I need to be able to sort on the aggregate of two annotated columns
So I'd like to do something like this:
c = c.annotate(metric=Sum('results__metric'))
c = c.annotate(metric_prior=Sum('results__metric_prior'))
c = c.annotate(variance=F('metric')-F('metric_prior')) #doesn't work, for demonstrative purposes only
and then:
c = c.order_by('variance')
Does anyone know how to accomplish something like the above?
