A simple distinct inner join in Django

[foxfirefey]

Let's say I have ColorProperty and DWThemeColor (which is the through of a ManyToMany between DWTheme and ColorProperty). And I want to get all distinct ColorProperties that belong to DWThemes. This is how:

ColorProperty.objects.filter(dwthemecolor__isnull = False).distinct()

You don't even want to know how long it took me to figure this out, people.
