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

🇺🇸#SD This chart keeps repeating the same story. Sharp sell-off → momentum drains → aggressive upside leg follows. Price is now sitting right at that transition point again. 🧩 Downside move looks complete, and the curve is starting to turn — this is where new trends are born, not extended lower. 📉➡️📈 If history rhymes, the next phase is a strong expansion move. Buybacks coming soon 🔥 American Crypto©

🇺🇸#SD Price has completed another clean rounded bottom formation at the lower boundary of the long-term structure. The reaction from this zone is strong and mirrors previous cycle reversals. 🔥 Each prior rounded bottom led to a powerful upside expansion, and the current setup is replicating the same rhythm with high precision. The structure shows clear exhaustion of sellers and a decisive shift in momentum. ⚡️ With the pattern repeating and demand stepping in aggressively, price is now positioned for a sustained bullish continuation toward higher macro levels. The next leg up is not just likely—it’s expected. 🚀 American Crypto©
