Restructure json based on actual and expected data - node.js

I want to restructure json based on original json data and the expected json data.
If you look closely in the original json data I have country outside of the Male/Female attributes. I would want the country module to be inside the Male/ Female attribute based on the orientation attribute inside the country module. So in the afterdata I would have 1 country module in Male attribute(since there is 1 male record) and 2 country module in Female attribute(since there are 2 female records).
Original json data looks like this:
{
"Implementations": [
{
"Male": {
"Gender": "Male"
},
"Female": {
"Gender": "Female"
},
"Country": [
{
"Orientation": "Male",
"Name": ABCD
},
{
"Orientation": "Female",
"Name": EFGH
},
{
"Orientation": "Female",
"Name": IJKL
}
],
"State": [
{
"Address": "XYZ Street",
"ZipCode": "US"
}
]
}
]
}
Expected json data:
{
"Implementations": [
{
"Male": {
"Gender": "Male"
"Country": [
{
"Orientation": "Male",
"Name": ABCD
}
],
"State": [
{
"Address": "XYZ Street",
"ZipCode": "US"
}
]
},
"Female": {
"Gender": "Female"
"Country": [
{
"Orientation": "Female",
"Name": EFGH
},
{
"Orientation": "Female",
"Name": IJKL
}
],
"State": [
{
"Address": "XYZ Street",
"ZipCode": "US"
}
]
}
}
]
}
Program:
var Implementations = {
"Implementations": [
{
"Male": {
"Gender": "Male"
},
"Female": {
"Gender": "Female"
},
"Country": [
{
"Orientation": "Male",
"Name": ABCD
},
{
"Orientation": "Female",
"Name": EFGH
},
{
"Orientation": "Female",
"Name": IJKL
}
],
"State": [
{
"Address": "XYZ Street",
"ZipCode": "US"
}
]
}
]
}
var output = [];
for (k in Implementations.Implementations.Male) {
var temp = [];
for (j in Implementations.Implementations.Male[k]) {
temp.push({
Country: j
});
}
output.push({
"Implementations": k,
Country: temp
});
}
console.log(output);
Thank you in advance!

Your program does not work because Implementations.Implementations is an array, it doesn't have field named Male.
Here is a working code snippet:
//Original JSON data in question.
var Implementations = {
"Implementations": [
{
"Male": {
"Gender": "Male"
},
"Female": {
"Gender": "Female"
},
"Country": [
{
"Orientation": "Male",
"Name": ABCD
},
{
"Orientation": "Female",
"Name": EFGH
},
{
"Orientation": "Female",
"Name": IJKL
}
],
"State": [
{
"Address": "XYZ Street",
"ZipCode": "US"
}
]
}
]
}
// Program that make the conversion
var finalResult = [];
for (var i=0; i<Implementations.Implementations.length; i++) {
var currentImplementation = Implementations.Implementations[i];
var targetObj = {
"Male": {
"Gender": "Male",
"Country": [],
"State": currentImplementation.State
},
"Female": {
"Gender": "Female",
"Country": [],
"State": currentImplementation.State
}
};
for (var j=0; j<currentImplementation.Country.length; j++) {
var currentCountry = currentImplementation.Country[j];
if (currentCountry.Orientation === 'Male') {
targetObj.Male.Country.push(currentCountry);
} else if (currentCountry.Orientation === 'Female') {
targetObj.Female.Country.push(currentCountry);
}
}
finalResult.push(targetObj);
}
console.log(JSON.stringify(finalResult));

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": {
"$date": "2022-06-02T15:23:58Z"

"SKU": [
"CJNS"
],
"_id": {
"$oid": "6298d61ba6eeec72b78332a9"
}
}
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} })

How to find data based on sub-field name in MongoDB using Mongoose?

There is a sub-field called 'name' in MongoDB Collection (User):
[
{
"teacher": {
"name": "Alex",
"email": "alex#domain.com"
},
"waiter": {
"name": "Feliks",
"email": "feliks#domain.com"
},
"pilot": [
{
"name": "Sam",
"email": "sam#domain.com"
},
{
"name": "alice",
"email": "alice#domain.com"
}
],
},
{
"teacher": {
"name": "max",
"email": "max#domain.com"
},
"waiter": {
"name": "Sam",
"email": "sam#domain.com"
},
"pilot": [
{
"name": "richard",
"email": "richard#domain.com"
},
{
"name": "alice",
"email": "alice#domain.com"
}
],
}
]
How can I find data based on the field 'name'. For example, when I'm looking for 'Sam', it should return me the all documents since 'Sam' is in "waiter" and "pilot" in first and second documents respectively.
I cannot do something like:
User.find({"teacher.name": "Sam", "waiter.name": "Sam", "pilot.name": "Sam" })
This will return me nothing as it is an AND logic. What I need is an OR logic.
You can use the $or operator.
So the query should look like this:
User.find({ $or: [
{ "teacher.name": "Sam" },
{ "waiter.name": "Sam" },
{ "pilot.name": "Sam" }
]
});
Read here for me details.

