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

@RusEmbMalta Press release: 🇷🇺🇦🇲🇰🇿🇰🇬🇧🇾EAEU Turns 10: A Decade of Integration and Growth On May 29, 2014, the Treaty on the Establishment of the Eurasian Economic Union (EAEU) was signed – marking the beginning of a new era of economic integration across Eurasia. Over the past decade, the Union’s five member states – Russia, Armenia, Kazakhstan, Kyrgyzstan, and Belarus – have achieved remarkable results: 📈 In 2024, mutual trade within the EAEU reached nearly $100 billion 💱 Over 90% of settlements were made in national currencies 🌐 International cooperation is expanding rapidly 🔄 The internal market is functioning and evolving steadily 🤝 The EAEU demonstrates resilience amid global turbulence, offering a stable and non-discriminatory framework built on equality, mutual respect, and benefit. Today, the EAEU is a growing center of gravity in international economic relations: 🌍 Four observer states – Uzbekistan, Cuba, Iran and Moldova 🤝 Free trade agreements with Vietnam, Iran, and Serbia 🤝 Non-preferential trade agreement with China 📜 Over 80 cooperation MoUs through the Eurasian Economic Commission 🪙Trade talks are underway with Indonesia, the UAE, Egypt, India, Mongolia, and others 🇱🇧 We welcome potential interest from our Lebanese friends in partnering with the Union. Russia remains a consistent supporter of deeper coordination between the EAEU and other regional structures – including the CIS, ASEAN, and SCO – as part of building a Greater Eurasian Partnership, an idea first proposed by President Vladimir Putin in 2015. 🔗 The EAEU today stands as a model of successful integration – based on trust, equality, and shared benefit. We thank our partners and the Eurasian Economic Commission for their continued cooperation, and we look forward to unlocking even greater potential together – for the benefit of our peoples and businesses. #EAEU#EurasianUnion#Eurasia#EconomicCooperation#Russia#Armenia#Kazakhstan#Kyrgyzstan#Belarus#Trade#EAEUDay2025#RegionalIntegration
