": req.body.store[0].timestamp
}
}
},
{
'arrayFilters': [
{ "s.productname": req.body.store[0].productname }
],
'new': true,
'safe': true,
// 'upsert': true
}
);

Mongodb, Delete one object from an array of objects using javascript

I am trying to remove one object from an array of my collection, which looks like this. It s a collection in Mongodb
Before deleting a specific object based on chartId, I need to check the userId and the name of the array. Then I need to delete the object.
I have written this code, but its not working. someone will tell me what exactly I am missing in this code.
delChartObj.updateOne(
{ 'userId': userId },
{ $pull: { "Color": { "chartId": req_chart_id } } },
{ safe: true, multi: true}, function (err, obj) {
if (err) { res.send.err }
res.status(200).send({ msg: "Deleted Sucessfully" });
});
In my case, userId = ADAM, array = "Color" and chartID = time
I am using mongoose for performing action
delChartObj is an object of model
const UserSchema = mongoose.Schema({
userId: { type: String, required: true, unique: true },
charts: { type: Object },
});

You should do findOneAndUpdate, the syntax will be something like:
Model.findOneAndUpdate(
< condition>,
{ $pull: { "Color.$.chartId": req_chart_id } } }, // The actual Query
{ new: true }
)

try this in pull
{ $pull: { "Chart.Color.$.chartId": req_chart_id } } },

Update or Upsert multiple document mongodb

I am working on a project using mongodb database, and I want to update or upsert multiple document.
So here is what I want to do:
if (you received an array of id )
{
create a verify condition which checks if there is a document for each id and respect the dateFin condition
}
else if (you received one id)
{
create a verify condition which checks if there is a document equal the id and respect the dateFin condition
}
then check if there is a document, then update it, else create it either you got an array or one id
if (Array.isArray(req.body.user) === true)
verify = {
idUser: { $in: req.body.user.map(id => { return ObjectId(id) }) },
dateFin: { $gt: moment().utc(1).format('YYYY-MM-DD HH:MM:SS') }
}
else verify =
{
idUser: ObjectId(req.body.user),
dateFin: { $gt: moment().utc(1).format('YYYY-MM-DD HH:MM:SS') }
}
db.collection("paiement").updateMany(verify,
{
$set: {
dateFin: moment(req.body.date).format('YYYY-MM-DD HH:MM:SS'),
paiementType: "offre",
abonnement: req.body.abonnement,
dateInsert: moment().utc(1).format('YYYY-MM-DD HH:MM:SS'),
},
},
{ upsert: true },
(err, document) => {
if (err) return res.status(400).json(err);
console.log(err);
console.log(document.result);
})
}
but it works with one id, and not with multiple ids, Thank you if there is any one can help me.

delete object from document array in mongodb collection using mongoose

I try to remove an element from an array attribute of my object.
This is my schema :
const userSchema = new mongoose.Schema({
userID: {
type: Number
},
name: {
type: String
},
names: [
{
text: { type: String, required: true },
order: {
type: Number,
required: true
}
}
]
});
this is my mongoose function :
User.findOne({ userID: Number(req.params.id) })
.then((user) => {
user.names.remove({text: "john", order: 3});
recipe.save(() => {
res.json(recipe);
});
})
I don't understand why it's not good :/

As per documentation of mongoose remove method remove operation is only executed when a callback is passed. To force execution without a callback, you must first call remove() and then execute it by using the exec() method.
Since you are trying to delete from array of objects then better would be to use pull operator. You don't have to do find and remove, you can simply use update method.
As per documentation of $pull operator you can either specify a value or a condition
i.e.
{ $pull: { <field1>: <value|condition>, <field2>: <value|condition>, ... } }
In your scenario you need to either specify complete value of one or more names item object or an condition that matches one or more names item
Add the condition where you match id of names item or if you don't know that then you can use elemMatch to match on few fields i.e.
Use following pull condition to solve the issue:
User.update(
{ _id: Number(req.params.id) },
{ $pull: { 'names': { $elemMatch: { 'text': "john", 'order': 3 }} } },
(error, success) => {
if (error) console.log(error);
console.log(success);
}
);

To Remove Element from array in document please follow as below
User.update(
{
userID: Number(req.params.id),
},
{
$pull: { names: { $elemMatch: { text: "john", order: 3 } } }
},
{
multi: false
}
).lean().then((Status) => {
console.log("Status-->", Status);
res.json('Removed Successfully');
})
Refer $pull operator at link
