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

#Lassa fever is a viral infection spread mainly through contact with food or household items contaminated by urine or droppings of infected rats.🐀 To prevent this spread; ✅ Store food in tightly covered containers to keep rodents away. ✅ Dispose of garbage properly and keep your surroundings clean. ✅ Avoid bush burning that drives rats into homes. ✅ Practice good hand hygiene—wash your hands regularly with soap and water. ✅ Seek medical attention immediately if you develop fever, weakness, or bleeding. Stay informed, Stay healthy! #StaySafe#HealthyLiving#NCDCNigeria

#Lassa fever is not caused by witchcraft or spiritual attacks. It is a viral disease transmitted through contact with urine or droppings of an infected rat, contaminated food, or the body fluids of an infected person. Knowing the facts helps us act early and save lives. If you or anyone around you has a persistent fever, visit the nearest health facility immediately. #LassaFever#KnowTheFacts#PublicHealth#NCDCNigeria
