How to create a bot

class AwesomeBot(Bot):

    def __init__(self, token: str):
        super().__init__(token)

    def init_controllers(self):
        UserController(self)

    def handle(self, e):
        self.send_message(12345, traceback.format_exc())
        return True

class UserController(Controller):

    def __init__(self, bot: Bot):
        super().__init__(bot)

    @message_handler(commands=["start"], chat_types=["private"])
    def start_handler(self, message: Message):
        self.bot.send_message(message.chat.id, "Hello!")

How to use database

db = DataBase("users.db", "structure.sql")

You can provide structure.sql to handle the case where the database doesn't exist. It should contain some scripts to define tables or any other what you need.

How to use service

class DAO:

    def __init__(self, db: DataBase):
        self.db = db

    def get_all_users(self):
        return self.db.fetchall("SELECT id, username, money FROM users")

    def find_user_by_id(self, user_id: int):
        return self.db.fetchone("SELECT id, username, money FROM users WHERE id = ?", user_id)

class UserInfo:

    def __init__(self, data: dict):
        self.user_id: int = data.get("id")
        self.username: int = data.get("username")
        self.money: float = data.get("money")

class UserService(Service[UserInfo]):

    def __init__(self, dao: DAO):
        super().__init__(UserInfo, ["id", "username", "money"])
        self.dao = dao

    def get_all(self):
        return self.to_objects(self.dao.get_all_users())

    def find_by_id(self, user_id: int):
        return self.to_object(self.dao.find_user_by_id(user_id))