How can I mutate the json in the following way in javascript

I have been asked in an interview to mutate the array of objects in such a way that the data appears in the following manner
[
{
"companyName": "ABC",
"members": [
{
"id": 13121212,
"firstName": "Ray",
"lastName": "Fernandis",
"points": 1800,
"position": 1
},
{
"id": 13131313,
"firstName": "Carrie",
"lastName": "Yoda",
"points": 1200,
"position": 2
}
]
}]
and the sample data was given below.
[
{
"communityName": "ABC",
"lastUpdateTimestamp": {
"date": {
"year": 2020,
"month": 10,
"day": 7
},
"time": {
"hour": 18,
"minute": 6,
"second": 5,
"nano": 536529000
}
},
"data": {
"listChannelsData": [
{
"channelId": 1234,
"channelName": "BCD",
"members": [
{
"id": 13121212,
"firstName": "Ray",
"lastName": "Fernandis",
"points": 1800,
"position": 1
}
]
}
]
}
},
{
"communityName": "DEF",
"lastUpdateTimestamp": {
"date": {
"year": 2020,
"month": 10,
"day": 7
},
"time": {
"hour": 18,
"minute": 6,
"second": 21,
"nano": 47894000
}
},
"data": {
"listChannelsData": [
{
"channelId": 3421,
"channelName": "GHI",
"members": [
{
"id": 13121212,
"firstName": "Nicholas",
"lastName": "Xin",
"points": 800,

},
{
"id": 13131313,
"firstName": "Carrie",
"lastName": "Yoda",
"points": 1000,
"position": 1
}
]
}
]
}
}
]
The agenda for me was to print the derived json from sample json and I could only figure out this much code which was a courtesy of stackoverflow
function dictionary(data) {
var map = {};
data.forEach(item => {
if (!Array.isArray(map[item.companyName])) {
map[item.companyName] = [item.data.listChannelsData];
} else {
map[item.communityName].push(item.data.listChannelsData);
}
});
return map;
}
console.log(dictionary(data));
But now when I try to pick up the data for the member using another foreach loop, I'm not able to access the data for members. Can anyone help me with the part where I can successfully access the member array and print the company name along side it
Try this code
var newArray = []
data.map((item, index) => {
newArray[index] = {companyName : item.communityName}
newArray[index].members = item.data.listChannelsData[0].members
})
data is the given data.

How to change this response to simple array?

}
],
}
What I am expecting is this

}
Query I am using is for this response is below using aggregation in mongodb, lookup and project which is leading me to the some undesired response
db.collections.aggregate( [
{
$lookup: {
from: 'users',
as: 'Here',
let: {
whoDid: '$whoDid'
},
pipeline: [
{
"$match": { "$expr": { "$eq": ["$_id", "$$whoDid"] } }
},
{
$project: {
_id: 1,
email: 1,
profileImages: 1,
username: 1,
birthday: 1,
phoneNumber: 1,
firstName: 1,
lastName: 1,
fullName: 1,
// age: {$year: "$birthday"}
age: {
$divide: [{ $subtract: [new Date(), "$birthday"] },
(31558464000)]
}
}
}
],
}
},
{
$project:{
Here:1,
_id:0
}
} ,
])
who did table is one of the collection I have where I have stored the user Id and later I am populating the data using lookup
{
"_id" : ObjectId("5ee988eb1aac0022e15dbb7b"),
"whoDid" : ObjectId("5ee97ef2f25d1c1482717be1"),
"toWhomDid" : ObjectId("5ee97ec0f25d1c1482717bdd"),
"modified_at" : ISODate("2020-06-17T03:07:23.217Z"),
"created_at" : ISODate("2020-06-17T03:07:23.217Z"),
"__v" : 0
}
{
"_id" : ObjectId("5ee988eb1aac0022e15dbb7c"),
"whoDid" : ObjectId("5ee97ec0f25d1c1482717bdd"),
"toWhomDid" : ObjectId("5ee97ef2f25d1c1482717be1"),
"modified_at" : ISODate("2020-06-17T03:07:23.220Z"),
"created_at" : ISODate("2020-06-17T03:07:23.220Z"),
"__v" : 0
}
Can anyone suggest me any better option so that I can get a desired respose?
It is possible to use reduce method:
obj.data = obj.data.reduce((a, c) => {
a.push(...c.Here);
return a;
}, [])
An example:
let obj = {
"success": true,
"message": "Result",
"data": [ {
"Here": [ {
"_id": "5ee97ee7f25d1c1482717bdf", "email": "test1#test.io",
"profileImages": [], "username": "test1",
"birthday": "2020-06-11T10:11:32.000Z", "phoneNumber": "+910000000000", "location": "Test Location",
"firstName": "test1", "lastName": "test1",
}
]
},
{
"Here": [ {
"_id": "5ee97ef2f25d1c1482717be1",
"email": "test2#test.io",
"profileImages": [],
"username": "test2",
"birthday": "2020-06-11T10:11:32.000Z",
"phoneNumber": "+910000000000",
"location": "Test Location"
}
]
}
]
};
obj.data = obj.data.reduce((a, c) => {
a.push(...c.Here);
return a;
}, [])
console.log(obj);
Add these extra steps into your aggregation pipeline:
{
$unwind: "$Here"
},
{
$replaceWith: "$Here"
}
MongoPlayground
Note: You can replace $project: { _id: 1, email: 1, ... to this:
{
$addFields:{
age: {
$divide: [{ $subtract: [new Date(), "$birthday"] },(31558464000)]
}
}

I got the response, want to sort the records by user's first name but it is taking from creation date I guess when using sort how can I make it base on user's first name and user's last name please guide

Tried
{
$sort: {
users: 1,
}
},
doesn't help much
Also if I would like to add two field asc desc order what would be the process in MongoDB
Try this hope this will help you !
{
$sort: { "users.first_name": 1 }
},
