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

Two bomber drones launched from #Lebanon successfully crossed into occupied Yafa (#TelAviv), with one striking its intended target. A video captures the rapid drone en route to its destination. The Israeli occupation military, in an attempt to downplay the incident, claimed they tracked the drone from Lebanon and intercepted one of them. Sure..yes..we believe you.

A 2000 km Yemeni ballistic missile lands in Tel Aviv as the Israeli military claims it landed in an open area. Initial reports indicated that the missile may have targeted an electricity facility in southeastern. A Multi-Layered Defence Array failed to intercept the attack. #TelAviv. #Yemen

#Hezbollah Targets #TelAviv Statement from the Islamic Resistance in #Lebanon In support of our steadfast Palestinian people in the Gaza Strip, and in solidarity with their brave and honorable resistance, as well as in defense of Lebanon and its people, the Islamic Resistance launched a "Qader 1" ballistic missile at 6:30 a.m. on Wednesday, September 25, 2024. The target was the headquarters of Mossad in the outskirts of Tel Aviv, the very site responsible for the assassinations of leaders and the detonation of pagers and wireless devices.

https://x.com/SavinoBalzano/status/1934246322661457994?t=U3jTWZPtQ4P-IBwdzQ6NqQ&s=19 Suggerisco a tutti quelli che danno per scontate le ragioni di #Israele di guardare questo breve contributo. Non esiste alcuna prova che l'#Iran si stesse dotando di armi nucleari. Nessuna. Per inciso, se ne parla — e si denuncia — da decenni. L'attacco a #Teheran è stato del tutto deliberato e rappresenta una violazione del diritto internazionale. Non è una novità, evidentemente, che #TelAviv agisca in questo modo. Le vere motivazioni dietro l'iniziativa di #Netanyahu risiedono, con ogni probabilità, nella fragilità del suo governo e nelle difficoltà che il Paese incontra nel portare a termine i propri obiettivi. Se ne facciano una ragione i vari Parenzo d'Italia e d'Europa. Sempre meno numerosi, per fortuna.

#MaherMarwan, nuovo governatore di #Damasco#Siria: "Voglio facilitare le relazioni con #Israele. E' naturale che #TelAviv abbia avuto paura ed è entrata un po' nel territorio siriano e l'abbia un po' bombardato. Non abbiamo problemi con Israele" https://www.npr.org/2024/12/26/nx-s1-5239759/governor-of-damascus-tells-npr-about-the-new-syrian-governments-plans-with-israel
