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

Operations Steering Committee of the EU Global Gateway’s Connectivity for Central Asia #C4CA project brought together consortium partners from Lithuania (CPVA), Latvia (CFCA), Estonia (EGA), Finland (HAUS), and France (Expertise France) in Bishkek, alongside the EU Delegations of Kazakhstan and Kyrgyzstan. As part of the Soft Pillar of the Team Europe Initiative on Digital Connectivity, the meeting reviewed first-year results and outlined priorities for the next phase, focusing on digital connectivity, digital economy development, and reducing connectivity gaps in Central Asia. The project delivered key outputs, including country assessments, digital ecosystem mapping, regional events during ICT Week in Uzbekistan and Digital Bridge, and study visits to Europe, Lithuania, and Finland on cybersecurity and the aerospace sector, in coordination with Central Asian stakeholders.

SpaceLab at Space Tech Forum, Germany 🚀 From 18–20 November 2025, SpaceLab represented Central Asia at the Space Tech Forum in Bremen, Germany, with support from the EU’s Global Gateway Connectivity for Central Asia – Soft Pillar program. At one of Europe’s largest space tech and aerospace events, SpaceLab established new contacts in the European space market, raised awareness of Central Asian innovative services among European industry players, and helped spark interest in the region on the international stage. The participation also contributed to strengthening cooperation between the #EuropeanUnion and #CentralAsia in the space sector and helped position SpaceLab and the broader Central Asian space community as a credible emerging player in the 🌍global space ecosystem. #SpaceTechForum#GlobalGateway#C4CA#EU4CA
