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

🌍 In Borneo’s rainforests, some fig trees act as “keystone species”—their fruit ripens year-round, feeding dozens of animal species when other food is scarce. ✨ #rainforest⚡#biodiversity⚡#tropics⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some tropical rainforests can hold over 400 different tree species in a single hectare—more tree diversity in one spot than all of Europe’s forests combined. ✨ #rainforest⚡#biodiversity⚡#tropics⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In some tropical rainforests, certain trees release chemicals that prevent other plants from growing near them, creating clear zones called "root exclusion areas" on the forest floor. ✨ #rainforest⚡#tropics⚡#biodiversity⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 More than half of the world’s known plant and animal species live in tropical rainforests, even though these forests cover less than 7% of Earth’s land surface. ✨ #rainforest⚡#biodiversity⚡#tropics⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Some rainforests get over 9 meters of rain each year. The Amazon alone releases so much water through plant transpiration that it creates its own cloud systems, influencing weather far beyond its borders. ✨ #rainforest⚡#tropics⚡#climate⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 In tropical rainforests, some plant leaves grow waxy surfaces and pointed tips called "drip tips." These features help water run off quickly, stopping mold and fungi in the damp climate. ✨ #rainforest⚡#tropics⚡#adaptation⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels
