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

📖Title : The Two Towers ✍️Author : J.R.R. Tolkien ⭐️Rating : 4.50/5 (Goodreads) 📆Published : Nov 11, 1954 ———————————————— Summary:In The Two Towers, the Fellowship is broken. Frodo and Sam continue their perilous journey to Mordor to destroy the One Ring, joined reluctantly by the treacherous yet pitiful Gollum, who becomes both guide and threat. Meanwhile, Aragorn, Legolas, and Gimli pursue the Uruk-hai who have captured Merry and Pippin. Their paths lead to the war-torn kingdom of Rohan, where they aid King Théoden against the forces of Saruman. As darkness spreads and war looms, alliances are tested and hope flickers. The story deepens the moral complexity of the quest, showing how power corrupts and loyalty defines true heroism. ———————————————— #fantasy#fiction#classics#adventure#novels#LOTR@Bookslibraryofficial@free_novellas@thesciencelabs
