#23396 closed Bug (fixed)

Regression in #14334 causes ValueError to be thrown on ValuesQuerySets

Description

check_related_objects shouldn't be called for ValuesQuerySets. This will lead to a ValueError 'Cannot use QuerySet for 'x': Use a QuerySet for 'y when doing something like:

Author.objects.filter(book__in=Author.objects.values_list('pk'))

whereas this is fine: 

Author.objects.filter(book__pk__in=Author.objects.values_list('pk'))

The prior syntax used to work in django <1.8 before #14334 and #23266 were applied.

Pull request with fix and test to follow.
