NestedViewSetMixin suport for saving

Is looks like using the NestedViewSetMixin auto generates the filter code for nested routers, but does nothing for saving.

I would recommend something like the following for a URL like companies/company_pk/locations/location_pk:

    def pre_save(self, obj):
        obj.location = Location.objects.get(pk=self.kwargs['location_slug'],
                                    company__pk=self.kwargs['company_pk']
                                    )

to be auto generated so that a user posting to the above URL can omit those fields which are determined by the URL itself.

@chibisov I don’t know if there is a way to find the model from a related field, but I suppose yes.

def create(self, request, *args, **kwargs):
        parents_query = self.get_parents_query_dict()
        request_data = {}

        # insert normal datas
        for key,value in request.data.items():
            request_data[key] = value

        # insert parents datas
        for key,value in parents_query.items():
            request_data[key] = Model.objects.get(pk=value) # instead of 'Model' should be the Foreign key related model object

        serializer = self.get_serializer(data=request_data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

You should add create and update override in NestedViewSetMixin.

I have copied rest_framework implementation of create then I added related datas from parents_query_dict to a new dict and used it in get_serializer instead the base request.data

Edit another way to do this is move all to the serializer create and update

Hi! Why not simple call the self.get_parents_query_dict() for getting all url values?

Edit I’m overriding the base write requests for getting that work. Maybe my work can be included into the extensions to insert automatically url datas in request.data
