I need your help, I try to add(if it not exists) or update if exists datas in an array of Object in MongoDB.
Here is my Model
import { Schema, model } from "mongoose";
const userSchema = new Schema({
firstName: {
type: String,
required: true,
unique: false,
trim: true
},
pseudo: {
type: String,
required: true,
unique: true,
trim: true,
minlength: 3
},
email: {
type: String,
required: false,
trim: true
},
password: {
type: String,
required: true
},
// password2: {
// type: String,
// required: true
// },
tags: {
type: Array,
required: false
},
address: {
type: String,
required: true,
unique: false,
trim: true
},
coord: {
type: Object,
required: false,
unique: false,
trim: true
},
poll: [
{
tag: String,
dates: Array
}
]
},
{
timestamps: true,
});
const User = model('User', userSchema);
export default User;
My route
router.route('/calendar/:email').post((req, res) => {
User.findOne({ email: req.body.email }).then( (user) =>{
console.log("user 1", user)
User.bulkWrite([
{
insertOne: {
"poll": {
"tag": req.body.selectedTag,
"dates": req.body.datesArray
}
}
},
{
updateOne: {
"filter": {
"tag" : req.body.selectedTag
},
"update": {
$set: {
"dates": req.body.datesArray
}
},
}
}
])
})
});
and the datas sended :
email: 'john#gmail.com',
selectedTag: 'work',
dateArray: [ '2020-07-16T22:00:00.000Z' ]
I try many things like by findOneaAndUpdate, but I don't know how to add in the array "poll", objects with tag and the dates associated.
If somebody could help me it would be very nice !
I shoul use add $addToSet or $push, depending if the element is unique or not.
Something like this:
"update": {
"$addToSet": {
"poll": { /*...*/ }
}
}
For reference:

Here i have two mongoose models orders and users which have one to many relationship.
user.model.js
import mongoose from "mongoose";
const userSchema = mongoose.Schema(
{
firstname: {
type: String,
required: [true, "Name is required"],
},
lastname: {
type: String,
required: [true, "LastName is required"],
},
email: {
type: String,
required: [true, "Email is required"],
unique: true,
},
password: {
type: String,
required: [true, "Password is required"],
},
isAdmin: { type: Boolean, default: false },
},
{
timestamps: true,
}
);
const User = mongoose.model("User", userSchema);
export default User;
order.model.js
import mongoose from "mongoose";
const orderSchema = mongoose.Schema(
{
userId: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
},
customerId: { type: String },
paymentIntentId: { type: String },
products: [
{
id: { type: String },
name: { type: String },
category: { type: String },
price: { type: String },
size: { type: String },
color: { type: String },
thumbnail: { type: String },
qty: { type: Number },
},
],
// subTotal: { type: Number, required: true },
total: { type: Number, required: true },
shipping: { type: Object, required: true },
deliveryStatus: { type: String, default: "pending" },
paymentStatus: {
type: String,
required: true,
},
},
{
timestamps: true,
}
);
const Order = mongoose.model("Order", orderSchema);
export default Order;
I have some orders created by different users in my database. Now i am trying to get those specific orders associated with currently logged in user.
order.controller.js
export const getAllOrders = async (req, res) => {
const { _id } = req.user;
// console.log(typeof id);
try {
const orders = await Order.find({userId: _id});
console.log(orders);
res.status(200).json({ orders });
} catch (error) {
res.status(500).json({ msg: error.message });
}
};
I have tried this one but it always return an empty array.
Hello since there is not subcollections in mongodb i have found that you can nest document as an array ! i did that and it worked but what i want is to add a field to that existing array without losing the old ones ! i can do that by fetching the old array and adding the new field to it and returning that array but doing the fetch inside the patch method wouldn't be a good approach ! so is there any other way i can make that happen ?

I have 2 schemas User and Restaurant, and user has an array of restaurants, am trying to reach when deleting the restaurant delete its reference from user automatically, am trying to reach it with the model.pre('remove')..but when I delete a restaurant the reference id it still exist in User.
Here is my User Schema:
const userSchema = new Schema(
{
email: {
type: String,
trim: true,
// required: true,
unique: true,
},
password: {
type: String,
// required: true,
min: 5,

type: String, //mongoose.Schema.Types.ObjectId,
},
restaurants: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Restaurant",
},
],
role: {
roleId: { type: Number, minlength: 1, maxlength: 1, required: true },
roleName: { type: String, trim: true, required: true },
},
// seperated schema
},
{ timestamps: true }
);
export default mongoose.model("User", userSchema);
and here is my Restaurant Schema:
const restaurantSchema = new Schema({
restaurantOwner: { type: mongoose.Schema.Types.ObjectId, ref: "User" },
Name: {
type: String,
trim: true,
},
server: { type: mongoose.Schema.Types.ObjectId, ref: "ServerUser" },
restaurantLinkAccess: {
type: String,
required: true,
trim: true,
unique: true,

