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

🌎 The mosquito is considered the deadliest animal on Earth, causing over 700,000 human deaths each year. Mosquitoes spread malaria, dengue, Zika, yellow fever, and other life-threatening diseases across tropical and subtropical regions, making them a major global health threat. ✨ #animals⚡#danger⚡#diseases 👉subscribe Interesting Planet

‘Heart Water’ Disease: ******* Heart water also known as 1. Cowdriosis 2. Nintas 3. Ehrlichiosis. Heart water is a ricketsial disease of ruminats and some wild animals include cattle sheep and goats ans deer in domestic animals the incubation period varies because of dependent of their rout infection and age. ...................#Etiology.................... its a tick born rickettsial diseases caused by Ehrilichia ruminantum (foremaly known as cowdaria ruminuntum) its transmitted by tick genus of Ambylomma #NB cowdariosis is a notifiable disease. .................#Clinical#Sign.................. 1. Neurological signs. * Tremor * head pressing 2. Respiratory signs. * Cough *Nasal discharge. 3. Systemic sign. * Fever * Loss of appetite. 4. Physical examination. * petechiae of mucos membrane. * Tachycardia * Muffled heart sound 5. Very hard kicking 6. Oedema and diarrhoea. ...................#Diagnosis....................... #Post-#Mortum#Examination. 1. a light yellow transudate found * Thorax * Abdomen * Pericardium. 2. Pulmonary oedema 3. Most fetal cases is * Hydropericardium 4. Difinetly diagnosis you have to focus. * Hippocampus (Under gemsa stain ) or histopathology .......#Differential#Diseases.( look like )....... 1. Toxic plant 2. Tetanus ( just look for wound ) 3. Listeriosis. 4. Milk fever (but remeber its depends muturation during or after parturaion) 5. Mineral deficiency 6. And more others related muscles. ..............#Control. (Vector control )................. (Amblyomma hebraeum) 1. Ectoparasiticide control tick those cause diseases specially thse species * Boophilus * Hyalomma .................#Vaccination (young once )............. 1. a live blood vaccine ......................#Treatment......................... during early stage you can use 1.
