I am almost done following this wonderful video, but I am lost on how I create custom name for the record in rails.  My end goal is to create 4-5 buttons and then name the reservation (or appointment) as the text of the button.  But when I do the params I can manually set the name, but cannot figure out where to name it in the code

body: JSON.stringify({ reservation: { start_time: info.event.start, end_time: info.event.end, name: "test" } })

Thanks for the help and great video
