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

Pete Hegseth, Trump’s pick for U.S. Secretary of Defense, openly identifies as a Christian Zionist, backing Israel’s claim to Palestinian land and advocating for the eradication of #Hamas and the Palestinian people. #PeteHegseth#Trump#Israel#Hamas#MiddleEast#Palestine

A new security scandal has hit the #Trump administration as media reports a major data breach exposing senior U.S. security officials’ information online. According to an investigation by the German magazine #DerSpiegel, phone numbers, email addresses, and even passwords belonging to top U.S. security officials were found online. Among those affected are National Security Advisor #MikeWaltz, Vice-President #JDVance, #CIA Director #JohnRatcliffe, White House chief of staff #SusieWiles, U.S. Intelligence Coordinator #TulsiGabbard, and Secretary of Defense #PeteHegseth. The group debated policy and discussed operational details about the impending US military strike on #Yemen – conversations that provided a rare near-real-time look at the inner workings of Trump's senior #nationalsecurity team.
