How to update document data in nested object in MongoDB? - node.js

Question

This is default schema model :-
const UserSettings = new Schema({
ID: { type: Number, required: true, exists: false, unique : true },
UserID : Number,
Account : {
Name : String,
Email : { type: String, required: "email id is required", exists: false, unique : true },
UserName : String,
isFacebook : {type : Boolean, default : false}
},
Notification : {
Trending : {
isEmail : {type : Boolean, default : true},
isPush : {type : Boolean, default : true},
Button : {
isDaily : {type : Boolean, default : false},
isWeekly : {type : Boolean, default : false},
isOff : {type : Boolean, default : false}
}
},
Recommanded : {
isEmail : {type : Boolean, default : true},
isPush : {type : Boolean, default : true},
Button : {
isDaily : {type : Boolean, default : false},
isWeekly : {type : Boolean, default : false},
isOff : {type : Boolean, default : false}
}
}
}
});
When I save values it will enter the default fields values in schema,
"Account" : {
"Email" : "ted#gmail.com",
"isFacebook" : true,
"Name" : "ted"
},
"Notification" : {
"Trending" : {
"Button" : {
"isDaily" : false,
"isWeekly" : false,
"isOff" : false
},
"isEmail" : true,
"isPush" : true
},
"Recommanded" : {
"Button" : {
"isDaily" : false,
"isWeekly" : false,
"isOff" : false
},
"isEmail" : true,
"isPush" : true
}
}
In update case I have to passed selected arguments like only need to Update
Account{
Email : "ted1#gmail.com"
},
Notification {
Trending {
isPush : false,
}
}
Then how would I used mongo update query?
I have tried this solutions to update value but it will removed existing value :-
return UserSettings.updateOne(
{$and: [{ UserID: args.UserID },{ Status : 1 }]},
{ $push : { "Account": args.Account }},
{
upsert: true,
returnNewDocument: true
},
);
and one more this :-
return UserSettings.updateOne(
{$and: [{ UserID: args.UserID },{ Status : 1 }]},
args,
{
upsert: true,
returnNewDocument: true
},
);

Try this:
let Account = args.Account
let condition = { $and: [ { UserID: args.UserID },{ Status : 1 }]}, { 'Account.Email': args.Account.Email }] }; // here check email in sub document
UserSettings.updateOne(condition, { $set: { Account: Account } }).exec((err, data) => {
if (err || data.nModified == 0) {
UserSettings.updateOne({ UserID: args.UserID }, { $push: { Account: Account } }).exec((err, data) => {
return {'message':'Updated successfully','data':data}; // Send proper response as per your need
});
}
else {
return {'message':'Failed'};// Send proper response as per your need
}
});
