i am trying to update or remove a subdocument from a parent document using mongoose.
My code:
editSubscription(req, res) {
const token = req.headers.authorization;
jwt.verify(token, req.app.get('yourSecretKey'), function (err, payload) {
userModel.update({ _id: payload.user._id, "subscriptions._id": req.params.id }, { "$set": { "subscriptions.$": req.body } }, function (err, obj) {
console.log(obj)
})
})
}
The output of the console.log is
{ n: 0, nModified: 0, ok: 1 }
How should i do this? i know if its modified the nModified returns a 1. I can't find any docs on how to approach this or solve it and all the solutions here on stackoverflow i already tried, nothing is working.
A sample of a document in my collection:
id: '5db990daa05aa90de0c8b86b',
user:
{ role: 'User',
subscriptions: [
{ active: true,
_id: '5dbad05aaf232e2bdc033339',
name: 'Basic Fit',
price: 20,
paymentDate: '07-11-2020',
created: '2019-10-31T12:15:22.360Z',
updated: '2019-10-31T12:15:22.360Z' },
{ active: true,
_id: '5dbad2568bf56255a0f39bc7',
name: 'Netflix',
price: 10,
paymentDate: '07-11-2019',
created: '2019-10-31T12:23:50.141Z',
updated: '2019-10-31T12:23:50.141Z' } ]
],
_id: '5db990daa05aa90de0c8b86b',
fullname: 'Test naam',
email: 'test1#mail.com',
password:
'$2a$10$VzBnIcVraIRdmzy6rPHOX.7gGOXToTBNISLEfi429OfpRx02FxCaO',
birthDate: '02-12-1988',
created: '2019-10-30T13:32:10.276Z',
updated: '2019-10-30T13:32:10.276Z',
__v: 0 },
payload.user._id == the verified logged in user ID
req.params.id is supposed to be the subscriptionId im trying to edit
Try this:
editSubscription(req, res) {
const token = req.headers.authorization;
jwt.verify(token, req.app.get('yourSecretKey'), function (err, payload) {
userModel.update({ _id: ObjectId(payload.user._id), "subscriptions._id": ObjectId(req.params.id) }, { "$set": { "subscriptions.$": req.body } }, function (err, obj) {
console.log(obj)
})
})
}
I tried and im getting a 500 error response back..
When i remove the 'req.params.id' and i do it like this:
userModel.updateOne({ _id: payload.user._id }, { "$set": { "subscriptions.0.price":
req.body.price} }).then(user => {
console.log(user)
}).catch(err => {
console.log(err)
})
Then it works but since i have multiple items in an array i do not want to update only the first one..
I tried using a filter in the $set operator but im getting errors all over the place..

how I update my array data in nested array in node js and mongo db. when i was try to save data then massage was print but data not saved in mongo db, please check schema and back end code explain which sentence to create a problem.
// schema
mainmenu: [
{
arrname: String,
submenuarray: [
{
dishname1: {
type: String,
},
prize1: {
type: Number,
},
dishcategory1: {
type: String,

},
],
},
];
// back End
app.patch('/addsubmenu/:id/:mainid', async (req, res) => {
const mainid = req.params.mainid;
console.log(mainid);
const id = req.params.id;
console.log(id);
getschema
.findByIdAndUpdate(
{ _id: mainid, 'submenuarray._id': id },
{
$push: {
submenuarray: {
dishname1: req.body.dishname1,
prize1: req.body.prize1,
dishcategory1: req.body.dishcategory1,

