GET request is not working to retrieve data from the db - node.js

Question

I am quite new to node.js and I am writing a GET request to retrieve documents from my database. Here is the definition of my request (in users.js) -
router.get('/', function (req, res, next) {
Booking.find({} ,(err,prevBookings)=>{
if(err) {
res.status(400).send('No previous bookings found.');
}
if(prevBookings[0]) {
res.status(200).send(prevBookings);
}
else{
console.log("no records")
res.status(200).send("No previous bookings found.")
}
});
});
And I have defined these in the index.js file as follows:
router.use('/users', require('./users'))
router.use('/prev', require('./users'))
//and there are other routers here too but totally unrelated to users.js
But, I am getting the following error on Postman:
NotFoundError: Not Found
I know that this error indicates that I am not routing it correctly. But I am not able to identify where I am going wrong. Other routes that I have defined, are working. Could anyone please help me out with this? Thank you :)

Answer 1

I think you're specifying '/prev' twice. If you change your route in users.js to "/", see what happens. I think at the moment the route "/prev/prev" will return a result.
I'm guessing your users.js should look like so:
const express = require("express");
const router = express.Router();
router.get('/', function (req, res, next) {
Booking.find({} ,(err,prevBookings)=>{
if(err) {
res.status(400).send('No previous bookingd found.');
}
if(prevBookings[0]) {
res.status(200).send(prevBookings);
}
else{
console.log("no records")
res.status(200).send("No previous bookings found.")
}
});
});
module.exports = router;
And then at the top level (index.js) or whatever:
app.use("/", router);
router.use('/prev', require('./users'))
This should return the correct result on "/prev"
For the booking model, could you try modifying the mongoose schema like so (adding the { collection: } entry):
var bookingSchema = mongoose.Schema({
_id : {
type: mongoose.Schema.Types.ObjectId,
required: true
},
user_id : {
type: mongoose.Schema.Types.Mixed,
ref: 'User',
required: true
},
places_id : {
type: mongoose.Schema.Types.ObjectId,
ref: 'Place',
required: true
},
fromDate : {
type: Date,
required: true,
default: Date.now()
},
toDate : {
type: Date,
required: true,
default: Date.now()
},
people_count : {
type: String,
required: true
},
package_details : {
type: mongoose.Schema.Types.Mixed
},
total_cost : {
type : Number,
required : true
},
cost : {
type: Number,
required: true
},
// confirmation: {
// type : String,
// required: true
// },
transaction_no : {
type : String,
required : true
}
}, {
collection: 'booking'
}
)
