How to use values of map function in other functions? - node.js

Question

I want to use data returned by a map method into another function.
Here is the route schema:
const routeSchema = new mongoose.Schema(
{
Location: {
from: {
type: mongoose.Schema.Types.ObjectId,
ref: "Location",
required: true,
},
to: {
type: mongoose.Schema.Types.ObjectId,
ref: "Location",
required: true,
},
},
busId: {
type: mongoose.Schema.Types.ObjectId,
ref: "Bus",
required: true,
},
date: {
type: String,
required: true,
},
departureTime: {
type: Number,
required: true,
},
arrivalTime: {
type: Number,
required: true,
},
},
{
timestamps: true,
}
);
and here is the booking schema and in booking table routeId is embedded:
const bookingSchema = new mongoose.Schema({
userId: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
required: true,
},
routeId: {
type: mongoose.Schema.Types.ObjectId,
ref: "Route",
required: true,
},
passengers: [
{
name: { type: String, required: true, trim: true },
gender: { type: String, required: true, trim: true },
age: { type: Number, required: true, trim: true },
}],
phone: {
type: Number,
required: true,
},
email: {
type: String,
required: true,
},
bookingDate: {
type: String,
required: true,
},
fare: {
type: Number,
required: true,
},
seats: {
type: [Number],
required: true,
},
departureDetails: [
{
city: { type: String, required: true, trim: true },
location: { type: String, required: true, trim: true },
time: { type: String, required: true, trim: true },
date: { type: String, required: true, trim: true },
},
],
arrivalDetails: [
{
city: { type: String, required: true, trim: true },
location: { type: String, required: true, trim: true },
time: { type: String, required: true, trim: true },
date: { type: String, required: true, trim: true },
},
],
},{
timestamps:true
});
Here is the map function method:
router.get("/trip/single", async (req, res) => {
if (!req.query.from || !req.query.to || !req.query.date) {
return res.send({
error: "Please enter the data to get the trip",
});
}
const { from, to, date } = req.query;
const routes = await Route.find({
"Location.from": from,
"Location.to": to,
"date": date.toString(),
});
const matchedBus = await routes.filter(() =>{
return Route.busId === routes._id
});
const bookings = await Booking.find({
routeId: { $in: matchedBus.map((matchedBus) => matchedBus._id) },
});
console.log(bookings);
const busIdWithSeatsObj = {};
var busData = matchedBus.map(data => data)
console.log(busData);
This busData console is returning this data:
[
{
Location: {
from: new ObjectId("6295f0986f9e32990d8b3488"),
to: new ObjectId("6295f0c06f9e32990d8b348b")
},
_id: new ObjectId("6295f12c6f9e32990d8b348e"),
busId: new ObjectId("6295f0836f9e32990d8b3485"),
date: '2022-06-02',
departureTime: 11,
arrivalTime: 6.3,
createdAt: 2022-05-31T10:42:52.785Z,
updatedAt: 2022-05-31T10:42:52.785Z,
__v: 0
}
]
Now I want to use only busId and date only in the function below:
for (let i = 0; i < matchedBus.length; i++) {
let currentBusSeats = [];
const busBookings = bookings.filter((booking) => {
return (
//Want to use date and busId data in here
//someData === date.toString() &&
//someData === matchedBus[i]._id
);
});
console.log(busBookings);
busBookings.forEach(() => {
currentBusSeats = [...currentBusSeats, ...Booking.seats];
});
busIdWithSeatsObj[matchedBus[i]._id] = currentBusSeats;
}
res.status(200).send({ routes, matchedBus, busIdWithSeatsObj });
});
How can I do that to get the result?

Answer 1

var busData = matchedBus.map(data => data
'use your for loop inside data and you can get you _id value by data._id'
)
