I face an issue that i can't resolve alone.
I have a MongoDB collection, in this collection i have 1 document atm.
When i use .findById(_id) or .findOne({_id : id}) with the right _id, everything works.
When i use .findById(_id) or .findOne({_id : id}) with the wrong _id (for test purposes), i have no response (no undefined, no null, nothing) from the DB and my request keep running.
Ty for your time, take care !

I get no results, and I don't know why. (DB has documents with this owner id)
As you can see, I've tried using Types.ObjectId but no success yet.
export const getStores = async (

owner: string
platform?: string

console.log('owner', owner); // owner 62210e86f36af71f58022971
const stores = await StoreModel.aggregate([

'stats': 1,
}
}, {
$match: { owner: Types.ObjectId(owner) }
},
]);
if (!stores.length) {
throw ApiError.BadRequest('Stores not found.');
}
return stores;
};

This is my user model code. I am referencing the favorites using dynamic referencing as there are three types of posts that can be added to favorites

This is my controller. I want to get the posts' details added to favorites by using populate but when I run the code it returns the user object not the post details
const getFavorites = asyncHandler(async(req,res) => {
await User.
findById("61b51adfb7b8a64fd87420d3").
populate("favorites").
exec(function (err, story) {
if (err) throw new Error(err);
console.log(story);
});
})
I have a mongoose document that has timestamps option enabled. I want to make decisions based on this timestamps but I noticed something weird according to my understanding.
I tried to get those values the traditional way (document.createdAt) but that returns undefined. But if I use document.get('createdAt') the value comes as in the database. The docs don't say anything about this. My question is: ¿Why timestamps behave this way?
Edit
The schema I'm using has an array of embedded schemas:
const Customer = new mongoose.Schema({
roles: {
type: [{
type: String,
enum: 'app b2b iot'.split(' '),
}],
default: 'app',
set: (value = []) => (value.includes('app')
? value
: value.concat('app')),
},
email: {
address: {
type: String,
trim: true,
lowercase: true,
set(email) {
this._previousEmail = this.email.address
return email
},
},
verified: {
type: Boolean,
},
token: String,
},
nickname: {
type: String,
trim: true,
},
recoveryToken: String,
gender: String,
birthday: String,
lastLogin: Date,
isAnonymous: {
type: Boolean,
default: false,
},
devices: [Device],
});
Device schema:
const Device = new mongoose.Schema({
customer: {
type: ObjectId,
ref: 'Customer',
required: true,
},
handle: {
type: String,
},
platform: {
type: String,
required: true,
set: toLowerCase,
},
info: Mixed,
smartFilterTags: [{
type: String,
}],
paidUntil: Date,
nh: {
tier: String,
_id: {
type: ObjectId,
},
location: {
type: {
type: String,
enum: ['Point'],
default: 'Point',
},
coordinates: [{
type: Number,
}],
},
})
I have a base plugin that apply when I compile models:
function basePlugin(schema) {
schema.add({
archivedAt: Date,
})
schema.set('timestamps', true)
schema.set('toJSON', {
virtuals: true,
})
schema.set('toObject', {
virtuals: true,
})
}
I am creating multi vendor ecommerce platform, with the following schema.
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true, },
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: { type: Schema.Types.ObjectId, ref: 'Product' },
}
);
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [], },
groups: { type: Array, default: [], },
price: { type: Number, default: null, },
unit: { type: String, default: null, },
quantity: { type: Number, default: null, },
description: { type: String, default: null, },
},
);
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
how can i save multiple products while referring to multiple users? Later i want to populate products based on the users.
Your problem is in referencing the collection. In here when you compile your models
var AllUser = mongoose.model('User', user, 'AllUsers');
var Allproducts = mongoose.model('Product', product, 'AllProducts');
you use Product and for database collection you use AllProducts. That's the problem so...try doing it like this
var Users = mongoose.model('Users', user, 'Users');
var Products = mongoose.model('Products', product, 'Products');
Give it a proper naming convention.
Also there is s typo here in this code.. here I have fixed it
var product = new Schema(
{
sku: { type: String, required: true, unique: true },
title: { type: String, required: true },
category: { type: Array, default: [] },
images: { type: Array, default: [] },
groups: { type: Array, default: [] },
price: { type: Number, default: null },
unit: { type: String, default: null },
quantity: { type: Number, default: null },
description: { type: String, default: null}
}
);
also in your user schema
var user = new Schema(
{
uid: { type: String, index: true, unique: true },
firstName: { type: String, required: true, default: null },
lastName: { type: String, default: null, default: null },
userEmail: { type: String, unique: true, required: true, lowercase: true,
},
userProfileImg: { type: String, required: true, default: null },
userDesignation: { type: String, default: null },
userMobile: { type: Number, required: true, default: null },
products: [{ type: Schema.Types.ObjectId, ref: 'Product' }]
}
);
make products as an array type so that you can store multiple product ids
I have this User model:
const userSchema = new Schema({
_id: {
type: Schema.Types.ObjectId,
required: true
},
name: {
type: String,
required: true
},
email: {
type: String,
unique: true,
required: true
},
notification: {
experiment_id: {
type: Schema.Types.ObjectId,
ref: "Experiment",
required: false
},
seen: {
type: Boolean,
required: true,
default: false
}
}
});
And this Experiment model:
const experimentSchema = new Schema(
{
_id: {
type: Schema.Types.ObjectId,
required: true
},
name: {
type: String,
required: true
},
description: {
type: String,
required: true,
default: "No Description"
},
author_id: {
type: Schema.Types.ObjectId,
ref: "User",
required: true
}
);
I am trying to populate from User the experiment_id in notification.
And from this populate, I would like to populate the author_id as well.
I have seen some code like I have done below but I didn't succeed.
I am trying this:
User.find(
{
_id: req.params.currentUserId
},
"notification"
)
.populate({ path: "experiment_id", populate: { path: "author_id" } })
.exec((err, notif) => {
});
I fixed it by adding notification.experiment_id in the path
User.find(
{
_id: req.params.currentUserId
},
"notification"
)
.populate({ path: "notification.experiment_id", populate: { path: "author_id" } })
.exec((err, notif) => {
});
