Не могу понять, где мне просто выполнять вход пользователя (не обновляя данные в базе), а где регистрировать и добавлять в базу нового пользователя. То-есть: если пользователь не зарегистрирован, мы его регистрируем и предлагаем ему ввести имя добавляя данные в базу, а если он уже есть в базе, мы просто логиним его.
