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

Israel carried out a secret airstrike on a suspected Syrian nuclear reactor at Al Kibar. The strike occurred just after midnight on 6 September 2007. This operation is known by two names: Operation Outside the Box and Operation Orchard. Israeli fighter jets entered Syrian airspace, dropped bombs, and destroyed the building. The Syrian government denied that the site was a nuclear reactor. American and Israeli intelligence assessed that the facility had a military purpose. After the strike, the International Atomic Energy Agency (IAEA) investigated the site and found evidence of uranium and graphite, which are materials associated with nuclear reactors. The operation was carefully planned to avoid detection and limit civilian casualties. Photographs and reconnaissance after the strike confirmed that the reactor building had been completely destroyed. ✈️🇮🇱☢️ [Read more] @googlefactss #Israel#Syria#Nuclear#OperationOrchard#OperationOutsideTheBox#IAEA#Airstrike
