19187	qs.values().delete() doesn't work consistently	Anssi Kääriäinen	nobody	"If you do SomeModel.objects.values().delete() you will get a stack trace like this one:
{{{
  File ""/home/akaariai/Programming/django/tests/django/db/models/query.py"", line 525, in delete
    collector.collect(del_query)
  File ""/home/akaariai/Programming/django/tests/django/db/models/deletion.py"", line 195, in collect
    reverse_dependency=reverse_dependency)
  File ""/home/akaariai/Programming/django/tests/django/db/models/deletion.py"", line 105, in add
    if obj not in instances:
  TypeError: unhashable type: 'dict'
}}}

However if the ""fast-path"" deletion route is taken, then the deletion will work.

I think we should make values().delete() and values_list().delete() throw an error explicitly. We might later on want to make values().delete() work, or have special meaning for such queries (see #9519 for example). But for now making sure that this errors consistently seems like a good idea."
