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

Taehyung live translation 🐻: Good morning, everyone! 🐻: Good afternoon! 🐻: I woke up because the hotel staff came to clean everything. And because of that, I couldn’t go back to sleep. 🐻: Actually, I wanted to sleep a bit more. 🐻: I woke up earlier than expected… so… 🐻: Normally, I can sleep really well, but… I think it’s been like this since I came back from the military. 🐻: Now I wake up at the slightest noise… someone came to clean early and I woke up because of the noise. 🐻: I used to sleep so deeply, but now even a small sound wakes me up completely. Maybe it’s because of the military. 🐻: "How’s Paris?" 🐻: I loved it so much. I really loved it. 🐻: Sorry, but can we use simple English here? It’s hard for me… 🐻: Seriously, ARMYs, I’m sorry, but reading so much English is making me sleepy. 🐻: Is there a way to read this in Korean? Does Weverse have Korean translation? 🐻: This is really hard. 🐻: I love you. #twitter @OUR_7_PRINCES
