I need to update different fields of a nested array in Mongoose. Sometimes I will send runId and runStatus, some other times siteFetched and some other times siteInfo.
I have tried with the following code but the $set operator replaces the old fields.
The model:
campaignId: { type: String },
keywords: [{
keyword: { type: String },
serp: {
runId: { type: String },
runStatus: { type: String },
siteFetched: { type: Boolean },
sitesInfo: [{
title: { type: String },
url: { type: String },
description: { type: String },
}],
},
},
],
Here is the code to update
const campaign = await Campaign.findOneAndUpdate(
{ _id: campaignId, "keywords.keyword": keyword },
{
$set: { "keywords.$.apifySerp": {...serp }},
}
);
the value for serp varies like
const serp = {
runId: '1kLgbnvpADsDJyP1x',
runStatus: 'READY'
}
and
const serp = {
siteFetched: true
}
Here is the code that solved my problem.
const serp = {
siteFetched: true,
};
let update = Object.keys(serp).reduce((acc, cur) => {
acc[`keywords.$.apifySerp.${cur}`] = serp[cur];
return acc;
}, {});

I am using findOneAndUpdate, where I want
to return updated document
i dont want to return the entire document but only the following:
one object out of an array + a virtual property in the document.
const notifications = {
to:
messages: [
{_id: "23452", title:"hello"}, {_id: "23452", title:"bye"}
]
...
}
so for example I would want to only return the object {_id: "23452", title:"bye"} AND unreadCount virtual field prop.
my code works so far as I am returning updated document and only the message I want, but I dont know how to return also the unreadCount prop.
schema:
const notificationSchema = new mongoose.Schema({
to: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
messages: [{
title: {
type: String,
required: true
},
isRead: {
type: Boolean,
default: false
},
createdAt: {
type: Date,
default: new Date()
}
}, ]
},
{timestamps: true, toObject: {virtuals: true}
});
notificationSchema.virtual('unreadCount').get(function() {
... return count;...
})
updateRead: async (userId, id) => {
const notification = await Notification.findOneAndUpdate({to: userId, 'messages._id': id}, {
$set: { "messages.$.isRead": true} },
{ select: {
messages: {
$elemMatch: {_id: id}
}
}, new: true});
}
I am creating express server for the project and I used the mongodb for the database. I am getting error,
Error validating $lookup value. err=$lookup against an expression value is not allowed in this atlas tier.
movies schema,
const mongoose = require("mongoose");
const MovieSchema = new mongoose.Schema(
{
title: { type: String, required: true, unique: true },
desc: { type: String },
img: { type: String },
imgTitle: { type: String },
imgSm: { type: String },
trailer: { type: String },
video: { type: String },
year: { type: String },
limit: { type: Number },
genre: { type: String },
isSeries: { type: Boolean, default: false },
},
{ timestamps: true }
);
module.exports = mongoose.model("movies", MovieSchema);
My lists schema,
const ListSchema = new mongoose.Schema(
{
title: { type: String, required: true, unique: true },
type: { type: String },
genre: { type: String },
content: [
{ type: mongoose.Schema.Types.ObjectId, required: false, ref: "movies" },
],
},
{ timestamps: true }
);
lists schema has a content property and it's contains the ids of the movies.so I need to have get all movies in the list with sample size 4,so I write aggregation for the list schema for populating movies object in content property in list schema. So where is the bug in my code ?I hope your help!
so I coded it as,
const list = await List.aggregate([
{ $sample: { size: 4 } },
{
$lookup: {
from: "$movies",
foreignField: "_id",
localField: "content",
as: "content",
},
},
]);
}
res.status(200).json(list);
I have a field achivment with an array of objects. I need to update the field currentPoints in one object that I will find by field name in the array.
Code model of mongoose:
const achive = new Schema(
{
achiveId: ObjectId,
name: { type: String, required: true },
finishedPoints: { type: Number, required: true },
currentPoints: {
type: Number,
default: 0,
set: function (v) {
if (v >= this.finishedPoints) this.isFinished = true;
return v;
}
},
isFinished: { type: Boolean, default: false }
},
{ _id: false }
);
const achivesSchema = new Schema({
userId: ObjectId,
achivement: [achive]
});
Code query:
export async function progressAchive(req, res) {
const value = 3;
try {
const test = await Achives.updateOne(
{
userId: req.user._id,
achivement: { $elemMatch: { name: req.params.nameAchive } }
},
{ $set: { achivement: { currentPoints: value } } },
{ new: true }
);
res.json(test);
} catch (e) {
console.log(e);
}
}
Instead of updating, it removes all objects from the array and leaves them one object with the currentPoint field. How can I update this like I want?
