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

Sometimes, I scrolled back to my previous #thoughts posts so that I can reread and remember what I said to myself to calm myself down & to assure that I can cope, so that I can cope again & again & again – & this is the main reason I started this channel last year & I'm glad I did, although I started to quite neglect it a lot this year 🥺 & I'm thankful for those of you who subscribed and stayed in this channel, especially those who responded to my #poll, interacted with us through our @qw_qwbot, & view our posts, because tbh it makes me feel like there's someone 'listening' to me and that is enough and much appreciated ❤ Thanks dear subscribers. Anyway, just for the update, we only have two admins now; Conan & me, but Conan seems to be occupied with his work since he started working this year, so because of those two reasons mentioned earlier, there might be less frequent posts in this channel 😅 But worry not, because we'll still be providing you with the best #contents we can 🤗 As for the new subscribers, welcome! 🥰🥳 #channelupdate#chupdate @quietworld🍃
