我在class ItemViewSet(viewsets.ModelViewSet):
serializer_class = ItemSerializer
def get_queryset(self):
return Item.objects.filter(user=self.request.user)
中有一个简单的表，其中Oracle DB为整数（ID），PK为 BLOB 列，我可以存储{{ 1}}。
我已为该表创建了Web服务，当我通过ATTACHMENT消费时，它就是这样的。
image, audio, video, File..etc当我使用oracle移动应用程序时，总是会出现URL错误。以下是供您参考的错误日志
<List>
<attachment>
<attachment>oracle.sql.BLOB@27c59ba1</attachment>
<id>101</id>
</attachment>
</List>
