    data = list(self[:REPR_OUTPUT_SIZE + 1])

    result.append("%s.%s" % (qn(alias), qn2(target.column))) 
AttributeError: 'Func' object has no attribute 'column'

django.core.exceptions.FieldError: 
Cannot resolve keyword 'something' into field.

: Ben bir hata alıyorum

Author.objects.annotate(
    name_lower=Func(F('name'), function='lower') 
).distinct('something') 

Bunun için:

Author.objects.annotate(
    name_lower=Func(F('name'), function='lower') 
).values('name_lower').distinct()
