Still hoping someone has some insight here. I've been plugging away
at it and am still not finding an answer I can live with as an
engineer.
Currently I'm cheating a bit to filter down by only published objects
in my view like so
tag = get_object_or_404(Tag, slug=slug)
contentitems = tag.taggeditem_set.all()
contentlist = [item for item in contentitems if
item.content_object.status == 'P']
Obviously this seems a bit sloppy and I'm probably better off putting
this in a custom related manager that catches errors if I'm trying to
filter on fields that a model doesn't have (which could happen in
generic models).
It doesn't do well at ordering obviously.
I'm still struggling with this though and am not sure generic tagging
is the way I should be going with this. Still appreciate any insight
out there.
