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>',
        ...
    )
}
