I had a use case where I had to implement a multiple update endpoint; and for the most part I followed docs https://www.django-rest-framework.org/api-guide/serializers/#customizing-multiple-update
however in my case I could not include the pk/id on the child serializer because this is being used for integration work from an external data source that is unaware of our pks. The instance kwarg that I pass to the ListSerializer is a queryset that filters on an alternate key. This queryset also gets passed as the instance kwarg to the child serializer, where it expects an object instance and not a queryset. The issue manifested as an AttributeError in the validators where a queryset has no attribute pk: on this line https://github.com/encode/django-rest-framework/blob/4abfa28e0879e2df45937ac8c7a9ffa161561955/rest_framework/validators.py#L60 I'm still unsure of how to appropriately pass single instances, or lack thereof to the child serializer for validation. Another thought I had was to override some method on the child (before validation) to set self.instance -- You received this message because you are subscribed to the Google Groups "Django REST framework" group.
