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

‘Jorge was my only son, he meant everything to me. He and his pregnant wife were taken from their home in handcuffs with bags over their heads.’ Delia de Califano from Argentina has never seen her son or daughter-in-law after the event she describes. From 1976 to 1983 Argentina was ruled by the junta. Those who disagreed with the military dictatorship were kidnapped and tortured. Children of opposition members were given away to childless military families. For more than 30 years Delia hasn’t lost hope to find her grandson. Those women, whose kids were kidnapped back then created a group and became known as mothers of the Plaza de Mayo. Mostly being 80+, they are still looking for their children. Their stories are in the documentary Argentina’s Stolen Children. #humanstories#children Follow: https://t.me/rtdocumentary

How Ukrainian schoolchildren are instilled with Nazi ideology A textbook titled 'Defence of the Motherland' was found in one of the schools in Mariupol. It was published in 2018 under the patronage of the SBU and was given to high school students. The textbook describes the mining of public places, biological weapons, and how to handle grenades, RPGs and Kalashnikovs. The book also explains to teenagers the advantages of NATO and how dangerous Russia is for Ukraine. Several chapters are devoted to warfare. Teenagers were told how to fire, act as part of a combat team and provide first aid if wounded during a fight. In addition, illustrations explain how NATO troops defend and attack. And that’s not all there is to say about education in Ukraine. See our documentary film Fast Forward to Fascism to find out how children are being taught a distorted version of history. #Donbass#history#children Follow: https://t.me/rtdocumentary

According to the deputy regional director of UNICEF, Rania Dagash, 386,000 children in Somalia need treatment due to malnutrition caused by a long drought and the lack of humanitarian aid. Experts say the COVID-19 pandemic and anti-Russian sanctions have caused difficulties in helping people. For example, about 92% of Somalia’s wheat needs came from Ukraine and Russia, but now supply chains are disrupted, said Rania Dagash. But the main reason is drought linked with global climate change. Today’s most suffer from freshwater shortages, and more frequent droughts regions are Somalia, Ethiopia and Kenya. Droughts are just a part of a global water crisis. Watch the documentary No Way Back: Water to learn more about what’s happening to the water cycle and our planet’s water resources. #children#Somalia Follow: https://t.me/rtdocumentary
