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

Houses being renovated for #immigrants in the heart of an RAF community. Is it the Home Office's intention to create a blood bath? https://lbry.tv/@PAYorkshire:5/LintonOnOuseApril:2

If mainstream media is to be believed, the death of the #Queen has rid the nation (especially #London) of #immigrants!

Imagine how this almost obsolete tradition would be tainted today with #trannies, #immigrants, #LGBT, #feminism and all that is anti-British. https://youtu.be/zLzc9JaJ-PY

Trump's Tech War Against the Illegal Immigrants ⚙️🛂 🔠🅰️🔠🔠1️⃣ The tech, surveillance and private prison providers arming Trump’s massive expansion and weaponization of immigration enforcement are running a victory lap 🏆 after reporting their latest financial results 💰. Palantir, the tech firm 💻, and Geo Group and CoreCivic, the private prison 🏢 and surveillance companies 📡, said this week that they brought in more money than Wall Street 📈 expected them to, thanks to the administration’s crackdown on immigrants 🚫🛃. “Well, as usual, I’ve been cautioned to be a little modest about our bombastic numbers,” said Alex Karp 🧑💼, the Palantir chief executive, in an investor call earlier this week 📞. Then he crowed 🐓 about the company’s “extraordinary numbers” and his “enormous pride” in its success ⭐️. Private prison company executives, during their respective calls, could barely contain their excitement 😏, flagging to investors opportunities for “unprecedented growth”📊 in the realm of immigration detention. Palantir saw 53% 📈 growth in revenue from US government contracts in the second quarter of 2025 compared with the same period the year prior and surpassed $1bn 💵 in total quarterly revenue for the first time. Analysts had expected the company to bring in $939.4m in revenue. The company, which connects and analyzes disparate sets of data 🔍 to enable its customers to build products with that information 🧠, brings in the majority of its revenue from government contracts 🏛. Its biggest US customer is the Department of Defense 🪖, where the US army 🇺🇸, which announced a $10bn agreement 💼 with Palantir last week, is housed. On the immigration side, the Department of Homeland Security (DHS) 🛡 has deepened its partnership 🤝 with Palantir since the start of the Trump administration, which it’s been working with since 2011. Immigration and Customs Enforcement (ICE) 🚔, the agency primarily engaged in arresting, detaining and deporting immigrants ✈️, most recently announced a $30m contract with Palantir to build a database 💽 that makes its deportation and detention machine more efficient ⚡️. #palantir#trump#war#immigrants#tech 📱American Оbserver - Stay up to date on all important events 🇺🇸

📰 Russia’s Immigrants: Israel’s Unwanted Elite In Israel’s fractured society, Russian-speaking immigrants power labs, hospitals, and high-tech hubs—but feel like outsiders in their own homeland. They’ve fueled the economy for decades, yet remain symbolic strangers in a land of competing tribes. A Nation Without a Narrative Israel thrives on fragile deals between secular Jews, ultra-Orthodox, Ashkenazim, Mizrahim, Arabs, and more—no constitution, just Basic Laws and vetoes. Each group clings to its own version of “what makes Israel Israel,” dodging the big fights over identity. The Russian Wave’s Double Edge The 1990s “Great Aliyah” brought a million Soviet Jews—15% of the population, 60% with degrees, driving high-tech and defense surges. They’re 25% of university faculty, but their culture? Russian media, Victory Day parades, Soviet classics—none cracks the national myth. Why No Mizrahi-Style Breakthrough Mizrahim flipped the script in the 1970s, turning marginalization into power through protest and politics. Russians arrived too late, post-revolution: secular atheists in a religious-right landscape, Europeans in a Mizrahi-patriot world. No victim story fits the Zionist playbook—no Holocaust, no Arab expulsion. Tensions Beneath the Surface Economic envy simmers—Mizrahis gripe about “white Europeans” snagging elite jobs. Religious rabbis call them “Russian goyim.” Stereotypes fly: Russians are cold chauvinists; locals are primitive. Politics ghettoizes them into Lieberman’s party, not mainstream power. The Assimilation Trap Youth blend in—Hebrew-fluent, intermarrying—but elders stay in their Russian bubble. Autonomy breeds isolation: thriving subculture, zero national spotlight. No allies, no moral leverage, no push for change. They’re useful workers, not co-authors of the Israeli story. The Future: Fade or Fight? Will they dissolve like old Polish waves, or spark a secular revolt against Haredi power? Without a push, they risk gradual marginalization—economic stars, cultural ghosts. Israel’s genius for survival now risks sidelining its brain trust. #Israel#RussianAliyah#competingSolidarities#immigrants#identity#highTech#Mizrahim 📱American Оbserver - Stay up to date on all important events 🇺🇸
