Attach Cloudinary image to Rails model using ActiveStorage

I have a user model

class User < ApplicationRecord
  has_one_attached :photo
end

I'm trying to:

Here is what I think should work

user_img_response = Cloudinary::Uploader.upload("https://www.formula1.com/content/dam/fom-website/manual/Misc/2019-Races/Monaco2019/Monaco%20chicane%20HAM%20VER%20sized.jpg.transform/9col/image.jpg")

img_id = user_img_response["url"].match(/image\/upload.*/)[0]
signature = "#{img_id}##{user_img_response["signature"]}"

preloaded_file = Cloudinary::PreloadedFile.new(signature)
user = User.new(title: "Chris")
user.photo = preloaded_file

user.save
=> true

However, the photo is not being attached to the user instance

user.photo.attached? 
=> false

Assuming your app/models/photo.rb looks similar to this:

class Photo < ActiveRecord::Base
  attr_accessible :title, :bytes, :image, :image_cache

  belongs_to :album

  mount_uploader :image, ImageUploader

  validates_presence_of :title, :image
end

What happens if you try:

...
user = User.new(title: "Chris")
user.photo.image = preloaded_file # <---- assign file to image attribute
user.save

You can also try to emulate this sample app for your case: https://github.com/cloudinary/cloudinary_gem/tree/master/samples/photo_album

EDIT: you can try something like this:

require 'uri'

file = URI.open(user_img_response["url"]) # use cloudinary url
photo.image.attach(io: file, filename: 'image.jpg')
