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

News: Following months of mutual accusations, #Eritrean President Isaias Afwerki accuses #Ethiopia of declaring war, dismisses Red Sea narrative Eritrean President #Isaias Afwerki on Monday accused Ethiopia of declaring war on Eritrea and rejected narratives framing the tensions as a dispute over #Red_Sea access, in comments aired on Eritrean state television. Following an extended discussion on United States foreign policy, President Isaias turned to his deteriorating relations with Ethiopia’s ruling party. He rejected claims that tensions between the two countries are linked to access to the Red Sea, insisting that Eritrea harbors no such ambition. “For us, it is not directly about the Red Sea,” he said. The Eritrean leader accused Ethiopia’s ruling Prosperity Party of advancing a broader militarized agenda, claiming that armed conflicts have persisted across the country despite the signing of the Pretoria peace agreement. Isaias further alleged that ... Read more: https://addisstandard.com/?p=54519