},
}
)
.then((data) => {
console.log(data);
res.status(201).json(data);
})
.catch((err) => {
console.log(err);
});
});
The findByIdAndUpdate accept the id as first parameter, try to use findOneAndUpdate.
Also, set the flag { new: true} to return the updated object:
getschema
.findOneAndUpdate(
{ _id: mainid, 'submenuarray._id': id },
{
$push: {
submenuarray: {
dishname1: req.body.dishname1,
prize1: req.body.prize1,
dishcategory1: req.body.dishcategory1,
},
},
},
{ new: true }
)
.then((data) => {
console.log(data);
res.status(201).json(data);
})
.catch((err) => {
console.log(err);
});
I was trying to $pull an object inside my cart collections. but after I make a request and sent a specific _id it gives me a different person.
this was the _id I sent from my client side.
{ id: '62a849957410ef5849491b1b' } /// from console.log(req.params);
here's my mongoose query.
export const deleteItem = (req,res) => {
const { id } = req.params;
console.log(id);
try {
if(!mongoose.Types.ObjectId.isValid(id)) return res.status(404).json({ message: 'ID not found' });
ClientModels.findOneAndUpdate(id, {
$pull: {
cart: {
product_identifier: req.body.cart[0].product_identifier
}
}
},{
new: true
}).then(val => console.log(val)).catch(temp => console.log(temp));
} catch (error) {
res.status(404).json(error);
}
}
after the request here's the callback.
{
_id: new ObjectId("62a77ab16210bf1afd8bd0a9"),
fullname: 'Gino Dela Vega',
address: '008 Estrella.st santo cristo',
email: 'gamexgaming1997#gmail.com',
google_id: 'none',
birthday: '1997-12-30',
number: 9922325221,
gender: 'Male',
username: 'ginopogi',
password: '$2b$12$YCc1jclth.ux4diwpt7EXeqYyLOG0bEaF.wvl9hkqNVptY.1Jsuvi',
cart: [],
wishlist: [],
toBeDeliver: [],
Delivered: [],
__v: 0
}
as you guys can see after sending a specific _id to find a user...the callback gives me a different user reason that I can't pull the specific object inside cart. (the object I was trying to pull is on another user)
Probably because findOneAndUpdate expect a filter as first parameter, try to switch to findByIdAndUpdate if you want to filter by a specific _id:
export const deleteItem = (req, res) => {
...
ClientModels.findByIdAndUpdate(
id,
{
$pull: {
cart: {
product_identifier: req.body.cart[0].product_identifier,
},
},
},
{
new: true,
}
)
.then((val) => console.log(val))
.catch((temp) => console.log(temp));
} catch (error) {
res.status(404).json(error);
}
};
I have a collection with name User in my mongodb for the example you can see in below a sample of saved user
{
_id: new ObjectId("61488f3892099143ca2b2bbc"),
name: 'test',
orders: [],
products: [
{
name: 'as',
image: '049fcd8d-f954-4aef-bd77-757af881f7c5.jpeg',
_id: new ObjectId("61531666ad63a47ed692c90b")
},
]
}
I have function with node.js that has responsible to add new product to selected user
async function addProduct(req, res, next) {
await User.findOneAndUpdate(
{ _id: req.params.userId },
{
$addToSet: {
products: {
...req.body,
image: req.file.filename,
},
},
}
);
return res.status(200).send();
}
but I want to send only new added product as response
please help me to solve this problem.
I recommend you to use the $push operator (doc):
{ $push: { <field1>: <value1>, ... } }
Using it with your example:
(async () => {
await User.findByIdAndUpdate(
'6153769ce997d65baf860cc7',
{
$push: {
products: {
name: 'as2',
image: '589fcd8d-f954-4aef-bd77-757af881f7c5.jpeg'
}
}
}
);
})();
I need to remove the user's id from all objects in the collection except the one that was passed, in my example it is value: 'Тата', tell me how to make such a request?
console.log(result)
[
{
_id: 5fa702b2f18e5723b4c00d9f,
value: 'Тата',
vote: { '36e7da32-f818-4771-bb5e-1807b2954b5f': [Array] },
date: 2020-11-07T20:25:22.611Z,
__v: 0
}
]
console.log(req.body)
{ value: 'Тата', habalkaId: '36e7da32-f818-4771-bb5e-1807b2954b5f' }
console.log(req.user._id)
5f63a251f17f1f38bc92bdab
that's all I could do, just find
router.post('/', passport.authenticate('jwt', {session: false}), (req, res) => {
FirstName.find({value: req.body.value})
.then(result => {
if (result.length) {
console.log(result)
console.log(req.body)
console.log(req.user._id)
FirstName.find({value: {$ne: 'Слоник'}}, function (err, arr) {
arr.map(e => {
if (e.vote[req.body.habalkaId].length) {
if(e.vote[req.body.habalkaId].includes(String(req.user._id))){
console.log(e.vote[req.body.habalkaId])
}
}
})
})
} else {
new FirstName({
value: req.body.value,
vote: {[req.body.habalkaId]: [String(req.user._id)]}
}).save();
}
})
// res.json({res: req.body})
})
FirstName.js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
// Create Schema
const FirstNameSchema = new Schema({
value: {
type: String
},
vote: {
type: Object
},
date: {
type: Date,
default: Date.now
}
});
module.exports = FirstName = mongoose.model('firstname', FirstNameSchema);
If I've understand well, you want something like this:
db.collection.update({
"value": {
"$ne": "tata"
}
},
{
"$pull": {
"vote.array_name": "id_value"
}
},
{
multi: true
})
First of all, find all document that not match the value with the given one. Then, for each document found, delete the object from the array, using $pull where the id given matches.
Example here
Please check the payground and check if I've used the correct schema and it shows the expected output.
I'm trying to use a projection parameter on findOne() to extract a single field from a document (stats) but it just seems to return the whole document. I'm using version "mongodb": "^3.4.1" in Node.js
This is the document structure
{ _id: 5e563015fa9a1a0134cac3cb,
username: 'user1',
password: '1234',
email: 'user#email.com',
stats:
{ totalViewed: 122,
totalUnique: 4,
tknow: 80,
tdknow: 42,
setCnt: 78 },
progress:
[ { cardId: 1001, knowCnt: 3, dknowCnt: 4 },
{ cardId: 1016, knowCnt: 0, dknowCnt: 0 } ] }
This is the code:
var findOneDoc = function() {
db.collection("testusers").findOne(
{ username: "user1" },
{ stats: 1 }, //field to return
function(err, result) {
if (err) {
console.log("Error: ", err);
}
console.log("Success: ", result);
}
);
};
findOneDoc();
I also tried:{$project: {stats: 1}}, to no avail
Thanks
Based on the documentation the .findOne() method takes options as a second parameter and it is recommended to use projection to define fields:
db.collection("testusers").findOne(
{ username: "user1" },
{ projection: { stats: 1 } },
function(err, result) { ... }
);
with findOne operations, the second parameter passed is an options parameter, so you should pass in your projects within the options parameter, like this:
query = { username: "user1" };
options = { projection: { stats: 1 }};
db.collection("testusers").findOne(query, options)
you can do it like mick said, with findOne
await db.collection("testusers").findOne(
{ username: "user1" },
{ projection: { stats: 1 } },
function(err, result) { ... }
);
or you can do it with find, like that
await db.collection("testusers")
.find({ username: "user1" })
.limit(1)
.project(["stats"])
.toArray()
you can add fields to the array project for more fields
findOne returns a document. use find() …..
