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

🌍 Over 90% of the world’s plastic is not recycled, and much ends up in the oceans. Ocean plastic has been found in Arctic ice and inside some of the deepest-living sea creatures. ✨ #pollution⚡#environment⚡#oceans⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

近期，台湾有用户称在访问 Google 时被网页提示涉及诈骗。受影响的网站还包括 Google 地图及部分新闻网站。ISP 台湾大哥大解释称，问题原因是当日执行防诈骗相关测试。部分网友由此联想到近期通过的《中介法》，认为这可能是台湾 ISP 大规模屏蔽内容的开始。 台湾 NCC 近期通过《數位中介服務法》（简称中介法）草案，称仿效欧盟 Digital Services Act，要求平台对内容进行监管，产生一些争议。有观点认为法律规范不明确，且平台实际管理困难，恐损害言论自由。 https://tw.news.yahoo.com/google首頁被警告是詐騙-044720539.html 1. https://tw.news.yahoo.com/數位中介服務法-數位中介法-中介法-言論自由-正反意見-110307205.html #Taiwan#DNS#Pollution

全球關注環境污染問題，印度是全球排行第三的碳排放國家，僅次美國及中國。為了可以大幅提升可再生能源的使用率及在2070年實現零碳排，同時為降低對中國太陽能材料的依賴，印度宣布將「打造本土太陽能供應鏈」。 外媒分析，中國在太陽能供應鏈市場一直有領導地位，全球達四分之三的太陽能板材料由中國生產出及供應。如果印度未能完善執行計畫，恐造成國內太陽能電池板成本飆升，當地工廠恐怕要蒙受巨大損失。 #印度#環境污染#碳排放#美國#中國#可再生能源#零碳#太陽能#供應鏈#中共#印度加油#india#pollution#carbondioxide#china#USA#supplychain#sunlight #yseedsmedia#籽煤#新聞#熱門新聞#香港人的新聞#香港人#hongkonger#香港加油 Follow and share us: IG: instagram.com/yseedsmedia/ Fb: fb.com/yseedsmedia Tg: t.me/yseedsmedia
