Использование Pydantic сегодня стало нормой, и это правильно. Но иногда на ревью вижу, что используют его не всегда корректно. Например, метод BaseModel.model_dump() по умолчанию не преобразует стандартные типы, такие как datetime, UUID или Decimal, в простой сериализуемый для JSON вид. Тогда пишут кастмоный сериализатор для этих типов чтобы функция json.dump() не падала с ошибкой. import uuid from datetime import datetime from decimal import Decimal from uuid import UUID from pydantic import BaseModel class MyModel(BaseModel): id: UUID date: datetime value: Decimal obj = MyModel( id=uuid.uuid4(), date=datetime.now(), value='1.23' ) print(obj.model_dump()) # не подходит для json.dump # { # 'id': UUID('4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1'), # 'date': datetime.datetime(2025, 12, 12, 12, 12, 12, 111111), # 'value': Decimal('1.23') # } # добавляем свой кастомный сериализатор json.dumps(obj.model_dump(), cls=MySerializer) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2025-12-12T12:12:12.111111', # 'value': '1.23' # } В данном случае класс MySerializer обрабатывает datetime, UUID и Decimal. Например так: class MySerializer(json.JSONEncoder): def default(self, o): if isinstance(o, Decimal): return str(o) elif isinstance(o, datetime): return o.isoformat() elif isinstance(o, UUID): return str(o) return super().default(o) Специально для тех, кто всё еще так делает - в этом нет необходимости! Pydantic может это сделать сам, просто нужно добавить параметр mode="json". json.dumps(obj.model_dump(mode="json")) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2012-12-12T12:12:12.111111', # 'value': '1.23' # } #pydantic#libs

TON Launches Loyalty Program ❤️ The TON ecosystem has introduced the TON Loyalty Program — a Tapps rewards layer that turns everyday actions in Telegram Mini Apps into collectible points with built-in “cashback.” How Tapps mechanics work: 🔵 Users open any partner Mini App 🔵 They spend Stars (games, purchases, donations — as usual) 🔵 A smart contract automatically credits Star Points to their TON wallet 🔵 Accumulated points can be redeemed for: • Telegram Premium • Exclusive & Rare Telegram Gifts • Surprise Gift-Boxes Why it’s a welcome addition: 🔵 A portion of Stars spent is returned as points 🔵 All Mini Apps share a unified loyalty system 🔵 An on-chain counter shows exactly how many points you’ve earned and for which actions For long-time Star users, it’s a handy form of cashback. For newcomers, it’s a great reason to explore TON Mini Apps and see the benefits firsthand. 🙃 Check your points here #TON#Tapps#Loyalty#TelegramPremium#MiniApps

☀️Meet the Mini App from Architec.ton! Yesterday Architec.ton team have released their wallet, but banks (shares) can still be purchased to receive $ARС tokens and become a co-owner of the project. Currently the price of $BNK is 1.5 $TON (~$11) The team is currently working on fixes. The #swap button is not yet available. The bugs will be fixed within a short time. 🔜About staking and liquidity All $BNK and $ARC were successfully credited to those who purchased them. If anyone has questions, please contact support @architecton_support. 📈$BNK can be staked now if you want to earn $ARC income. Liquidity in $BNK and $ARC has not yet been added to the swap, so it will not be possible to sell them on the DEX now. This was done according to pre-agreed principles in order to prevent a dump, since the task of the project team is to ensure long-term #liquidity due to the demand for our token. However, the team’s plans include entering the stock exchanges. #wallet#tapps#DEX#gamefi#AMA
