What are advanced techniques in FBV and CBV?

What are advanced techniques in FBV and CBV?

FBV (Function-Based View) and CBV (Class-Based View) are two approaches in Django for handling views. Advanced techniques include using mixins for reusable code, leveraging decorators for authentication, and implementing custom view logic.

Can you explain how mixins work in CBV?

Mixins are a way to add reusable functionality to class-based views. You can create a mixin that encapsulates common behavior and then include it in multiple views, promoting DRY (Don't Repeat Yourself) principles.

What are some common mixins used in Django?

Common mixins include LoginRequiredMixin for authentication, PermissionRequiredMixin for permission checks, and FormMixin for handling forms in views.

How do decorators enhance FBV?

Decorators in FBV can be used to add functionality like authentication, caching, or modifying request/response objects without changing the core view logic.

Can you give an example of a custom view logic?

Sure! A custom view logic could involve overriding the get_context_data method in a CBV to add extra context variables to the template.
