Rails ActiveStorage将图像文件从React Native客户端上传到Cloudinary

Question

如何使用ActiveStorage和Cloudinary将图像附加到模型上？我一直在尝试在UserType.rb文件中遵循以下方法。

class Hash < Types::BaseInputObject
  argument :_parts, [String], required: false
end

argument :image, Hash, required: false
argument :image_name, String, required: false


decoded_image = Base64.decode64(image)
image_io = StringIO.new(decoded_image)

@user.image.attach(io: image, filename: 'test')
@user.save

从客户那里得到的照片赞美了

 "variables"=>{"image"=>{"_parts"=>[["image", {"image"=>"file:///Users/hugohouyez/Library/Developer/CoreSimulator/Devices/B25284C3-EE82-4DD3-AF6D-309F8CA7C608/data/Containers/Data/Application/C5AB683D-EAA5-482B-B52E-60D98B6753CE/Documents/images/79AD6A23-CDF9-451D-AC6B-ED3FE045336E.jpg"

但是，我无法使其正常运行。我收到以下错误消息：

  

错误：GraphQL错误：为_parts.0提供了Hash类型的变量图像无效值（无法强制转换值[“ image”，“ {\” image \“ => \” file：...

在客户端上，代码看起来像这样

const [createUser] = useMutation(CREATE_USER);

const createUserHook = ({image, image_name, first_name}) => {
let fileType = image[image.length - 1];
let formData = new FormData();
formData.append('image', {
  image,
  name: `photo.${fileType}`,
  type: `image/${fileType}`,
});
return createUser({ variables: { image: formData, image_name: image_name, first_name: first_name }})
}

感谢您的帮助，因为我找不到任何官方文档。
