4. What is the Django REST framework, and how does it extend Django's capabilities for building APIs?
With the rise of API development, familiarity with Django REST framework is essential. Discuss its features, serializers, views, and authentication classes. Share examples of API development and integration in your projects.
5. Describe the use of Django's class-based views (CBVs) and their advantages over function-based views.
CBVs offer powerful ways to organize your code. Discuss common CBV types like List View and Detail View and their role in creating efficient, reusable views. Provide examples of how you've implemented CBVs in your projects.
6. Explain how Django handles caching, and discuss various caching backends.
Caching is crucial for optimizing performance. Describe Django's caching framework, cache backends (e.g., Memcached and Redis), and how to use caching to improve the speed of your applications.
7. What are Django signals, and how can they be used for decoupled application components?
Django signals enable communication between different parts of your application. Discuss the use of signals for decoupled, event-driven architecture and provide examples of scenarios in which you've employed signals effectively.
