Identify the bug in the following code snippet:

from rest_framework import serializers
from .models import Article

class ArticleSerializer(serializers.ModelSerializer):
    class Meta:
        model = Article
        fields = ['id', 'title', 'content', 'author']

# Later in views.py
from rest_framework.response import Response
from rest_framework.decorators import api_view

@api_view(['POST'])
def create_article(request):
    serializer = ArticleSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data)
    return Response(serializer.errors)

  1. No bug; the code correctly validates, saves, and returns the serialized data

  2. Missing status code in the Response; should use status.HTTP_201_CREATED

  3. Should use serializer.validated_data instead of serializer.data

  4. The decorator should be @api_view(['GET', 'POST']) instead

Show answer & explanation

Correct answer

No bug; the code correctly validates, saves, and returns the serialized data

Explanation

The code is correct; it properly validates data, saves the instance, and returns appropriate responses. The bug would only appear if the Article model requires additional fields or if validation rules are missing.
