What is the main purpose of using nested serializers in Django REST Framework?
ATo replace model serializers with function-based views
BTo speed up database queries automatically
CTo include related model data inside the main serializer output
DTo encrypt API responses for security
Step-by-Step Solution
Solution:

  1. Step 1: Understand what nested serializers do

    Nested serializers allow you to include data from related models inside the main serializer's output, making the API response more organized.

  2. Step 2: Evaluate options against the purpose

    Replacing serializers with views is unrelated. Speeding up queries automatically does not occur. Encrypting responses is not involved. Only including related model data inside the main serializer output matches the purpose.

  3. Final Answer:

    To include related model data inside the main serializer output -> Option C
