When I execute
{{{
Model.objects.annotate(message_length=Length('message')).order_by('-message_length').update(text="Can
I come on board?")
}}}
I get the error
{{{
FieldError: Cannot resolve keyword 'message_length' into field. Choices
are: message, id, text, x
}}}
because the code ignores the descending case.
