Django Django REST Framework 2

Question 1

What does DRF's `APIView` class provide over Django's standard `View`?

Accepted Answer

Request parsing, authentication, permission checking, and content negotiation for APIs

Answer

APIView wraps Django's View with DRF's Request/Response objects, authentication, permissions, throttling, and content negotiation.

Question 2

What does `serializer.is_valid(raise_exception=True)` do in DRF?

Accepted Answer

Validates the serializer data and automatically returns a 400 response if invalid

Answer

With raise_exception=True, DRF automatically returns a 400 Bad Request response with validation errors instead of requiring manual error handling.

Question 3

What is DRF's `Router` used for?

Accepted Answer

Automatically generating URL patterns for ViewSet actions

Answer

Registering a ViewSet with a Router auto-creates standard REST URL patterns for list, detail, create, update, and delete actions.

Question 4

Which DRF permission class allows unrestricted access to an endpoint?

Accepted Answer

AllowAny

Answer

AllowAny grants access to any request, authenticated or not, and is useful for public endpoints like registration or password reset.

Question 5

What does DRF's `@action` decorator do on a ViewSet method?

Accepted Answer

Creates a custom endpoint on the ViewSet beyond the standard CRUD actions

Answer

The @action decorator defines additional routes on a ViewSet, specifying detail=True for object-level actions or False for collection-level actions.
