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')

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
Newly uncovered hack campaign in Telegram
The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
