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

My heart is open, and my faith is strong. I trust this Universe. I trust this earth. I trust my Soul. I trust my body. I trust in the wisdom of my heart. I am guided and I am protected. I am grateful that the earth supports me with unconditional love, to be the happiest, best person that I can be. I have so much to be grateful for. I am grateful for all the blessings that I have in my life. I am grateful for the blessings yet to come. I allow gratitude to open my heart to the unimaginable beauty that surrounds me in every moment. I love all of life, and all of life loves me. I am held. I am loved. I belong. I embrace every setback in life as a lesson gifted to me, so that I may learn and grow. I am here on this beautiful earth to explore, learn, teach and become wise. I am using my wisdom, power, and gifts to uplift others and myself. I am willing to show up for every part of myself that longs to heal. I do the work necessary in order to alleviate the suffering in myself, and as I do, I am alleviating the suffering of others… Thank you … @barosmaldives🧘🏻‍♀️#morningyoga #perfectday#heaven#heavenonearth#merkaba#purelove#moodoftheday#positivevibes#spa#serenityspa#harmony#balance#peaceful#barosmaldives#maldives#blissfulbaros#vacation#energy
