Good point, that's actually kind of embarassing. I don't actually
expect to be able to use that syntax but I thought it would be
constructive.
Let me try again:
I have a QuerySet of PlaylistAggregation objects. Each
PlaylistAggregation object is related to one Playlist object. I want
to change my QuerySet to select only the related Playlist objects.
An analogous operation would be:
playlist_aggregates = PlaylistAggregation.objects.order_by('-count')
playlists = [p.playlist for p in playlist_aggregates]
But there are some significant downsides for doing that...namely, the
playlist_aggregates QuerySet is evaluated (if I want to paginate the
results, use generic views, etc. it becomes much harder).
Thanks for your help,
Eric
