Re: Selecting related objects with condition

The easiest way would be to get a list of all closed work items, ordered
by user:

context['work'] = Work.objects.filter(whatever).order_by('user')

{% for work_item in work %}
{% ifchanged %}Display {{work_item.user}}{% endifchanged %}
Display {{ work_item }}
{% endfor %}
