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

Lies... (Not friend pedophile) - Email from Melania to Ghislaine Maxwell: "Dear G, How are you? Nice story about JE in New York Mag. You look great on the picture. I know you are very busy flying all over the world. How was Palm Beach? I cannot wait to go down. Give me a call when you are back in NY. Have a great time! Love, Melania" - Melania Trump: "The lies linking me with the disgraceful Jeffrey Epstein need to end today...I've never been friends with Epstein...I never had a relationship with Epstein or his accomplice Maxwell. My email reply to Maxwell can not be categorized as anything more than casual correspondence." - "Epstein did not introduce me to Donald Trump. I met my husband by chance." - "Donald and I were invited to the same parties as Epstein from time to time." - "I call on Congress to provide the women who have been victimized by Epstein with a public hearing specifically centered around the survivors. We must work openly and transparently to uncover the truth about Epstein." Trump: "She had a right to talk about it because the fake news covers her so inaccurately. Would I have done it that way?" the president mused. "Perhaps not, perhaps, I don't know." @michael_de_adder@rickmckeetoons davegranlundcartoons @mjhiblenart@lowtekguy@tooner13@jackohman60@misterjesseduquette@cdurando49@repeat1968#JeffDanziger@billdaycartoons@billbramhallcartoons@[email protected] #Cartoons#CoffeeAndCourtney#ComicRelief#CartoonCurator ✈️t.me/No_king_No_King
