Sorry, my initial post had object, which is correct. This is simply
what the generic view is choosing to call the instance - it gets an
instance from the queryset you specify, and calls it 'object'. Again,
if you created your own view, you could call it whatever you like, via
the context dictionary.

As you say in your other post, taskupdate_set should be lower case.
However this isn't a template issue, but simply the way Django creates
the automatic reverse relation - again, see
http://www.djangoproject.com/documentation/db-api/#backward : "[the
reverse relationship] Manager is named FOO_set, where FOO is the
source model name, lowercased." It would be the same if you used it in
the shell, or a custom view.