You should use the following for update
const test = await Achives.updateOne(
{
userId: req.user._id,
},
{
$set:{"achivement.$[el].currentPoints": value}
},
{
arrayFilters:[{
"el.name": req.params.nameAchive
}],
new: true
}
);
i am strugling with a query that i don't know how to perform... I have two collections,
Tarifas Collection
tarifaConfig = new Schema({
producto: { type: String },
titulo: { type: String },
bloqueo: { type: Boolean },
margen: { type: Number },
precioVenta: { type: Number },
precioVentaIva: { type: Number },
})
const tarifaSchema = new Schema({
codigo: { type: String },
titulo: { type: String },
margen: { type: Number },
estado: { type: Boolean },
bloqueo: { type: Boolean },
configs: [tarifaConfig]
})
Producto Collection
const productosSchema = new Schema({
ref: { type: String },
nombre: { type: String },
precioCompra: { type: Number },
precioCompraIva: { type: Number },
precioVenta: { type: Number },
precioVentaIva: { type: Number },
iva: { type: Number },
})
Now i am using an Aggregation method to retrieve both collection in a response
productosModel.aggregate([
{
$match: { _id: ObjectId(req.params.id) }
},
{
$lookup: {
from: "tarifas",
as: "tarifas",
pipeline: []
}
}
]).then((producto) => {
res.json(producto);
})
This is working and gives me both collections in the response... but..
In tarifa's collection i have a propertie called 'configs' that is an array with lot of sub collections... this sub collections are a config of each product that i have,
So what i need to do is, retrieve all tarifas that has a configs for the product, and if the configs does not contain retrieve the tarifa with a empty array.
Expected result
{
ref: 'rbe34',
nombre: 'bike',
precioCompra: 10,
precioCompraIva: 12.1,
precioVenta: "",
precioVentaIva: "",
iva: 21,
tarifas:[
{
codigo: 'NOR',
titulo: 'Normal tarifa',
margen: 33,
estado: true,
bloqueo: true,
configs: [], ///HERE I NEED A EMPTY ARRAY IF THERE IS NOT ANY CONFIG THAT MATCH WITH THE PRODUCT ID,
}
]
}
i tried to add $match in my aggregation pipeline.
productosModel.aggregate([
{
$match: { _id: ObjectId(req.params.id) }
},
{
$lookup: {
from: "tarifas",
as: "tarifas",
pipeline: [
{ $match: { 'configs.producto': req.params.id } }
]
}
}
])
But if there is not any config that match the product it doesn't retrieve the rest of Tarifa's collection
It seems you are trying to $filter the array after you retrieve it.
This pipeline will return only the configs for which the producto field from the config matches the ref field from the product.
[
{
$match: { _id: ObjectId(req.params.id) }
},
{
$lookup: {
from: "tarifas",
as: "tarifas",
pipeline: [
{
$addFields: {
"tarifas.configs":{ $filter:{
input: "$tarifas.configs",
cond: {$eq:["$$this.producto","$ref"]}
} }
}
}
]
}
},
]
Change the fields in the $eq array to the ones you need to match.
This question already has answers here:
Node.js Mongoose.js string to ObjectId function
(9 answers)
Closed 4 years ago.
I have an array of ids which is launchIds.
I'm trying to push it on a model field trips with
$addToSet: { trips: { $each: launchIds }. This gives me an error: Cast to [ObjectId] failed for value \"[\"1\",\"2\",\"3\"]\...
if I try to map through launchIds and convert to Mongoose.Shema.Types.ObjectId I get in the database trips: [null,null,null]
lauchIds = ['1','2','3']
async bookTrips({ launchIds }) {
let userId = "5bf7f7b3817119363da48403";
const mongoIds = launchIds.map(l => Mongoose.Schema.Types.ObjectId(l));
return this.store.User.findByIdAndUpdate(
{ _id: userId },
{
$addToSet: { trips: { $each: mongoIds } }
},
{ new: true }
);
}
Here's my model Schema:
const UserSchema = new Mongoose.Schema(
{
email: {
type: String,
required: true
},
token: String,
trips: [
{
type: Mongoose.Schema.Types.ObjectId,
ref: "trip"
}
]
},
{ timestamps: true }
);
I'm passing ids via grapql playground. Here's my mutation:
bookTrips: async (_, { launchIds }, { dataSources }) => {
console.log(launchIds);
// logs ['1','2','3']
console.log(typeof launchIds);
//Object
const results = await dataSources.userAPI.bookTrips({ launchIds });
console.log(results);
return { message: "hello" };
}
To convert a string or a number into mongo object use Mongoose.Types.ObjectId,
const mongoIds = launchIds.map(l => Mongoose.Types.ObjectId(l));
I was getting back an array of strings where this should be numbers
The solution:
My model (same as above):
const UserSchema = new Mongoose.Schema(
{
email: {
type: String,
required: true
},
token: String,
trips: [
{
type: Mongoose.Schema.Types.ObjectId,
ref: "trip"
}
]
},
{ timestamps: true }
);
crud API:
async bookTrips({ launchIds }) {
let userId = "5bf7f7b3817119363da48403";
const idsToNums = launchIds.map(Number);
const mongoIds = idsToNums.map(l => Mongoose.Types.ObjectId(l));
return this.store.User.findByIdAndUpdate(
{ _id: userId },
{
$push: { trips: { $each: mongoIds } }
},
{ new: true }
);
}
Notice the Mongoose.Schema.Types.ObjectId on model and Mongoose.Types.ObjectId on api. If I remove Schema from model or add Schema to api I'm getting an error. Not sure why, but the above example works. I hope someone will find this helpful or suggests a better solution.
