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

Pump Leaks

Pump Result: One of the best pumps we’ve had. The volume crossed an unprecedented $3.2 million in the first 15 minutes, catapulting #LAYER to our 10x target (957%) and making all of our members huge profits, that’s exactly why we’re the best in the world. Our coin held as the top gainers for hours after our signal, demonstrating the real power of our whales and market makers. Even though we saw a huge volume of external selling (very likely coming from the coin team), we truly delivered on the expected exceptional first pump of the year, and things are just going to get better from here. We’re still receiving an overwhelming amount of gratitude messages from members that scored big, and asking for our next pump. No stress, enjoy the profits, we’ll announce it soon. In the meantime, we’re focusing our efforts on never used before marketing strategies to bring in over 1 million new members for our next Kucoin Mega Pump, which will absolutely dwarf anything we’ve seen until now. Stay tuned for our next pump announcement.
