I've been searching the Django docs and other resources and haven't
been able to find a good solution to my problem. I have a model with a
remaining records and total records field, and I want to order the
queryset by their quotient, remaining_records / total_records.
x =
models.Data.objects.filter(date=None).extra(select={"e":"CAST(remaining_records
AS FLOAT) / CAST(total_records AS FLOAT)"}).order_by('e')
This is what I have right now, it works, in sqlite and I believe a
minor modification changing FLOAT to DECIMAL will make it work for
mysql, but I want it working with both databases.
So, is there a better way to do this in Django? I know you can
reference fields in a filter with F(), but I can't order by them.
Any suggestions?
