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

📰 Israel & Arab States Tell Trump: Hold Off on Iran Prime Minister Benjamin Netanyahu and a chorus of Arab allies have urged President Trump to delay any military strike on Iran, even as Tehran continues its brutal crackdown on protesters. The message from the region is clear: don’t ignite a war that could engulf the Middle East. “We believe in dialogue and we believe in solving any disagreements at the negotiating table,” said Saudi Minister of State Adel al-Jubeir. Behind the scenes, Qatar, Saudi Arabia, Oman, and Egypt have been coordinating their appeals to Washington, warning that an American attack could trigger a wider regional conflict. At the same time, they’re telling Tehran not to retaliate if the U.S. does strike. Diplomacy, not bombs, is their mantra. Trump’s signals are anything but clear. He claimed Iran has stopped killing protesters—citing “very important sources”—but hasn’t ruled out military action. Last June, he sent a similar ambiguous message before ordering strikes. U.S. officials say options are still on the table, depending on how Iran’s security forces act next. Meanwhile, Iran’s air space was briefly closed, internet is down, and reports suggest thousands have died in the crackdown. Trump has said he could order an attack if the killing continues, even as he denounces protests against his own policies. So who’s really in control? Not the protesters, not the Arab leaders, and maybe not even Trump. The whole region is dancing on a minefield, and everyone’s hoping the next step isn’t a bomb. #Trump#Iran#Israel#ArabStates#MiddleEast#Diplomacy#WarGames 📱American Оbserver - Stay up to date on all important events 🇺🇸
