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

🚀 ECB Rate Hike Probability Rises to 50% for April The probability of the European Central Bank (ECB) raising interest rates in April has increased to 50%, according to recent pricing in the money markets. According to Jin10, this marks a significant rise from last Friday when the likelihood was estimated at around 20%.

🚀 Eurozone's Oil Price Sensitivity Exceeds That of the U.S., Bank of America Reports The Eurozone exhibits a significantly higher sensitivity to oil price fluctuations compared to the United States, according to a report by Bank of America. The study reveals that a 10% increase in oil prices results in an inflation impact of approximately 40 basis points and a growth impact exceeding 10 basis points in the Eurozone. These effects are roughly double those observed in the U.S. According to Jin10, the report attributes this heightened sensitivity to the larger share of energy in the European consumer basket and the region's status as a net importer of oil. #Eurozone#OilPriceSensitivity#US#BankOfAmerica#InflationImpact#OilPriceFluctuations#EnergyImport#ConsumerBasket#EconomicGrowth

🚀 Bank of America Revises Economic Forecasts Amid Global Tensions Bank of America has adjusted its economic forecasts for the United States and the Eurozone, citing the impact of ongoing global conflicts. According to Jin10, the bank's report on Friday indicated a downward revision of the U.S. growth forecast for this year by 50 basis points to 2.3%. The direct impact of the conflict accounts for approximately three-quarters of this adjustment. Additionally, the overall inflation forecast has been revised upward by 70 basis points, with core PCE expected to be 30 basis points higher than previously predicted, reaching 3.1% by the end of 2026. In the Eurozone, Bank of America has lowered its growth forecast by 60 basis points and increased its inflation forecast by 160 basis points to 3.3%, with core inflation projected at 2.3%. These adjustments reflect the bank's response to the evolving economic landscape influenced by geopolitical tensions. #BankofAmerica#EconomicForecast#USGrowth#Eurozone#Inflation#GeopoliticalTensions#CorePCE#EconomicAdjustment#GlobalConflicts#FinancialForecast
