I'm making an API Rest with node, express, typescript and mongoose. I have a method GET that return this result:
{
"success": true,
"status": 200,
"message": "categories listed",
"data": [
{
"_id": "612650e55fe1ce0de138e2af",
"products": [
{
"_id": "612650e55fe1ce0de138e2b0",

"address": "611e9ccdf47c7a7a9cb1d5d9"
},
"estimatedDelivery": "Wednesday September 1st",
"__v": 0
}
]
}
The problem is that I need to retrieve the object "owner", that is, I need to recover this json:
{
"success": true,
"status": 200,
"message": "categories listed",
"data": [
{
"_id": "612650e55fe1ce0de138e2af",
"products": [

"611e62008cb43f7454787ebc"
],

"title": "PS4",

"__v": 0
},
"averageRating": null,
"id": "610b18f3e2244a187b36f2d7"
},
"quantity": 1,
"price": 400
}
],
"owner": {
"_id": "611d2d39dfcc705972c1ccb8",
"name": "Jaume",
"email": "jaumeparrot2#gmail.com",
"password": "$2a$10$Rv9Rzrff6578feCdDjyeKuarKCSHYRqKp5n5wTi2IWtcLBOupvPgu",
"__v": 0,
"address": "611e9ccdf47c7a7a9cb1d5d9"
},
"estimatedDelivery": "Wednesday September 1st",
"__v": 0
}
]
}
For generate this JSON, I'm using this method:
https://github.com/jparrot92/amazon-clone-back/blob/master/src/controllers/order.ts
To retrieve you should use data.owner. This will give owner details as object.
This is the solution:
const products = await Order.find({ owner: req.user._id })
.populate('owner')
.populate({
path: 'products.productID',
populate: {
path: 'owner',
model: 'Owner',
},
})
.exec();

I want to find the user with _id
Then for that user i want to got to cardsData object
Then in cardsData object i want to got to bankCardsArray
Then in bankCardsArray , i want to update fields of a card with particular id
Const res = findOneAndUpdate(
{ 'cardsData.bankCardsArray._id':card_id },
{ $set{ 'cardsData.bankCardsArray.$.title': req.body.title });
Use "." operator to access nested fields.
Refer these mongodb documentation
query-array-of-documents
query-embedded-documents.
Hope this helps.
I want when a category is deleted. All its child categories and its own categories will be deleted.
For example, I want if the web development category is deleted. All its child categories (delete Django and Django Channel)
{
"statusCode": 200,
"data": {
"categories": [
{
"_id": "62fdfb567bb46dcf93b3717f",

"createdAt": "2022-08-18T08:41:58.826Z",

}
],
"id": "62fdfb567bb46dcf93b3717f"
}
]
}
}
I wrote a code for this which does not work properly and removes only one child from the desired category.
const category = await this.checkExistCategory(id);
const deleteResult = await Category.deleteMany({
$or: [{ _id: category._id }, { parent: category._id }],
});
Thank you very much for helping me!!

I successful to return all the objects in STOCK or all the objects in ORDERS
Through this query
const foundUser= await User.find({"user":req.body.user},("Orders") ).exec()
Now I want to filter the response to include only items where "Trackingnumber" is different from 0
For the sample data I expect to receive only
{
"date": {

You can use an aggregation pipeline with a $filter for this:
db.collection.aggregate([
{
$match: {
"user": "jon"
}
},
{
$project: {
ORDERS: {
$filter: {
input: "$ORDERS",
as: "item",
cond: {$ne: ["$$item.Trackingnumber", 0]}
}
}
}
}
])
Playground example
User.find({"Orders" : {"Trackingnumber": 0} })

I need to filter some users according to some fixed criteria. I have a user collection and a talent collection. The talent collection holds the reference to a master category collection.
What I need is to filter these users according to the category in the talent collection and some keys from the user collection.
For example I need to search for a user whose gender is 'male' and education 'BTech' and will have talents as a programmer and tester
my user collection is like,
{

Talent collection
[
{
"_id": "5f38efef179aca47a0089667",

},
{

"level": "3",
"chars": {
"type": "Fresher",
},
"category": "5f19359250bcf9158c6be573",

],
"createdAt": "2020-08-18T07:08:31.532Z",
"updatedAt": "2020-08-18T19:35:22.899Z",
"__v": 2
}
]
And the category in the above document is a separate one populated to this. the category collection as,
[
{
"_id": "5f19359250bcf9158c6be573",
"status": true,
"title": "Testing",
"description": "Application tester",
"code": "test",
"characteristics": [],
"createdAt": "2020-07-23T07:00:34.221Z",
"updatedAt": "2020-07-23T07:00:34.221Z",
"__v": 0
},
{
"status": true,
"_id": "5f29829a705b4e648c28bc88",
"title": "Designer",
"description": "UI UX Designer",
"code": "uiux",
"createdAt": "2020-08-04T15:45:30.125Z",
"updatedAt": "2020-08-04T15:45:30.125Z",
"__v": 0
},
{
"_id": "5f19357b50bcf9158c6be572",
"status": true,
"title": "programming",
"description": "Java programmer",
"code": "program",
"createdAt": "2020-07-23T07:00:11.137Z",
"updatedAt": "2020-07-23T07:00:11.137Z",
"__v": 0
}
]
So my filter terms will be;
{
categories: ["5f19359250bcf9158c6be573", "5f19357b50bcf9158c6be572"],
minAge: 18,
maxAge: 25,
minHeight: 5,
maxHeight: 6,
minWeight: 50,
maxWeight: 80,
complexion: "white",
gender: "male",
}
And the expected result will be a user have both the above talents and followed conditions,
{
users: { ..User details.. },
medias: { ...medias from the matching talents.. }
}
If there are two collections you need to join them either by primary key or _id with foriegn fields and you can use $lookup with $match to filter down.
Documentation
You need to use $lookup with pipeline,
$match you condition for category match
$lookup to join users collection
$match conditions for users collections fields
$match exclude documents that don't found matching users of criteria passed in conditions
db.talents.aggregate([
{
$match: {
category: { $in: ["5f19359250bcf9158c6be573", "5f19357b50bcf9158c6be572"] }
}
},
{
$lookup: {
from: "users",
as: "users",
let: { userId: "$userId" },
pipeline: [
{
$match: {
$expr: {
$and: [
{ $eq: ["$$userId", "$_id"] },
{ $eq: ["$gender", "Male"] },
{ $eq: ["$education", "Btech"] }
// ... add you other match criteria here
]
}
}
}
]
}
},
{ $match: { users: { $ne: [] } } }
])
