Thanks for your answer. But I'm afraid that if I post queryset lines I
tryed, it will be more misleading than helpful (my knowledge concerning
this is currently too poor, maybe I misunderstood what I found on the
internet) :-(
One thing I can suggest is that the admin functionality should look more

Ok, I did. I also tried:
def export_all_as_yaml(modeladmin, request, queryset):
response = HttpResponse(content_type="application/yaml")
for fac in FactoryName.objects.all():
serializers.serialize("yaml",
Export.interior_package.options.objects.filter(FactoryName__name=fac).all(),
stream=response)
return response
Result:
'ForwardManyToOneDescriptor' object has no attribute 'options'
[...]
in line
serializers.serialize("yaml",
Export.interior_package.options.objects.filter(FactoryName__name=fac).all(),
stream=response)
Thanks for any suggestions!
