How to update a value inside mongodb with nodeJS? - node.js

Question

I'm trying to update a value inside mogoodb array but is the problem
database?
"TempChannels": [{
"user": "299481590445113345",
"channel": "794869948878159884",
"settings": []
}, {
"user": "583363766750806043",
"channel": "795004103998308352",
"settings": []
}],
The part of the code that should update the user:
Data.TempChannels[0].user = Target.id
Data.save().catch(er => console.log(er))
Also, no error appears when I run the code. and when i console the data it returns a user which has updated but it is not actually saved in mongodb!
code
Data.save().then(() => console.log(Data.TempChannels[0].user))
this is the whole data
{
"_id": {
"$oid": "5ff0cd1ee3d9fd2d40d82d23"
},
"TempChannels": [{
"user": "299481590445113345",
"channel": "795014692522295326",
"settings": []
}, {
"user": "583363766750806043",
"channel": "795015273060892753",
"settings": []
}],
"Guild": "704158258201624657",
"Stats": "true",
"ChannelID": "795014681664290826",
"ParentID": "795014680556994610",
"LogChannelID": "795014683601010709",
"TempControlChannelID": "795014682518749274",
"DefaultSettings": {
"limit": null,
"name": null,
"bitrate": null,
"copyperms": null
},
"__v": 2
}
I'm filtering the data by Guild

Answer 1

if you are using mongoose to connect MongoDB, the
Use markModified("updated field name")
Data.TempChannels[0].user = Target.id
Data.markModified('TempChannels');
Data.save().catch(er => console.log(er))

Answer 2

if you are using mongoose, there is a method that will allow to update the content of existing data
const res = await Person.replaceOne({ _id: 24601 }, { name: 'Jean Valjean' });
res.n; // Number of documents matched
res.nModified; // Number of documents modified

If you are using Mongoose, you can update the record by doing something similar to this:
SchemaName.update({Guild: 'Guild Value Here'}, {$set: { "TempChannels[0].user" : "%newvalue%"}})
.then((data) => {
console.log(data)
})
.catch(err => {
console.log.error(err);
});
You should replace schemaName with the name of your schema if you are using mongoose, and in case you are not using it, I think it would be better for you to start using it.
