因此，我通过载波上传图像并正确关联它们进行 Cloudinary 直接上传，但是一旦创建它们，我似乎无法更新或销毁它们。

更新时，图像被上传并可以通过我的仪表板获得，但是相关记录永远不会改变，我总是看到原始图像。

尝试销毁图像时出现错误：父模型和图像字段嵌套Couldn't find Image with ID=1 for Finish with ID=11在哪里。Finish此外，Image模式是多态的。我不确定为什么当隐藏输入的图像 ID 为 20 时它认为图像 ID 为“1”。

任何想法我做错了什么？

这是生成的表格（如果有任何其他有用的代码可以发布，请告诉我）：

事实证明，这根本不是 Cloudinary 问题。

1) 图像没有更新，因为我的(doh!)中没有updateordestroy方法images_controller

2）我收到Couldn't find Image with ID=1 for Finish with ID=11错误是因为我的 JS 标记了要删除的隐藏文件配置错误并更改了所有隐藏字段的值。虽然我不知道为什么它以前可以工作，因为它没有改变。
