You probably don't want to do this in your model. How about:
from django.core.exceptions import ObjectDoesNotExist
from django.core.http import Http404
def 404_on_dne(wrapped):
def wrapper(*args, **kwargs):
try:
return wrapped(*args, **kwargs)
except ObjectDoesNotExist:
raise Http404
return wrapper
Then you can wrap your views:
@404_on_dne
def my_view(request, arg1, arg2):
obj = Model.objects.get(...)
# do something
I'm not entirely sure that you shouldn't just explicitly handle these exceptions
in your views (you can end up masking some DNE exceptions that are really bugs),
but that's a way to do what you want.
Disclaimer: I haven't tried any of this code. Might have bugs.
