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

#GEX🐟 From: @thekingfisher_liqmap_bot $BTC GEX+ is currently slightly positive but watch out for any downside, it could get slippery and dip pretty deep if a down move getsnstarted...

#GEX🐟 From: @thekingfisher_liqmap_bot Be ready for any downside on $BTC Not saying it WILL happen, but too likely to happen to have a 20x long liquidation price on the table 👀 If you want to long, there's better risk-reward in waiting for local pullbacks

#GEX🐟 From: @thekingfisher_liqmap_bot $ETH GEX shows negative gamma around 2227. Dealers short convexity here. Fuel for volatility if we push. Monitoring the situation… Explosive upside if we reach it 🔥️️️️️️

#GEX🐟 From: @thekingfisher_liqmap_bot $BTC GEX neutral at 70.9k. Dealers not heavily skewed. Means less hedging pressure if we chop around here. Fuel for volatility if we break.

#GEX🐟 From: @thekingfisher_liqmap_bot Options dealers are saying, we buy $BTC for every $ down We sell for every $ up Conclusion, they'll be a price stabilizing force that's fading liqs territory 🎣

#GEX🐟 From: @thekingfisher_liqmap_bot $ETH dealer delta negative around 2091. Suggests dealers are short gamma there. Fuel for volatility if that level triggers. Could see a snap.
