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

From Alexander Dugin: “As you all know, as a result of a terrorist attack carried out by the Nazi Ukrainian regime, on August 20, while returning from the Tradition festival near Moscow, my daughter Daria Dugina was brutally killed by an explosion in front of my eyes. She was a beautiful Orthodox girl, a patriot, a military correspondent, an expert on the central channels, and a philosopher. Her speeches and reporting have always been profound, grounded and restrained. She never called for violence and war. She was a rising star at the beginning of her journey. The enemies of Russia meanly, stealthily killed her ... But we, our people, cannot be broken even by such unbearable blows. They wanted to crush our will with bloody terror against the best and most vulnerable of us. But they won't get it. Our hearts yearn for more than just revenge or retribution. It's too petty, not Russian. We only need our Victory. My daughter laid her maiden life on her altar. So win, please! We wanted to raise her to be smart and a hero. Let it inspire the sons of our Fatherland to the feat even now. Farewell to Daria Dugina (Platonova) - a civil memorial service - will take place on August 23 at the Ostankino Television Center at 10 am. Alexander Dugin #ECM#DariaDugina

Un verset du journal de Darya Dugina, qu'elle a tenu pendant les trois dernières années de sa vie. Certaines de ses citations sont utilisées dans le livre, qui est publié à titre posthume « Marais et hauteurs de mon cœur. Journal" : Partir à l'heure et tranquillement, Sans douleur intense et cris forts, Aucune offense et aucun regret Mots vides et doutes. Partir doucement et calmement : Fermer les yeux pour rester un guerrier, Ayant réussi à voir ses proches… Pardonnez-moi, je dois partir. #dariadougina#poemes#dariadugina
