django3.2.6 异常，实在不知道啥原因了，求解，如何解决？

Question

问题是出在这行：
        
**product = product_serializers.save()**

```python
class productAddAPIView(APIView):
    def post(self, request):
        product_serializers = productModelSerializers(data=request.data)
        if product_serializers.is_valid(raise_exception=True):
            product_info = product_serializers.save()
            return ApiResponse(results=product_info )

```python
class product(models.Model):
    product_name = models.CharField(max_length=50, verbose_name='产品名称')

    class Meta:
        db_table = "product"

class productModelSerializers(serializers.ModelSerializer):
    class Meta:
        model = product
        fields = '__all__'

调用接口后报错：

class productAddAPIView(APIView):
    def post(self, request):
        product_serializers = productModelSerializers(data=request.data)
        if product_serializers.is_valid(raise_exception=True):
            try:
                # 如果你想返回操作状态,加上判断报错,报错即未成功,为报错即成功,字典中还可以加上其他数据
                # save()后会返回一个model对象,对象是不能够json序列化的,所以不能直接使用save返回的对象当做json返回前端
                product_serializers.save()
                
                product_info = {"code":"200","data":"操作成功"}
            except Exception as e:
                product_info = {"code": "2001","data":f"操作失败{e}"}

            return ApiResponse(results=product_info )
