This line makes me think that promotion_id contains a Promotion
instance, rather than an ID. Is Review.promotion a ForeignKey to
Promotion? If so, you can change these lines:
> # save average to the relevant Promotion
> p_qs = Promotion.objects.filter(id=promotion_id,)
> p=p_qs[0]
> p.av_rating = average
> p.save()
to:
promotion_id.av_rating = average
promotion_id.save()
(Although you might consider renaming the "promotion_id" variable for
clarity.)
