HOWTO get list of model instances that have no tags assigned? #275

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Let's say I have a model, named MyModel, of which some instances have tags 
assigned.  Is there a way, using the django-tagging manager classes, to get a 
list of MyModel instances with no tags assigned?  

Or must I write my own custom queries against the django-tagging models?

It seems this would be possible to do in my own code if I could call 
TagManager._get_usage() and have it return a QuerySet rather than a list, 
because I could then apply my own filters to the returned QuerySet.
