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

💡 چرا پیشرَوی خطی تم (Linear Thematic Progression) در آیلتس کاربرد خوبی دارد؟ 🔹 ۱. ایدهها را بهصورت منطقی به هم وصل میکند در این نوع پیشروی، هر جمله ادامهی طبیعی جملهی قبلی است. در نتیجه، examiner احساس نمیکند ایدهها از هم جدا هستند. ✳️ متن مثل زنجیری منسجم و روان جلو میرود. 🔹 ۲. انسجام (Coherence & Cohesion) را بالا میبرد در معیار نمرهدهی آیلتس، انسجام نقش کلیدی دارد. اگر از پیشروی خطی استفاده کنی، ارتباط بین ایدهها کاملاً روشن میشود. ✅ همین باعث نمرهی بالاتر در این معیار میشود. 🔹 ۳. جریان فکری نویسنده واضح است وقتی هر جمله از اطلاعات جملهی قبلی ساخته شود، examiner دقیقاً مسیر استدلالت را میفهمد. در نتیجه، متن علمیتر و حرفهایتر به نظر میرسد. 🔹 ۴. برای گسترش یک ایده عالی است اگر میخواهی یک مفهوم را مرحلهبهمرحله توضیح دهی (مثلاً علت → نتیجه → پیامد)، این نوع پیشروی بهترین انتخاب است. 📘 مثال: > Online education gives students flexibility. This flexibility helps them manage time effectively. Better time management reduces stress and improves performance. 🟢 نتیجه: متن منسجم، طبیعی، و قابلدرک است, دقیقاً همان چیزی که examiner برای Band 9 میخواهد. #IELTSWriting#Cohesion#Coherence#IELTSBand9#AcademicWriting#LinearProgression#WritingTips#IELTSIran#EFL#TEFL#IELTSTeacher
