I have used CRUD to make a Create page. Once a booking has been made the isAvail boolean is set to False.
What I am trying to do is create an AJAX query so that once the user selects the practice, optician and date the ajax query checks the database to see if the combination of practice, optician and date does not exist alongside isAvail - false in order to prevent double bookings. The ajax query would then return the available times ie - the time where there is no isAvail = false.
