URLRoute request

Model + TemplateData + HTML

Simple meaning

WHY — DRF instead of guessing?

Why interviewers care about DRF:

DRF questions separate people

who only read docs from people who shipped.

Keep it short, concrete,

and tied to Python work.

Stay structured

Name the idea, why it exists, then one short example.

Close cleanly

End with when you use it and one common pitfall.

STEPS — What happens step by step?

Before you speak the answer, walk the interviewer through these steps:

1
DefaultRouter and SimpleRouter bind
viewset actions to URL patterns including optional trailing slashes.
2
They can emit an
API root listing registered viewsets.
3
Custom actions use @action
and get their own routes with a url_path.
4
Give an example
One tiny concrete case you can say aloud.
5
Common mistake
What juniors usually get wrong.
6
Close
When you pick this over the alternative.
