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

💿 The Rise and Fall of the Compact Disc Having been hit by the rise of MP3 players in the early 2000s, #CD sales nearly halved between 2000 and 2007, which is when smartphones and the first music streaming services emerged to put the final nail in the compact disc’s little round coffin. #Nostalgia 🚀@PerspectiveIX 🌀 http://prs.pctvix.co/TelegramIX

L'attaccamento agli oggetti é uno degli ostacoli maggiori per la nostra felicità, come se infondessimo in essi parte della nostra anima. #vaporonda#vaporwave#vapourwave#vaporart#seapunk#webpunk#glitch#glitchart#glitchartistscollective#chillwave#aesthetic#vaporwaveaesthetic#vaporwaveaesthetics#malinconia#melancholy#tristezza#sadness#sadboy#lofi#disagio#nostalgia#illusione#illusion#windows95#windows98#windowsxp
