Question

我有型号产品：

class Product(models.Model):
    ...
    image = models.ImageField(
        upload_to=lambda instance, filename: 'images/{0}/{1}'.format(instance.id, filename),
        max_length=254, blank=True, null=True
    )
    ...

然后我有序列化器：

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = (
            ...
            'image',
            ...
        )

然后我有意见：

class ProductViewSet(BaseViewSet, viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    @detail_route(methods=['POST'])

    def upload_image(self, request, *args, **kwargs):
        upload = request.data['file']
        print(upload.name)
        product = self.get_object()
        product.image.delete()

        upload = request.data['file']
        product.image.save(upload.name, upload)

        return Response({'Location': product.image.url}, status=status.HTTP_201_CREATED)

问题仅出在图像上。在浏览器黑色窗口中上传图片更改'源代码'，我无法打开它。 Mp3和PDF格式工作正常。为什么会这样？谢谢。

也许问题出在base64图片上？在这种情况下，您应该从drf_base64.serializers导入ModelSerializer并从中继承。

Django REST Framework，上传时的图像中断
