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

After the attack launched by the regime’s terrorists yesterday in #Latakia, the modest kiosk of the #Alawite young man Ali was vandalized. Ali used to make a living and support his family from this kiosk, and now his family's only source of income has been cut off. Tweet: https://t.co/FPNJrUBukx

In #Jolani's textbook, you disperse peaceful protesters by bringing FUCKING TANKS. @TheAlawiteEcho Tens of thousands of #Alawites are protesting in the city of #Latakia and all around the Syrian coast, rejecting the Jihadist regime of #Jolani, calling for federalism. The Alawite community has lost thousands of civilians throughout the last year, with thousands more detained. https://t.co/SV7Sb1byDR View tweet

"A new massacre against the #Alawites in the city of #Latakia, in the #Dattour neighborhood, al-Mazar junction. I beg all segments of the Syrian people, especially the #Druze, #Kurds, and any remaining members of the #Sunni community who still have a little humanity left in their hearts, to take to the streets in protest to stop these massacres against the innocent. These #massacres are not from yesterday, they are happening today, and as of moments ago, they are still being carried out by Syrian members of Hay’at Tahrir al-Sham #HTS, wearing their official uniforms. Please, save those who remain." https://t.me/CoastSyrian24/771
