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

📰 U.S. War Crime? Military Used Fake Civilian Plane to Kill Drug Smugglers The Pentagon used a secret aircraft painted to look civilian—no military markings, munitions hidden inside—to strike a boat in September, killing 11. Survivors waved at the plane before a follow-up strike killed them. Legal experts say it's "perfidy," a war crime banned under laws of armed conflict. ​ What's Perfidy? Perfidy = fooling enemies by feigning civilian status, then attacking. U.S. military manuals forbid it. Former Air Force deputy JAG Steven Lepper: "If the aircraft isn't identifiable as a combatant, it shouldn't engage in combat." The boat turned back toward Venezuela after seeing the plane—then got hit. ​ Trump's "War" on Cartels Trump declared a secret armed conflict with 24 gangs/cartels, claiming boat attacks are lawful combat—not murder. But even in war, perfidy is illegal. The military has killed 123 people in 35 boat strikes. Critics say it's all illegal: you can't target civilians without imminent threat, war or not. ​ The Plane: Civilian Look, Military Mission Officials confirmed the aircraft wasn't standard military gray—no visible markings. Plane-spotters saw a white 737 with blue stripe at St. Croix in September. Military claims its transponder broadcast a military tail number—but legal experts say that doesn't count if the boat crew couldn't pick up the signal. ​ Pentagon's Defense Falls Flat Pentagon: "All aircraft undergo legal review." But Trump's team excluded JAGs and ops experts from planning. Defense Secretary Hegseth fired top military lawyers in February. Retired Navy JAG Todd Huntley: legitimate uses exist for such planes (hostage rescue), but not for offensive strikes masquerading as civilian. ​ Survivors Waved, Then Died Video shows two survivors clinging to wreckage, waving at the plane—before a second strike killed them. Targeting shipwrecked survivors is also a war crime. The military has since switched to visible MQ-9 Reapers, though it's unclear if victims could see them. ​ Bottom Line: Trump's cartel "war" just crossed into war crime territory—using fake civilian planes to trick targets, then killing survivors. When the rulebook says "don't," and you do it anyway, whose law applies?. ​ #trump#perfidy#warcrimes#pentagon#cartels 📱American Оbserver - Stay up to date on all important events 🇺🇸
