Mongodb Schema issue - node.js

Question

Here i am using Nodejs application to get JSON response from external API.I need to capture few key-value pair of this response and need to save it MongoDB.
I am getting the response properly, but i am unable to save the data in database.
Requirement:
Each time i get this response from External server , i need to save it in table by rewriting any documents if already exists in this collection. Here i have nearly 7 array items in json response , i need to save corresponding key value pair from all of the items automatically .
Model:
var mongoose = require('mongoose');
const getAllUsersDataSchema = new mongoose.Schema({
userRefID:[] ,
userName:[],
divisionId: [{}],
divisionName:[{}],
emailId :[{}],
})
module.exports = getAllUsers = mongoose.model('getAllUsers',getAllUsersDataSchema );
**API Call where i am capturing external API response:**
const express = require('express');
const router = express.Router();
const request = require('request');
const config = require('../config');
const fs = require('fs');
const getAllUsers = require ('../db/getAllUsersListmodel');
var mongoose = require('mongoose');
mongoose.connect ('mongodb://localhost/testdb',{ useUnifiedTopology: true , useNewUrlParser: true });
router.get('/', (req, res) => {
// token in session -> get user data and send it back to the Angular app
var data =fs.readFileSync('../teamlist.txt', {encoding:'utf8'} )
console.log(data);
if (data) {
request(
{
method: 'GET',
url: 'https://api.mypurecloud.com/api/v2/users',
headers: {
'Authorization': 'Bearer ' + data
}
},
// callback
(error, response, body) => {
let userInfoResponse = JSON.parse(body);
res.send(userInfoResponse);
console.log(userInfoResponse.entities.length)
console.log(userInfoResponse.entities[0].division.id)
getAllUsers.create({
userRefID : userInfoResponse.entities.id,
userName: userInfoResponse.entities.name,
divisionId: userInfoResponse.entities.division.id,
divisionName:userInfoResponse.entities.division.name,
emailId:userInfoResponse.entities.primaryContactInfo.address
}, (error,post)=>{
console.log(error,post);
});
}
);
}
// no token -> send nothing
else {
res.send("Token Not Present - Kindly login in back");
}
//console.log(req.session.token);
});
Data is saving in DB but not getting any array data saved in to it.
{
"_id" : ObjectId("5fd998d61439a434983702cd"),
"userRefID" : [ ],
"userName" : [ ],
"__v" : 0
}
This is exact API JSON response i am trying to save it in DB and use it for future references:

Answer 1

Entities is an array of objects, but you are trying to refer to its properties as an object:
userRefID : userInfoResponse.entities.id, // but "entities": [ {"id":"...", "name":"..."} ],
userName: userInfoResponse.entities.name,
You have to collect the data in a loop, and only then insert it into the database:
const usersArray = userInfoResponse.entities.map(el => ({
userRefID : el.id,
userName: el.name,
divisionId: el.division.id,
divisionName: el.division.name,
emailId: el.primaryContactInfo[0].address
}));
getAllUsers.insertMany(usersArray)
