Хочу добавлять записи в бд, при этом брать инфу из параметров запроса. Но получаю ошибку TypeError: The view function for 'drivers_func' did not return a valid response. The function either returned None or ended without a return statement.
Не понимаю в чем дело потому что ещё вчера всё работало, а сегодня это, может я где-то мискликнул или что-то случайно удалил, но все попытки сегодня сделать это рабочим не увенчались успехом.
Получаю ошибку при попытке создать новго driver (
127.0.0.1:5000/drivers/driver/?first_name=Maki&las...)
Это часть которая начинается с

И подскажите пожалуйста как сделать проверку на то есть ли такой пользователь. потому что моя не работает.
За ранее спасибо
