Comment (by shaib):
I believe the OP was only using `something` to point out that `name_lower`
doesn't work in spite of being given as an option in the error message.
On a separate note: You should be able to get the query you described
initially with
{{{
Author.objects.annotate(
name_lower=Func(F('name'), function='lower')
).values('name_lower').distinct()
}}}
or something similar.
