Django - REST Framework Basics

Consider this DRF viewset snippet:

from rest_framework import viewsets
from .models import Order
from .serializers import OrderSerializer

class OrderViewSet(viewsets.ModelViewSet):
    queryset = Order.objects.filter(status='completed')
    serializer_class = OrderSerializer

What will be the result when accessing this API endpoint?

AThe API returns a list of all completed orders serialized by OrderSerializer

BThe API returns all orders regardless of status

CThe API raises an error due to missing permission classes

DThe API returns an empty list because queryset is not defined properly

Step-by-Step Solution

Solution:

Step 1: Analyze the queryset
The queryset filters Order objects with status='completed'.
Step 2: Understand ModelViewSet behavior
ModelViewSet uses the queryset and serializer_class to return serialized data.
Final Answer:
The API returns a list of all completed orders serialized by OrderSerializer -> Option A
Quick Check:
Queryset filters data correctly; no error expected without explicit permissions [OK]

Quick Trick: ModelViewSet uses queryset and serializer_class to serve filtered data [OK]

Common Mistakes:

MISTAKES
