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

CVMA Student Wins Top Prize in Human Rights Essay Competition December 10, 2025 – Addis Ababa, Ethiopia In celebration of International Human Rights Day 2025, the Center for Human Rights, in collaboration with the UN Human Rights Office (OHCHR), has announced the winners of its essay competition titled “Our Everyday Essentials: Reclaiming Human Rights in the 21st Century.” We are proud to announce that Yared Ermiyas, a student from the College of Veterinary Medicine and Agriculture at Addis Ababa University, emerged as the first-place winner. His powerful essay, “Remove the Shadow,” eloquently argued that access to education must be a fundamental necessity for every child, not a matter of luck, highlighting the deep emotional and practical connection between education and a dignified life. Yared was awarded a mobile phone prize presented by H.E. Berhanu Adello, Chief Commissioner of the Ethiopian Human Rights Commission (EHRC). Commissioner Adello also extended an offer for Yared to begin an internship attachment at the National Bureau of the Human Rights Commission, providing a valuable opportunity for practical experience in the field. The awards ceremony featured a dynamic panel discussion where Yared and the other winners presented their essays and engaged with fellow students and audience members on critical issues related to freedom of expression and the right to education. The competition, which invited undergraduate students to reflect on the core human rights that shape our daily lives, successfully inspired thoughtful dialogue and showcased the intellectual talent within our university community. Congratulations to Yared Ermiyas and all the participants for raising your voices, sharing your vision, and helping to shape the future of human rights!
