I think the best way is to create a custom manager for the job (check
the documentation for details-managers). In the manager, do a query
that gets all the users with undone jobs by using the filter option
(also see the documentation - making queries). From the resulting
querydict you could count the occurrence of each unique user in the
querydict to form your dictionary. This could be potentially
inefficient so make sure you save the first query in a variable and
work with that variable.
Meanwhile someone else might know a less verbose way to do it.
