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

Trump went to war with Iran and discovered his real enemy was the math. According to AP, two weeks after the first US–Israeli strikes, he’s angrier at the media than at Tehran, still can’t explain why the war started or how it ends, and his approval numbers are sliding while oil and fear go up. Americans see dead service members, $100 oil, red stock screens — and hear a president ranting about “unfair coverage” instead of giving them a story that isn’t pure chaos. Budget analysts now peg the war cost at roughly 1 billion dollars a day when you add operations, munitions, deployments, and replenishment — before interest on the debt and long-term care for the wounded. Iran’s regime is still standing, still controlling the streets, still firing back, while Trump manages to look weak at home and reckless abroad: the worst of both worlds for a guy who sells himself as “America First” and “a winner.” So the political headline writes itself: every 24 hours, Washington burns another billion dollars on a war the president can’t explain and can’t win fast — and the only thing collapsing on schedule is his approval rating. #IranWar#Trump#USA#elections#oil#markets#warCost#taxpayers#fakeLeadership#geopolitics 📱American Оbserver - Stay up to date on all important events 🇺🇸

🇺🇸#USA 🇮🇱#Israel #ZOG USCongress critters Guy #Reschenthaler (R-Israel) and Max #Miller (R-Israel) have introduced a bill that would extend the same taxpayer benefits to #US#Taxpayers serving in the #Israeli Military (#IDF) as if they were serving in the #US#military. This comes at a time when the US Military has been experiencing a recruitment crisis, finding itself unable to convince enough decent quality, fit, young people in the USA to join its military.

We’re back again with Sending files to printers to denounce unnecessary war with Iran on behalf of American people. Numerous U.S. lawmakers, international observers, and advocacy groups have condemned the use of U.S. forces and taxpayers' money to fund what they describe as an "illegal" and "unauthorized," war which lasted for weeks with an undefined goal and conclusion. There is growing pressure to stop the use of U.S. taxpayer money to fund the military operations, with some lawmakers refusing to support supplemental funding for what they term a "disastrous" and "unnecessary" conflict. At least 13 U.S. military personnel have been killed, and Trump warned there will likely be more. #NWWI #NO_War_With_Iran #bushnell #trump #Iranwar #Israel #USA #MAGA #taxpayers
