Django - REST Framework Basics

You want to create a ModelSerializer for a Product model but exclude the created_at and updated_at fields from the API output. Which is the best way to do this?

AUse <code>fields = '__all__'</code> and override <code>to_representation</code> to remove those fields.

BRemove those fields from the model definition.

CManually list all fields except those two in <code>fields</code>.

DUse <code>exclude = ['created_at', 'updated_at']</code> in the Meta class.

Step-by-Step Solution

Solution:

Step 1: Understand ModelSerializer field exclusion
ModelSerializer Meta supports an exclude attribute to omit fields easily.
Step 2: Evaluate options
Use exclude = ['created_at', 'updated_at'] in the Meta class. uses exclude correctly. Use fields = '__all__' and override to_representation to remove those fields. is more complex and unnecessary. Manually list all fields except those two in fields. is error-prone and verbose. Remove those fields from the model definition. changes the model, which is not desired.
Final Answer:
Use exclude = ['created_at', 'updated_at'] in the Meta class. -> Option D
Quick Check:

Quick Trick: Use Meta.exclude to omit fields easily [OK]
