Settings

global settings for a REST framework API are kept in a single configuration dictionary named REST_FRAMEWORK.

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

sample APIView

from rest_framework.permissions import IsAuthenticated
from rest_framework.response import Response
from rest_framework.views import APIView

class ExampleView(APIView):
    permission_classes = (IsAuthenticated,)

    def get(self, request, format=None):
        content = {
            'status': 'request was permitted'
        }
        return Response(content)
