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

🗣#Farcaster: Project Acquired by Neynar — What’s Next Recently, the Farcaster founder announced a shift from a social platform toward a crypto-wallet–first model. Yesterday, another major update followed — Farcaster has been acquired by Neynar Neynar is the core infrastructure and API provider for Farcaster (similar to Alchemy or Infura), powering most applications, bots, and tools across the ecosystem. What changes after the acquisition: 🟢 Farcaster founders step away from day-to-day operations to focus on new projects. 🟢 Part of the team joins Neynar, while others exit. 🟢 The protocol will continue operating and is not being shut down. 🟢 The $180 million in raised funding will be returned to investors 🟢 According to the founders, Neynar is the best-positioned team to scale Farcaster further, with a strong focus on developers and infrastructure. What to do now: ✔ Check your Neynar points here Neynar is expected to publish a detailed roadmap soon, outlining their vision for the future of the Farcaster protocol. Crypto Drop Club 👉 SUBSCRIBE
