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

#Transcript Do you like chocolate? Of course I do - who doesn't? I especially love dark chocolate, especially the ones with a few nuts or sea salt mixed in. Eating a piece of chocolate always adds a little bit of joy to my day. Did you like chocolate as gift? Yes, I did like chocolate as a child! I remember that I would always get so excited when I saw a bar of chocolate, especially during the holidays. It was a special treat for me that I looked forward to every year. I remember that I especially loved the combination of sweet and creamy texture that came with it. Chocolate just felt like happiness in a bar! Did you give chocolate as a present to someone? Yes, I did. It was quite recently. I saw this lovely box of chocolates at the store and decided it would be the perfect gift. I put a lot of thought into it; I wanted to choose something that would really show how much I care about them. After I picked out the chocolates, I wrote a heartfelt card to go with it. I think my friend really appreciated the gesture and I'm glad I chose chocolate as a present. ⚡️@ieltsulugbeks⚡️
