Django - REST Framework Basics

Identify the issue in this DRF serializer code:

from rest_framework import serializers

class ProfileSerializer(serializers.Serializer):
    name = serializers.CharField(max_length=100)
    email = serializers.EmailField()

    def create(self, validated_data):
        return Profile.objects.create(**validated_data)

    def update(self, instance, validated_data):
        instance.name = validated_data.get('name')
        instance.email = validated_data.get('email')
        instance.save()

AThe serializer should inherit from serializers.ModelSerializer instead

BThe update method is missing a return statement for the updated instance

CThe create method should not use **validated_data

DThe email field should be a CharField, not EmailField

Step-by-Step Solution

Solution:

Step 1: Review update method
The update method modifies instance fields and calls save(), but does not return the instance.
Step 2: DRF expects update to return the updated instance
Omitting the return causes errors during serializer.save() calls.
Final Answer:
The update method is missing a return statement for the updated instance -> Option B
Quick Check:
Always return instance in update method [OK]

Quick Trick: Update method must return the updated instance [OK]
