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

The Unbalanced Equation Reading Between the Lines of Tibor Nagy’s Diplomatic Signaling The Diplomat’s Blueprint: Nagy’s Calculated Candor (Based on Tibor Nagy’s interview withThe Reporter) Tibor Nagy’s interview was not a casual reflection by a retired diplomat. It was a carefully calibrated act of strategic signaling—a rare moment where the inner logic of U.S. policy toward 🇪🇹 was articulated with unusual bluntness. Wrapped in the practiced composure of a veteran envoy, Nagy’s words offered 🇪🇹 neither reassurance nor partnership, but something more revealing: clarity without comfort. To grasp the interview’s real significance, Ethiopians must do what diplomacy often discourages—read not only what was said, but what was deliberately excluded, & examine how language is used to normalize hierarchy, constrain agency, & predefine acceptable limits of sovereignty. 👉Read the Full Article #RedNileMedia#GERD#NileSovereignty#Geopolitics#TransactionalDiplomacy#AfricanAgency#MultipolarWorld#Somaliland
