Cannot apply DjangoModelPermissions on a view that does not have `.queryset` property or overrides the `.get_queryset()` method

You probably have set DjangoModelPermissions as a default permission class in your settings. Something like:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.DjangoModelPermissions',
    )
}

DjangoModelPermissions can only be applied to views that have a .queryset property or .get_queryset() method.

Since Tutorial 2 uses FBVs, you probably need to convert it to a CBV or an easy way is to specify a different permission class for that view. You must be using the api_view decorator in your view. You can then define permissions like below:

from rest_framework.decorators import api_view, permission_classes
from rest_framework import permissions

@api_view([..])
@permission_classes((permissions.AllowAny,))
def my_view(request)
    ...

To resolve the renderer error, you need to add the corresponding renderer to your settings.

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.<corresponding_renderer>',
        ...
    )
}

I got it working in another way. My logged in user was the superuser which i have created. So i have created another user from admin and made him staff user and provided all the permissions. Then logged in to admin by that user.

In settings.py file i changed code.

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

And it worked.

In my case, (for tutorial 2, djangorestframework ver 3.7.7), it works when I change settings to:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.AllowAny',
    ]
}