});
restaurantSchema.pre("remove", function (next) {
this.model("User")
.update(
{ restaurantSchema: this },
{ $pull: { comments: this._id } },
{ multi: true }
)
.exec(next);
});
export default mongoose.model("Restaurant", restaurantSchema);
I also tried to solve it like this:
restaurantSchema.pre("remove", function (next) {
this.model("User").remove({ $pull: { restaurants: this._id } }, next);
});
Please help.
I'm having an error on my database where the sub array that I push to my database is missing and created a new id which means it detects data pushed inside.
here's the data I pushed. (toDeliver array has 4 objects inside).
I'm trying to send the whole array along with the string outside of the array.
after the request here what I receive on my database which is mongoDB.
the object inside toDeliver array is incomplete and created a ObjectId.
but the string outside of array was save the database.
here's my schema.
const OwnerSchema = mongoose.Schema({
username: {
require: true,
type: String,
},
password: {
require: true,
type: String,
},
isAdmin: {
type: Boolean,
default: true,
},
store: [
{
product_identifier: {
type: String,
require: true,
},
productname: {
type: String,
required: true,
},
price: {
type: Number,
required: true,
},
quantity: {
type: Number,
required: true,
},
categoryfilter: {
type: String,
required: true
},
description: {
type: String,
required: true,
},
specs: {
type: String,
required: true
},
imageBase64: {
type: String,
required: true,
},
timestamp: {
type: String,
required: true,
}
}
],
delivery: [
{
clientname: {
type: String,
required: true
},
address: {
type: String,
required: true
},
email: {
type: String,
required: true
},
number: {
type: Number,
required: true
},
toDeliver: [
{
product_identifier: {
type: String,
require: true,
},
productname: {
type: String,
required: true
},
price: {
type: Number,
required: true
},
}
],
toDeliverPaidViaPaypal: [
{
product_identifier: {

require: true,
},
productname: {
type: String,
required: true
},
price: {
type: Number,
required: true
},
}
]
}
]
});
here's my backend.
export const delivery = async (req,res) => {
const { id } = req.params;
console.log(id);
console.log(req.body);
try {
if(!id) return res.status(404).json({ message: 'ID not found' });
await OwnerModels.findByIdAndUpdate(id,
{
$push: {
delivery:
{
clientname: req.body.delivery[0].clientname,
address: req.body.delivery[0].address,
email: req.body.delivery[0].email,
number: req.body.delivery[0].number,
toDeliver:
[{
product_identifier: req.body.delivery[0].toDeliver.product_identifier,
productname: req.body.delivery[0].toDeliver.productname,
price: req.body.delivery[0].toDeliver.price
}]
,
toDeliverPaidViaPaypal: []
}
}
},
{
new: true,
},(err,res)=> {
if(err) return console.log({ error: err });
console.log({ result: res.delivery });
}).clone();
} catch (error) {
res.status(500).json({ message: 'Server error' });
}
}
hope ya guys can help me. thank you
I think you need to add square brackets around the toDeliver object to make it an array like your console object:
$push: {
delivery: {
clientname: req.body.delivery[0].clientname,
address: req.body.delivery[0].address,
email: req.body.delivery[0].email,
number: req.body.delivery[0].number,
toDeliver: [{
product_identifier: req.body.delivery[0].toDeliver.product_identifier,
productname: req.body.delivery[0].toDeliver.productname,
price: req.body.delivery[0].toDeliver.price
}],
toDeliverPaidViaPaypal: []
}
}
Also add "_id: false" to toDelivery in your schema to repress id from being generated for the sub-object:
toDeliver: [
{
product_identifier: {
type: String,
require: true,
},
productname: {
type: String,
required: true
},
price: {
type: Number,
required: true
},
_id: false,
}
],
I've been trying updateOne, findOneAndUpdate, and update. Nothing has worked. findOne() operation returns the correct documents.
userProfileModel.updateOne(
{ userEmail },
{
$push: {
userFavLocation: payload,
},
},
(err, result) => {
console.log(err);
console.log(result);
}
);
I get this but no change in my document.
{ ok: 0, n: 0, nModified: 0 }
userEmail and payload have the correct value. When I do findOneAndUpdate, it returns correct document but won't push the value.
This is the Schem for the user profile
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const UserProfileSchema = new Schema(
{
userEmail: {
type: String,
required: true,
unique: true,
},
userProfilePictureUrl: {
type: String,
},
userSignUpDate: {
type: Date,
},
userId: {
type: String,
required: true,
unique: true,
},
userFirstName: {
type: String,
required: true,
},
userLastName: {
type: String,
required: true,
},
userGender: {
type: String,
required: true,
},
userBirthday: {
type: Date,
required: true,
},
userCoordinates: {
type: {
type: String,
default: 'Point',
},
coordinates: {
type: [Number],
},
},
userFavFacilities: {
type: Object,
},
userHometown: {
address: Object,
},
userContact: {
friends: Object,
},
userOrganizations: {
organizations: Object,
},
userMessages: {
type: Object,
},
userAlerts: {
type: Object,
},
userRoles: Object,
userFacilities: Object,
},
{ collection: 'userprofilemodels' }
);
UserProfileSchema.index({ location: '2dsphere' });
module.exports = UserProfile = mongoose.model(
'userprofilemodels',
UserProfileSchema
);
You have to add the userFavLocation field to your schema or mongoose won't perform the update.
const UserProfileSchema = new Schema(
{
userEmail: {
type: String,
required: true,
unique: true,
},
userFavLocation: [PUT_ARRAY_ITEM_TYPE_HERE],
...
}
}
