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

🚀 White House Stablecoin Report Unlikely to Ease Political Hurdles for Clarity Act The White House's recent report on stablecoins is not expected to alleviate political challenges surrounding the Clarity Act, according to TD Cowen. The report suggested that removing stablecoin yield could potentially increase bank lending by $2.1 billion. However, Jaret Seiberg noted that banks are likely to continue opposing cryptocurrency legislation unless it explicitly prohibits stablecoin yield. Seiberg also mentioned last week that there is only a one-in-three chance of the bill passing this year, according to NS3.AI. #WhiteHouse#Stablecoin#ClarityAct#Cryptocurrency#Banking#Legislation#PoliticalChallenges#Finance#TDcowen#NS3AI

Trump's Meme Coin Could Stifle Crypto Progress TD Cowen warns that Trump's TRUMP meme coin may complicate legislative efforts in the crypto market, potentially sparking investigations and increasing partisan tensions. Legislation is predicted to finalize by 2026. In related news, Trump acknowledged TRUMP's success, stating, "I don't know much about it other than I launched it." Recent transactions show $101 million #USDC transferred to Galaxy Digital and over $71 million minted by USDC Treasury. #Trump#Crypto#Legislation#USDC#GalaxyDigital#Altcoin#MemeCoin#Finance#Investigation#WhaleAlert#Tokenomics#DigitalAssets#Securities#MarketTrends#Blockchain#InvestorRelations#TDCowen#Funds#USD#Altman
