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

China Tightens Control Over AI-Generated Content China's Cyberspace Administration has introduced a draft regulation that will require digital platforms to clearly label all AI-generated content. This new regime would mandate visible logos and metadata embedded in texts, images, videos, and audio files created by AI. In some cases, audio content must include voice prompts identifying AI-generation, while videos would display notifications at key points. The proposed rules aim to tighten control over AI-generated material by ensuring accountability. Platforms will also be required to analyze and label any suspicious content that lacks metadata. This move underscores China’s broader vision for stringent regulation of AI technologies and user-generated content, with significant penalties for non-compliance. #AIRegulation#AICompliance#ChinaTech#AIGovernance

China is not showing any sign of a slowdown in building up a national 5G network, even when the coronavirus outbreak has shattered the global supply chain. The total number of 5G base stations will range between 600,000 and 800,000 by the year’s end (c) KrAsia #china#china🇨🇳#5g#technology#tech#chinatech
