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

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

UN rapporteur: Israel will not stop ‘this madness’ until we make it stop Francesca #Albanese, the #UN’s special #rapporteur on #Palestine on Saturday urged member states to impose sanctions on #Israel along with an arms embargo until it stops “this madness,” “Let’s be clear. As the #ICJ orders Israel to stop its offensive in #Rafah, #Israel instead intensifies its attacks on it,” The International Court of Justice (#ICJ) in its latest ruling ordered Israel to immediately halt its military offensive in #Rafah, a city in southern Gaza where more than 1.5 million displaced Palestinians had sought refuge. “The news I am receiving from the people trapped therein are terrifying, Be sure: Israel will not stop this madness until WE make it stop,” Albanese urged all UN member states to impose #sanctions, arms #embargo and suspend diplomatic and political relations with Israel until it ceases its #genocidal assault.

A legal group submitted to the #UN the most thorough legal analysis of Israel's actions concluding it is committing genocide against Palestinians in Gaza. This is probably the most complete report to date that demonstrates how #Israel's attacks on #Palestinians in #Gaza meet the legal definition of #genocide. It's a 100-page report, by legal experts at #Boston University School of Law, #Cornell Law School, #Yale Law School, and others. The report's conclusion: "Israel has committed the #genocidal acts of #killing, causing serious harm to, and inflicting conditions of life calculated to bring about the physical #destruction of #Palestinians in #Gaza, a protected group that forms a substantial part of the Palestinian people. These #genocidal acts have been motivated by the requisite genocidal intent, as evidenced in this report by the statements of #Israeli leaders, the character of the State and its forces’ conduct against and relating to Palestinians in Gaza, and the direct nexus between them."
