Answer 1

rollback serializer to your default

class SaleUserSerializer(serializers.ModelSerializer):

    class Meta:
        model = SaleUser
        fields = ('id', 'comment', 'creation_date', 'modification_date', 'last_user', 'user', 'sale', 'user_sale_type')

and override view to it:

from rest_framework.response import Response    

class SaleUserViewSet(ModelViewSet):
    queryset = SaleUser.objects.all()
    serializer_class = SaleUserSerializer

    def create(self, request, *args, **kwargs):
        data = request.data.get("items") if 'items' in request.data else request.data
        many = isinstance(data, list)
        print (data, many)
        serializer = self.get_serializer(data=data, many=many)
        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)
