Comment:
After a little more work, I had two more problems directly related to
this. The iterator method of QuerySet and the results_iter method of
Query seem to be calculating the index of the start of the
aggregation_fields incorrectly when also using only/defer. I am a little
less certain of the solution I have working for this.
I have attached the patch for Query because it is a little more involed.
QuerySet iterator() defines aggregate_start on line 204:
{{{aggregate_start = index_start + len(self.model._meta.fields)}}}
I would propose to define it before the existing row 257 as:
{{{aggregate_start = index_start + len(load_fields or
self.model._meta.fields)}}}
