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

🌍 Some earthquake "swarms" can hit the same spot repeatedly over weeks or months, releasing energy in small bursts instead of one big quake—often in volcanic or tectonic hot zones. ✨ #earthquakes⚡#tectonics⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 The planet’s largest earthquake ever measured—a magnitude 9.5—struck Chile in 1960. This event released so much energy it caused land to drop by up to two meters along the coast. ✨ #tectonics⚡#earthquakes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 One of the fastest-moving tectonic faults is in Turkey, with plates shifting up to 23 millimeters per year. This constant motion makes the region prone to frequent, sometimes devastating earthquakes. ✨ #tectonics⚡#earthquakes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some tectonic plate boundaries move so slowly they create “silent earthquakes”—huge shifts that happen over days or weeks, releasing energy without sudden shaking. ✨ #tectonics⚡#earthquakes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 Some large earthquakes can trigger aftershocks that last for months or even years. These smaller quakes are part of the Earth’s ongoing adjustment after a major tectonic shift. ✨ #tectonics⚡#earthquakes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The strongest earthquakes ever recorded can move entire cities by several meters in seconds. In 2011, Japan’s coastline shifted east by up to 5 meters due to a massive plate boundary quake. ✨ #earthquakes⚡#tectonics⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The San Andreas Fault in California allows two massive tectonic plates to slip past each other. This boundary creeps a few centimeters each year but can unleash powerful earthquakes in sudden jolts. ✨ #tectonics⚡#earthquakes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The lithosphere’s tectonic plates move slowly, but sometimes collide to form tall mountain ranges like the Himalayas, linking Earth's rocky shell to the atmosphere and biosphere. ✨ #lithosphere⚡#tectonics⚡#mountains⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 The Himalayas are rising by about 5 millimeters each year as the Indian and Eurasian plates continue to collide. This ongoing uplift makes these mountains among the youngest and fastest-growing on Earth. ✨ #mountains⚡#Himalayas⚡#tectonics⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍
