当我要在url中传递列表对象时，出现此错误

Got AttributeError when attempting to get a value for field `product` on serializer `ProductForParameterSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `int` instance.
Original exception text was: 'int' object has no attribute 'product'.

`

class ProductParameter(models.Model):
    product_attribute = models.ForeignKey(ProductAttribute,on_delete=models.CASCADE)
    product = models.ForeignKey(Product,on_delete=models.CASCADE,related_name='product_parameters')
    parameter = models.CharField(max_length=100,default='-')

和 serializers.py 看起来像这样

class ProductForParameterSerializer(serializers.ModelSerializer):
    name = serializers.CharField(source='product.name',max_length=255,read_only=True)
    product_desc = serializers.CharField(source='product.description',read_only=True)
    image = serializers.ImageField(source='product.image',read_only=True)
    price = serializers.DecimalField(source='product.price',max_digits=10,decimal_places=2,read_only=True)
    rating = serializers.CharField(source='product.rating',max_length=10,read_only=True)

    class Meta:
        model = ProductParameter
        fields = ('id','product','name','price','product_desc','image','rating')

您可以在模型中看到产品 ForeignKey。在此模型中，可能有多个产品，并且从此表中我应该获得ID唯一的产品。我不需要重复的产品。为此，我正在使用此视图

class ProductForParameterView(generics.ListAPIView):
    serializer_class = ProductForParameterSerializer

    def get_queryset(self):
        query_params = self.request.query_params
        products = query_params.get('product',None)

        productParams = []

        if products is not None:
            for product in products.split('|'):
                productParams.append(int(product))

        if products is not None:
            queryset = ProductParameter.objects.all()
            queryset = queryset.filter(product_id__in=productParams)
            qs = queryset.values_list('product',flat=True).distinct()
            return qs

但是我遇到错误。我怎样才能解决这个问题？预先感谢！
