Django Django REST Framework

Question 1

What is Django REST Framework (DRF)?

Accepted Answer

A powerful toolkit for building Web APIs on top of Django

Answer

DRF is a third-party package that extends Django with serializers, viewsets, authentication classes, and browsable API tooling for building RESTful APIs.

Question 2

What is a DRF Serializer used for?

Accepted Answer

Converting model instances to Python native types (and back) for API input/output

Answer

Serializers handle data conversion between complex types like Django models and JSON-compatible Python primitives, including validation on input.

Question 3

Which DRF serializer automatically generates fields from a model?

Accepted Answer

ModelSerializer

Answer

ModelSerializer introspects a model to create serializer fields automatically, similar to how ModelForm works for forms.

Question 4

What is a DRF ViewSet?

Accepted Answer

A class that combines CRUD logic for a resource into one class, used with Routers

Answer

A ViewSet groups related views (list, create, retrieve, update, destroy) into one class and works with DRF's Router to auto-generate URL patterns.

Question 5

Which DRF authentication class validates API requests using a token in the Authorization header?

Accepted Answer

TokenAuthentication

Answer

TokenAuthentication expects an 'Authorization: Token <key>' header and validates it against tokens stored in the authtoken_token database table.
