i'm new to mongoose, I want to update my city_name, my schema structure looks like
const addressSchema = new mongoose.schema({
address:{
door_no:{type:number},
other_details:{
street_name:{ type: string},
city:{
city_name:{type:string},
pincode:{type:string},
}
}
}
})
sample db data :
{
"_id": "63dw8sdhs8ad0s",
"address": {
"door_no": 43,
"other_details": {
"street": "sdsadada",
"city": {
"city_name": "dfaef"
}
}
}
}
now i want to update the city_name i tried this query
addressModel.findByIdAndUpdate({_id:id},{$set:{'address.other_details.city.city_name':'44xd3xc'}})
but it doesn't update for me.
check that you passing id crctly or not

I have a find() query that when executed, I can see the json with the nested schemas that I want to see except for the 'artista' attribute only displays the id, instead of the properties I want. See below:
{
"total": 1,
"ordenes": [
{
"artpieces": [
{
"_id": "60c1388f30316c02b9f6351f",
"artista": "60c055736c7ca511055a0e1a",
"nombre": "LILIES"
},
{
"_id": "60c12fca30316c02b9f63519",
"nombre": "GERNICA",
"artista": "60c136bf30316c02b9f6351b"
}
],
"_id": "60c414f9ea108a14ef75a9fb",
"precio": 3000,
"usuario": {
"_id": "609c0068e67e68",
"nombre": "Arturo Filio"
}
}
]
}
The query I use to get the json above:
const [total, ordenes] = await Promise.all([
Orden.countDocuments(),
Orden.find()
.populate("usuario", "nombre")
.populate("artpieces", ["nombre","artista","nombre"])
]);
res.json({
total,
ordenes
});
It's an order schema that has artpieces. Each artpiece (I called it 'producto'), has a name a genre, an author/artist and the user which the order belongs to.
my Schema for the orden.js:
const { Schema, model } = require('mongoose');
const OrdenSchema = Schema({
artpieces: [
{
type: Schema.Types.ObjectId,
required: true,
ref: 'Producto'
}
],
estado: {
type: Boolean,
default: true,
required: true
},
usuario: {
type: Schema.Types.ObjectId,
ref: 'Usuario',
required: true
},
precio: {
type: Number,
required: true
}
})
OrdenSchema.methods.toJSON = function () {
const { __v, estado, ...data} = this.toObject();
return data;
}
module.exports = model('Orden', OrdenSchema);
Last thing I want to mention, I know for a fact that I have the code necessary in the artista.js model to display the name of the artist because I have a similar query to display all the artpieces with each artpiece have a genre and an artist.
That example looks like so (to give context):
{
"total": 4,
"productos": [
{
"precio": 0,
"_id": "60c12fca30316c02b9f63519",
"nombre": "GERNICA",
"categoria": {
"_id": "60c04e3605d3c10ed10389e4",
"nombre": "NEO CUBISMO"
},
"artista": {
"_id": "60c136bf30316c02b9f6351b",
"nombre": "PICASSO"
},
"usuario": {
"_id": "609c8c0068e67e68",
"nombre": "Arturo Filio"
}
}
]
}
What am I doing wrong that I can't get my json result at the top look like the json at the bottom, where the artist attribute is?
Also just to point out, I have checked how to nest populate methods in order SO posts including the path and the ref to the Schema and still haven't been able to get the expected result.
I would like to create a "free" schema. A schema where the customer can push his own key/value.
This is my Schema :
const balanceSchema = new mongoose.Schema({
userId: { type: String },
incomes: { type: String },
fees: { type: String }
})
I would like the customer to push in "incomes" ans "fees" categories any key: value he wants, and as much as he wants.
For example, this JSON file :
{
"userId": "9450654064560845",
"incomes": {
"label": 2000,
"label2": 1000,
"label3": 500
},
"fees": {
"fee1": 45,
"mySuperFee": 300
}
}
With the Schemas, I can't push something that is not in the Schema.
Any idea how ?
I'm new in mongoose and I'm trying to find user by code [user.test.test1.code] , any idea ?
Model :
const userSechema = new mongoose.Schema({
name: {
type: String,
required: true
},
test: [{}],
})
Data :
{
"_id": {
"$oid": "600020ab34742c2d34ae45e5"
},
"test": [{
"test1": {
"code": 11111
},
"test2": {
"code": 22222
}
}]
"name": "daniel"
}
query :
let regex = new RegExp(req.query.searchUserKey, 'i')
const users = await User.find({ $or: [{'name': regex },{'test.test1': { code : regex} }]})
-- Solution --
Thanks you guys, both answers is work for me
Is as simple as do "test.test1.code": 418816 into find query like this:
db.collection.find({
"test.test1.code": 418816
})
This query will give you all documents where exists test.test1.code with value 418816.
