Hello,
I have an issue when trying to using prefetch_related in a queryset
inside a queryset already doing a prefetch_related. I have the
following code:
items = OrderItem.objects.prefetch_related(Prefetch('results'))
orders = Order.objects.prefetch_related(Prefetch('items', queryset=items))
freights = Freight.objects.prefetch_related(Prefetch('orders', queryset=orders))
Which results in the following error:
>
> Cannot find 'items' on OrderItem object, 'items__results' is an invalid
> parameter to prefetch_related()
Models are linked with ForeignKeys (Result => OrderItem => Order => Freight).
What am I doing wrong ?
Thanks.
