AttributeError with deep Prefetch

[Gagaro]

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.