Note that this query return the whole document, not only the sub-document into the array. But I'm assuming by your post that a user is the document where exists the field name.
Example here
you can use $elemMatch, check the documentation
const users = await User.find(
{ test: { $elemMatch: { "test1.code": 418816 } } }
)
I am trying desperately to find a object stored with mongodb, with nodejs and mongoose.
The model of the object looks like:
const SimpleResourceSchema = new mongoose.Schema(
{
_id: String,
title: String,
objective: String,
url: String,
content: String,
active: Boolean,
type: String,
owner: String,
},
{
timestamps: true,
// _id: false,
}
);
export const SimpleResourceModel = mongoose.model<
SimpleResource & mongoose.Document
>('simpleResource', SimpleResourceSchema);
The query is made with 'id' parameter value '5f1da9737917360dd038bfc0':
return await SimpleResourceModel.findById(id).exec();
The data stored in mongodb is:
{
"_id": {
"$oid": "5f1da9737917360dd038bfc0"
},
"title": "Learn cooking",
"objective": "<p>Is the fridge empty ?</p>",
"content": "...",
"url": "..",
"active": true,
"type": "simple",
"owner": "5efceb2f63b75c1750846b0a",
"createdAt": {
"$date": "2020-07-26T16:04:03.806Z"
},
"updatedAt": {
"$date": "2020-07-26T16:04:03.806Z"
},
"__v": 0
}
I have looked around to get a solution, but have not found any solution to this roadblock.
Anyone can help ?
The main issue that when you define the schema you defined the id as string remove _id: String from schema definition. and it automatic be added.
If you want to add _id to typescript you can create interface
export interface SimpleResource extends Document {
_id: schema.Types.ObjectId,
...
}
then in model you directly add it but _id already defined in Document interface
and make sure that you install #types/mongoose
export const SimpleResourceModel = mongoose.model<SimpleResource>('simpleResource', SimpleResourceSchema);
Have you tried?
var ObjectId = require('mongoose').Types.ObjectId;
return await SimpleResourceModel.findById(new ObjectId(id)).exec();
i still get a null response when I try:
await SimpleResourceModel.findById(mongoose.Types.ObjectId(id)).exec()
I can't push items into MongoDB array every time that i try to push a new element it creates an empty object and i cant figure out why,
I already used the
Collection.Array.push({element})&
Collection.save()
but i cant figure out a solution
This is My Schema
const Schema = mongoose.Schema;
var ParticipantSchema = new Schema({
nom:{Type:String},
prenom:{Type:String},
email:{Type:String}
})
var CompetitionSchema = new Schema({
nom:String,
date:Date,
place:String,
participant :[ParticipantSchema]
})
module.exports = mongoose.model("Competition",CompetitionSchema);
This is my funtion
exports.addParticipant=function(req,res){
var newParticipant={
"nom":req.body.nom,
"prenom":req.body.prenom,
"email":req.body.email
}
Competition.updateOne(
{ _id:req.body.id},
{ $push: { participant: newParticipant } },
(err,done)=>{
return res.json(done)
}
);
}
the result is always an empty object like below
{
"_id": "5ded0eeb85daa100dc5e57bf",
"nom": "Final",
"date": "2019-01-01T23:00:00.000Z",
"place": "Sousse",
"participant": [
{
"_id": "5ded0eeb85daa100dc5e57c0"
},
{
"_id": "5dee3c1b08474e27ac70672e"
}
],
"__v": 0
}
There is no problem in your code, the only problem is that in schema definition you have Type, but it must be type.
If you update your ParticipantSchema like this, it will work:
var ParticipantSchema = new Schema({
nom: { type: String },
prenom: { type: String },
email: { type: String }
});
You are using another Schema in the Array. This results in so-called subdocuments (https://mongoosejs.com/docs/subdocs.html). Mongoose does not populate subdocuments by default. So all you see is just the _id. You can use the populate method to see all subdocuments in detail. ( https://mongoosejs.com/docs/populate.html ) .
Example :
Competition.
find({}).
populate('participant').
exec(function (err, comps) {
//
});
You can either use populate on the Model or on the Document. For populating a document, take a look at https://mongoosejs.com/docs/api.html#document_Document-populate . There is also a auto-populate plugin available via npm but in most cases it's not necessary : https://www.npmjs.com/package/mongoose-autopopulate .
