hard📝 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Check method and parameters
POST method must be defined with self and request parameters. class DoubleView(APIView): def post(self, request): num = request.data.get('number') result = num * 2 return Response({'result': result}, status=200) correctly defines post(self, request).Step 2: Validate data access and response
class DoubleView(APIView): def post(self, request): num = request.data.get('number') result = num * 2 return Response({'result': result}, status=200) safely uses request.data.get('number') and multiplies by 2. It returns Response with status=200 as required.Step 3: Review other options
class DoubleView(APIView): def post(self, request): num = request.data['number'] result = num + num return Response({'result': result}, status=201) uses status=201 (wrong status). class DoubleView(APIView): def get(self, request): num = request.data.get('number') result = num * 2 return Response({'result': result}, status=200) uses get method instead of post. class DoubleView(APIView): def post(self): num = request.data.get('number') result = num * 2 return Response({'result': result}, status=200) misses request parameter in post method.Final Answer:
class DoubleView(APIView): def post(self, request): num = request.data.get('number') result = num * 2 return Response({'result': result}, status=200) -> Option CQuick Check:
POST with request param, multiply, status=200 [OK]
Quick Trick: POST method with request param, multiply, return status 200 [OK]
