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

🇽🇰#Kosovo: Kosovo Police has found yet another cache of weapons, ammunition, and military gear yesterday, after searching the basement of a residential building on Vasilije Ostroški Street in North Mitrovica. Officers recovered multiple assault rifles, hundreds of rounds of ammunition, magazines, a smoke grenade, body armor, and various pieces of military clothing and equipment. No arrests were made, and an investigation into illegal weapons possession is ongoing. This comes as, over the past week, several abandoned weapons caches have been discovered in the north, including one containing hundreds of kilograms of explosives and a practice anti-tank mine. It remains unclear whether the stashes are linked to a specific paramilitary group or a criminal organization. (📸 via @KosovoPolice on FB)

🇽🇰#Kosovo: Kosovo Police have uncovered weapons, ammunition, and explosives in abandoned houses in Zubin Potok, Zvečan, and the North Mitrovica area since the start of this week. Just in North Mitrovica, authorities seized around 140 kg of explosives, which they say were produced in Serbia. The latest seizure was yesterday in Mitrovicë Veri, where police, acting on information from citizens, found several illegal weapons, ammunition, and a VPMA-2 (a practice version of the PMA-2 anti-personnel mine).
