I have been working on this project for over a month, and now I’m stuck on an issue where I can’t correctly retrieve or send the variable ‘barber_id’ to the Flask app. The JavaScript code was mostly generated by ChatGPT since I’m new to JS. My main goal is to get suggestions for barbershop name, barber name, and haircut name (each barber can perform different haircuts) from a PostgreSQL database as I type in input fields dynamically.
