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

🔺Continuation from above @rednile12 💠Regime change isn’t just about removing a leader. To make a country truly “investable,” the entire system has to be rebuilt: ▪️ Laws rewritten ▪️ Courts reshaped ▪️ Contracts redesigned —all to legally lock in foreign investor protections for decades. 🔹 That’s where “rule of law” programs enter the picture. Often run by USAID or the State Department, they’re branded as “democracy promotion” or “good governance.” But Benz argues that, in practice, they frequently reengineer legal systems to favor large foreign corporations. 💠 He points to Mongolia as a textbook case. In 2006, Mongolia’s mining laws were rewritten with help from USAID-linked groups and Western NGOs. The result? Foreign firms gained long-term access to Oyu Tolgoi—one of the world’s largest copper and gold deposits. To make all this socially acceptable, a soft-power ecosystem kicks in: U.S.-funded NGOs, “civil society” initiatives, and media campaigns work to gently prepare public opinion—what Benz bluntly calls “fluffing.” Like fluffing pillows before guests arrive… so large-scale resource extraction doesn’t spark mass resistance. For bigger, more defiant states like Iran and Venezuela, the challenge is far greater. Their size and political history mean enormous budgets are needed to: ▪️ Rewrite major sections of national law ▪️ Loosen foreign ownership rules ▪️ Secure cooperation from local elites ▪️ Prevent populist backlash—like Iran’s 1979 revolution, partly fueled by anger at U.S.-backed elites selling national assets It’s a lot to process—but once you see the pattern, it’s hard to unsee. If you’re trying to understand how soft power, “aid,” and “governance reforms” quietly reshape nations and economies, this lens adds a whole new layer to the news. What do you think—does this match what you’ve observed in global politics? 💬 📡@rednile12 Geopolitics | Multipolarity | Sovereignty | Strategic Reality #Geopolitics#ForeignPolicy#SoftPower#ResourcePolitics#MikeBenz#Venezuela#Iran#Mongolia#Neocolonialism
