Chaining class decorators

The last (i.e. outer) decorator's behavior gets executed first.

def require_authentication_permission(permission):
    def decorator(cls):
        cls.dispatch = method_decorator(
            permission_required(
                permission, raise_exception=True)
            )(cls.dispatch)
        cls2 = class_login_required(cls)
        return cls2

    return decorator

In this case, the execution order is:

1. class_login_required
2. permission_required
