Name the idea, why it exists, then one short example.
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:
- 1A context processor is
a function that receives the request and returns a dict merged into every template context.
- 2Django uses them for
request, debug, and auth.
- 3Custom processors are a
good place for nav counts, not for per-view queries that belong in the view.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Key takeaway
A context processor is a function that receives the request and returns a dict merged into every template context. Django uses them for request, debug, and auth.
