Как вы реализуете сериализатор для модели с полями Many-to-Many и динамическими свойствами в Django REST Framework?
Для реализации настраиваемой сериализации в Django REST Framework требуется:
1. Создание сериализатора для модели: Используйте serializers.ModelSerializer и определите сериализаторы для всех связанных моделей с Many-to-Many отношениями.
2. Динамические поля: Добавьте SerializerMethodField для обработки свойств, которые требуют динамического вычисления, и определите соответствующий метод.
class BookSerializer(serializers.ModelSerializer): authors = AuthorSerializer(many=True, read_only=True) custom_field = serializers.SerializerMethodField()
class Meta: model = Book fields = ('title', 'authors', 'custom_field')

In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.Библиотека собеса по Python | вопросы с собеседований from vn
