    193193Here's the basic algorithm the RSS framework follows, given this class and a 
    …… 
    205205      ``django.core.exceptions.ObjectDoesNotExist`` if given invalid 
    206206      parameters. There's no ``try``/``except`` around the 
    207       ``beats.get_object()`` call, because it's not necessary; that function 
    208       raises ``BeatDoesNotExist`` on failure, and ``BeatDoesNotExist`` is a 
     207      ``Beat.objects.get()`` call, because it's not necessary; that function 
     208      raises ``Beat.DoesNotExist`` on failure, and ``Beat.DoesNotExist`` is a 
    209209      subclass of ``ObjectDoesNotExist``. Raising ``ObjectDoesNotExist`` in 
    210210      ``get_object()`` tells Django to produce a 404 error for that request.
