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

News: Protesters gather at #Knesset to demand government facilitate #Ethiopian immigration Demonstrators gathered outside the Knesset on Sunday demanding that the government facilitate the immigration of approximately 10,000 relatives of #Israelis of Ethiopian descent, given ongoing violence and strife in Ethiopia’s #Tigray region. Protesters said the government has halted immigration from Ethiopia and stopped funding for it, demanding that leaders immediately “reallocate funds to resume immigration and bring to Israel those whose situation continues to deteriorate against the backdrop of the civil war in Ethiopia,” according to a statement from the organization, Power for Aliyah, which assists Ethiopian immigrants. The group estimated that roughly 2,000 protesters came from across the country, mostly from the Ethiopian community, many of whom have family members waiting in Ethiopia to.... https://www.timesofisrael.com/protesters-gather-at-knesset-to-demand-government-facilitate-ethiopian-immigration/

International Court of Justice (#ICJ ) has finally had enough of #Israelis and their #genocidal actions against the #Palestinians of Gaza It has finally decided to do what #SouthAfrica demanded it should have done months ago: • Demand that the #ZioNazis halt their #genocidal slaughter of innocents in #Gaza and that • Israel must ensure access to Gaza for UN genocide investigators

#Irish politician Thomas #Gould (#SinnFein) excoriates the #Israelis in a blistering speech in Irish Parliament: “The world stands by and does nothing while 15,000 #Palestinian children have been #slaughtered..... We saw photos from when the Israelis #burned men, women and children alive.... I hope you burn in hell #Netanyahu!!"
