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

🌎 The Amazon rainforest is home to the walking palm tree, which appears to “walk” as it slowly grows new roots to move toward sunlight, gradually shifting its position over years. ✨ #rainforest⚡#plants⚡#adaptation 👉subscribe Interesting Planet

🌎 In South America, the giant water lily grows leaves up to 3 meters wide—strong enough to support a small child’s weight! Its waxy surface and ribbed underside help it float, creating floating “rafts” that shelter fish and frogs in warm, shallow waters. ✨ #plants⚡#nature⚡#adaptation 👉subscribe Interesting Planet

🌎 The corpse flower (Amorphophallus titanum) from Indonesia produces one of the world’s largest and smelliest blooms, reaching over 3 meters tall. The flower emits a strong odor similar to rotting meat, which attracts carrion beetles and flies for pollination. ✨ #plants⚡#botany⚡#biodiversity 👉subscribe Interesting Planet 👉more Channels

🌎 Hidden deep in Western Australia, the rare Kingia australis plant produces tall, grass-like stems crowned with spiky flower heads. Its slow-growing trunk can take up to 150 years to reach just 5 meters, making it one of the region’s botanical oddities. ✨ #plants⚡#botany⚡#biodiversity 👉subscribe Interesting Planet 👉more Channels

🌎 The Hydnora africana is a rare, parasitic plant native to southern Africa. It grows underground, emerging only to bloom with a fleshy, foul-smelling flower that attracts beetles for pollination. Its flowers can take up to a year to develop under the soil. ✨ #plants⚡#biodiversity⚡#botany 👉subscribe Interesting Planet
