How to attach image from the url in Rails Active Storage

Question

I want to attach an image to a record in the rake task. The only thing I have for image is the URL. This is the URL for the image https://cdn.iconscout.com/icon/free/png-256/google-analytics-7-722699.png.

I used this approach from a StackOverflow answer.

require 'open-uri'
downloaded_file = open(tool.image)
new_tool.image.attach(io: downloaded_file, filename: "foo.png")

This gives the following error.

ActiveStorage::IntegrityError: Unsupported source URL: #<StringIO:0x00007f9bd9759f28>
Caused by:
CloudinaryException: Unsupported source URL: #<StringIO:0x00007f9bd9759f28>

Could someone help me out?

In this case, I think that you should pass a string containing the image's URL to open:

require 'open-uri'

image_url = "https://cdn.iconscout.com/icon/free/png-256/google-analytics-7-722699.png"    
downloaded_file = open(image_url)

new_tool.image.attach(io: downloaded_file, filename: "foo.png")

Thanks for replying. In my question, tool.image is a URL of an image. – Salman Haseeb Sheikh May 18 '20 at 08:20
@SalmanHaseebSheikh What are the versions of Ruby and Rails that you are using? – pedrosfdcarneiro May 18 '20 at 15:13
Ruby 2.7.0 and Rails 6.0.2. – Salman Haseeb Sheikh May 18 '20 at 15:38
Are you sure that `tool.image` returns a String? Can you put here the output for `tool.image.class`? – pedrosfdcarneiro May 18 '20 at 15:46
Latest versions of ruby suggest using `URI.open` instead: warning: calling URI.open via Kernel#open is deprecated, call URI.open directly or use URI#open – soundly_typed Aug 13 '20 at 01:30
