You could use Django's content types, too. from django.contrib.content_types.models import ContentType my_ct = ContentType.objects.get(app_label='my_app', model='MyModel') # ...or you could leave off app_label, if there are no conflicting model names my_ct.get_object_for_this_type(pk=my_pk)
That way you could use get_object_or_404() in your view. Ben On Thu, Jul 15, 2010 at 10:21 AM, Jonathan Hayward < [email protected]> wrote: > Thank you!
