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

🤣FOCIL + EIP-8141 enable faster, censorship-resistant transaction inclusion on Ethereum. ⚡️ 這代表未來 Ethereum 在**抗審查能力、隱私應用與帳戶抽象(AA)**層面將進一步強化,提升 L1 的基礎協議競爭力。 #Ethereum#EIP8141#Privacy#Onchain#区块链#以太币#以太坊 ——— 🗣 “Ethereum is going hard.” 以太坊正持續在底層協議層面推進升級。 👇⭐️👇 🤣留言分享觀點 🥲👇

🚀 Ethereum's Upcoming Glamsterdam Upgrade Progresses Amid Development Challenges Ethereum Foundation has released its latest development update, indicating steady progress in the upcoming Glamsterdam upgrade. According to Foresight News, while the implementation of ePBS (protocol-level PBS) is complex, the related development network is stabilizing, and the block-level access lists (BALs) development network is advancing smoothly. The current goal is to launch the first generalized Glamsterdam development network next week if the ePBS development network remains stable, followed by client releases, security audits, and test network testing. Additionally, EIP-7954, aimed at increasing the maximum contract size, is likely to be prioritized. The subsequent Hegotá upgrade has selected FOCIL (EIP-7805) as the core feature for the consensus layer, while the proposal for account abstraction (AA), EIP-8141, remains in a pending introduction (CFI) status due to lack of consensus. Non-core feature proposals for Hegotá were initiated on April 9. Regarding the network gas limit, the current benchmark target is set at 60 million, with higher limit testing ongoing. As for the upgrade timeline, Glamsterdam is unlikely to go live in the second quarter, and the progress of Hegotá will largely depend on the completion of the former. #Ethereum#Glamsterdam#ePBS#BALs#EIP7954#Hegotá#FOCIL#EIP7805#AccountAbstraction#EIP8141#Blockchain#Crypto#Upgrade#Development#ETH
