Проблема с register_next_step_handler() используя WebHook. threaded=False

Question

Telegram Bot использует Django 3.2.6, pyTelegramBotAPI 4.0.0. Apache 2.2.29. Cервер использует сертификат от Let’s Encrypt. Бот обрабатывает пошаговый обработчик, однако работоспособность заканчивается на первом шаге. По всей видимости это связанно с переменной:

user_dict = {}

После первого шага переменная становиться пустой и продолжение пошагового обработчика невозможно. Подскажите, пожалуйста как исправить это? Планирую пошаговый обработчик записывать в бд, однако как и запись в бд пошагово, также и отдельным классом не работает.

Telegram Bot интерфейс ошибки

Answer 1

Решено. Через функцию register_next_step_handler() необходимо предать переменную user_dict. Это можно сделать так:

def first_step_reg_org(message):
    try:
        chat_id = message.chat.id
        user = UserReg(message.chat.id)
        user_dict[chat_id] = user
        user.first_name = message.text

        msg = bot.send_message(message.chat.id, registration_messages['last_name'])
        bot.register_next_step_handler(msg, second_step_reg_org, user_dict)
    except Exception as e:
        bot.reply_to(message, f'Что-то пошло не так! first\n{e}')


def second_step_reg_org(message, user_dict):
    try:
        chat_id = message.chat.id
        user = user_dict[chat_id]
        user.last_name = message.text

        msg = bot.send_message(message.chat.id, registration_messages['email'])
        bot.register_next_step_handler(msg, third_step_reg_org, user_dict)
    except Exception as e:
        bot.reply_to(message, f'Что-то пошло не так! second\n{e}')

Далее пошаговый обработчик полностью работает. Спасибо, кто уделил внимание этому вопросу!
