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

⚠️ AIR POLLUTION IS A SERIOUS CONCERN! In Quvasoy city, Do‘stlik residential area, the 82-KMK reinforced concrete products manufacturing plant is releasing toxic gases and other harmful substances into the atmosphere on a daily basis. This situation poses a real threat to public health and the environment. Under the current circumstances, a legitimate question arises: ❓ How lawful and acceptable is such activity today? We, as members of the public, respectfully but firmly request: 🔹 a thorough investigation of these emissions, 🔹 verification of whether the enterprise operates in full compliance with environmental and sanitary legislation, 🔹 and the adoption of appropriate measures if violations are identified. 🟢 Clean air is not a privilege — it is a fundamental right of every citizen. 🟢 Public health must take precedence over industrial interests. Responsible authorities should not remain indifferent. The public will continue to monitor this situation closely. #AirPollution #Quvasoy #Dostlik #Environment #PublicHealth #EnvironmentalProtection☘️Read the latest environmental news on the @ekologuz page.

Fergana Region, Fergana District, Mindonobod Neighborhood: We can’t breathe, please help! Our homes are located near an asphalt plant, and due to its operations, dust and emissions enter our homes every day. If you step outside around 5–6 a.m., you can see the air is covered in haze. This situation seriously affects the health of our children: allergies and respiratory problems are increasing. We have repeatedly submitted complaints through the clinic, neighbors, and other organizations, and sent letters to higher authorities, but no measures have been taken. The environmental agency has also failed to address the problem. In addition, next to the asphalt plant, there are Megamix and Alibaster production facilities, whose emissions further worsen the air quality. We are calling on the public and responsible authorities: please pay attention to this air pollution and the threat it poses to our children’s health, and take the necessary measures! #Fergana#Mindonobod#Environment#AirPollution#ChildHealth#AsphaltPlant ☘️ Follow the latest environmental news on @ekologuz.
