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

The United States is depleting its tungsten reserves, a resource critical to the military-industrial complex, according to Foreign Policy. 🔗 Tungsten is essential for manufacturing armor-piercing ammunition, missile components, and aviation equipment. Currently, the United States does not commercially produce tungsten and relies heavily on imports, primarily from China, which dominates the global market. 🌍 Since the escalation of conflict in the Middle East, tungsten prices have surged by over 500%. 📈 Expanding production remains challenging due to limited industrial capacity. Sources indicate that the United States is already confronting a tungsten shortage with no immediate resolution in sight. Even prior to the conflict, the Pentagon sought to reduce its dependence on tungsten, though the extent of their success remains uncertain. ⚙️🇺🇸 #conflict 👂More on Trump's Ear ⚠️

News: Risk of renewed #conflict mounts as troop movements reported near #Eritrea–#Tigray border—Bloomberg Addis Abeba—Ethiopia and Eritrea are deploying troops and military equipment near the northern Tigray region, raising the risk of renewed conflict in the Horn of Africa, Bloomberg reported, citing regional diplomats. Sources familiar with the matter told Bloomberg that Ethiopian troops and equipment have been moved northward, including through Bahir Dar, while Eritrean forces have also deployed to areas inside Tigray. Prime Minister Abiy Ahmed this week reiterated Ethiopia’s longstanding ambition to secure access to the Red Sea, describing maritime access as key to overcoming logistical constraints on economic growth. Eritrean state television also broadcast a naval parade in Massawa last week, marking the anniversary of the city’s capture in 1990. https://addisstandard.com/?p=55268
