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

⚠️ ECOLOGICAL VIOLATIONS ARE BEING IGNORED! As of January 25, 2026, the activities of LLC “Ko‘mir Ta’minoti” of Jizzakh region, particularly the Dashtabod coal storage facility, continue to cause direct harm to local residents, while grossly violating environmental and sanitary regulations. Unfortunately, this company continues to operate without complying with basic environmental standards. Coal dust, air pollution, and the absence of protective measures have become a daily problem for the surrounding community. These violations have been reported several times on our Telegram channel. 📌 Most concerning is the fact that: Since December 2025, residents and public representatives have repeatedly submitted official complaints to the responsible authorities, yet: — no effective action has been taken, — no fines have been imposed, — no official explanations have been provided to the public. ❗️ This raises serious questions: Why are environmental violations going unpunished? Why is public health being ignored? We, as citizens and representatives of civil society, demand an urgent review of this situation and request written, official information regarding: — the identified violations, — the measures taken in response, — the fines imposed (or not imposed) on this enterprise. 🟢 Environmental protection is not a formality. 🟢 It is a matter of human health, children’s future, and the right to a clean environment. Responsible authorities must not remain silent. The public will continue to closely monitor this case. #Ecology #EnvironmentalViolations #Dashtabod #Jizzakh #PublicHealth #PublicOversight☘️Read the latest environmental news on the @ekologuz page.
