Ring of Fire made by Israel in #Beirut a few minutes ago. This could be you and you'd STILL be silent.

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

It’s past midnight in #Beirut, and our "shelter" homes in the capital trembled as if there were no tomorrow—courtesy of the terrorist entity, Israel. Location: Chiyah area, Beirut, Lebanon.

Under the world’s complicit silence, Israel continues to flatten clearly residential areas in #Beirut’s southern suburbs. These aren’t military targets. They’re homes. Lives. Futures. This is no accident; it’s a calculated erasure, making sure families have nothing to return to, even if the war ends. This was at 8:00 am today.

Qassem writes about saving this baby in last night's attack by Zionist Israel on the central #Beirut: "This child was lying right here, on the remaining piece of the ceiling. When I reached him, I couldn't believe he could still be alive. But when I saw his eyes looking up at me, and how he grabbed onto me, completely in shock, I didn't know what to feel. This child will grow up, and with him, so will the hatred for this savage entity."

Terrorist Israel issued a warning to evacuate certain areas in #Beirut suburbs. Who will issue a warning for their illegal colonial settlers to RUN?
