How to download a picture in Rails and attach to model?

Question

I have a model with has_one_attached :picture.

I implemented a method which should download the picture for the object

  def load_picture
    RestClient.get(url, :accept => 'image/jpg')
  end

(url attribute is working, i.e. tested by opening in a browser, it is downloading the picture)

Trying RestClient Gem here but any other solution would work too.

After the download I try to attach with

MyModel.picture.attach(load_picture)

...but it fails. Probaly because the attachment is nil.

My question: How to download the image using a simple get request? Do I have to call something like .attachment on the response?

Try this:

YourModel.picture.attach(
  io: RestClient.get(url, :accept => 'image/jpg'),
  filename: 'IMAGE_NAME.jpg',
  content_type: 'image/jpg'
)
