Hi List,
I need to check, if a given instance of a Model already exists in the
Database. I cannot check 'instance.pk is None', because there are
manually given PKs (no discussion about this plz).
Up to now I check if 'instance._state.adding' is true. But I don't like
this solution.
Checking 'InstanceModel.objects.exists(pk=self.pk)' generates too much
queries, so this is not acceptable in my case.
