I'm developing a website project that serves as a "Walmart" version of AirBnB.
Here's the functionality of the button in question:
When a user clicks on the "Make Reservation" button on a listing, they are prompted to select a start and end date before submitting. This action triggers an HTTP request to the server.
Unfortunately, I've encountered an error message that reads:
TypeError: Cannot read property 'then' of undefined at /vagrant/LightBnB/LightBnB_WEB_APP/server/apiRoutes.js:44:7 <--
The problematic API route is located at line 44:7 which is as follows:
This section of code is causing the issue:
.then((reservation) => {
res.send(reservation);
The API ROUTE Logic responsible for the problem is illustrated below:
router.post('/reservations', (req, res) => {
const userId = req.session.userId;
database
.addReservation({ ...req.body, guest_id: userId })
.then((reservation) => {
res.send(reservation);
})
.catch((e) => {
console.error(e);
res.send(e);
});
});
This route invokes the addReservation() function defined as follows:
/**
* Add a reservation to the database
* @param {{}} reservation An object containing all of the reservation details.
* @return {Promise<{}>} A promise to the reservation.
*/
const addReservation = function (reservation) {
const queryString = `
INSERT INTO reservations(
start_date,
end_date,
property_id,
guest_id
)
VALUES ($1, $2, $3, $4)
RETURNING *
`;
const values = [
reservation.start_date,
reservation.end_date,
reservation.property_id,
reservation.guest_id,
];
pool
.query(queryString, values)
.then((res) => {
res.rows;
})
.catch((e) => console.log(e.message));
};
exports.addReservation = addReservation;
