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

October 13, 2021: Gabby Petito, Texas Governor, Debt ceiling fix, U.S borders, La Palma Volcano October 13, 2021: Gabby Petito, Texas Governor, Debt ceiling fix, U.S borders, La Palma Volcano 1. Gabby Petito, the young woman who vanished on a road trip with her boyfriend and later turned up dead in Wyoming, was killed by strangulation, a local coroner said. 2. Texas Governor Greg Abbott's ban on COVID-19 vaccine mandates will likely be superseded by the Biden administration's plan to require shots for workers, but the dueling rules could take months to sort out in court, creating uncertainty for employers with business in the state. 3. The Democratic-controlled U.S. House of Representatives gave final approval to legislation temporarily raising the government's borrowing limit to $28.9 trillion, pushing off the deadline for debt default only until December. 4. The United States will lift restrictions at its land borders with Canada and Mexico for fully vaccinated foreign nationals in early November, ending historic curbs on non-essential travelers in place since March 2020 to address the COVID-19 pandemic. 5. Over 700 residents were ordered to abandon their homes on the Spanish island of La Palma as red-hot lava advanced towards their neighborhood. #GabbyPetito #Wyoming #TexasGovernor #Covid19 #Vaccines #Biden #Democrats #Republicans #UnitedStates #Debt #Canada #Mexico #Borders #Pandemic #LaPalma #Spain #Volcano #News #Reuters Subscribe: http://smarturl.it/reuterssubscribe Reuters brings you the latest business, finance and breaking news video from around the globe.
