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

🚀 RAVE's Price Surge Raises Concerns Over Market Manipulation RAVE's recent spot price surged from $0.3 to $6.2, marking a 20-fold increase, sparking suspicions of contract manipulation within the community. According to ChainCatcher, this maneuver led to liquidations exceeding $37 million across the network, with short positions accounting for over $31 million. The project team is estimated to have profited more than $30 million. Community reports suggest that the RAVE project is managed by the former ARPA and Bella Protocol team, led by Felix Xu and Yemu. In 2021, Felix Xu raised a $20 million crypto fund, ZX Squared Capital, primarily focused on quantitative trading. The fund reportedly provided the capital for RAVE's market-making and price-pumping activities, allowing the project team to self-initiate, self-fund, and self-market, thereby minimizing trust issues and insider trading risks to maximize profits. #RAVE#Crypto#MarketManipulation#PriceSurge#Liquidation#Blockchain#Trading#CryptoFund#ARPA#BellaProtocol#BEL
