When i tried query with 'annotate', 'union', 'order_by('annotate_field')'
and 'values' at the same time, i got AttributeError('NoneType' object has
no attribute 'split')
ex)
# 1. make 2 query_set
qs1 = Foo.objects.annotate(bar_val=Value(1,
output_field=IntegerField())).filter(bar=False)
qs2 = Foo.objects.annotate(bar_val=Value(2,
output_field=IntegerField())).filter(bar=True)
# 2. union
qs3 = q1.union(q2)
# 3. order_by annotate field
qs4 = q3.order_by('bar_val')
# 4. get values
q4.values('id')
In this case, I confirmed ('id', None) tuple passed by
compiler.query.set_values() in django/db/models/sql/compiler.py
