Comment (by jarshwah):
The second test you added doesn't actually test what akaariai wants
tested. I've made a comment on the new commit though, with a code example
of what type of query needs to be tested. Hope that's clearer.
Copying the test query below:
{{{
vals = list(
Book.objects.annotate(xprice=F('price'))
.filter(xprice__lte=30).values('publisher', 'xprice') #
xprice should now be in the group by clause
.annotate(count=Count('pk')).values('publisher', 'count') #
but xprice won't be in final select list returned
.order_by('publisher'))
}}}
