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

Russian Defence Ministry (@mod_russia_en): ❗️Statement by Russian Defence Ministry ▪️ On March 14, at about 11.30 a.m. Moscow time, Tochka-U tactical missile was fired at a residential block of Donetsk city from the territory controlled by the Kiev nationalist regime. ▪️ The shelling of the city was carried out from the north-western direction, from the area of Krasnoarmeysk settlement, which is controlled by Ukrainian nationalist units. ▪️ As a result of the explosion of a cluster warhead in the center of Donetsk, 20 civilians were killed. Another 28 people, including children, were seriously injured and taken to medical institutions. ▪️ The use of such weapons on a town with no armed forces firing positions, i.e. deliberately targeting civilians, is a war crime. #Ukraine#Donetsk#WarCrime

How a Secluded 1984 Conference Forged Israel’s Unprecedented Influence Over US Media October 31st, 2024 By Kit Klarenberg . In the first week of January 2024, Israeli forces fired 355 bullets at a car containing a five-year-old, then shot at rescue workers who rushed to save her life. An indisputible act of murder, a definite #WarCrime – yet, per many Western media headlines, she was simply a “girl killed in Gaza.” The circumstances and perpetrators of her death, if mentioned at all, were invariably buried at the bottom of reports, well hidden from the 80% of the news-consuming public who only read headlines. In contrast, on October 15 2024, Sky News was very keen that its viewers know the names and faces of four “teenage” #IDF soldiers “killed” in a “#Hezbollah#drone attack,” humanizing and infantilizing individuals who, by mere token of their service in Israel’s military, are by definition, guilty of genocide. .....

🇺🇸#USA #US#Senator#LindseyGraham voices his fear that, due to the International Criminal Court's (#ICC) #WarCrime Charges against Israeli PM #Netanyahu, there might after all even be some adverse #legal consequences for both his own, and his country's, illegal War actions. "If they'll do this to Israel, we're next."
