How to save an image from a url with rails active storage?

Question

I\'m looking to save a file (in this case an image) located on another http web server using rails 5.2 active storage.

I have an object with a string parameter for s

Answer 1

The simplest way to do this without having to enter filename explicitly is:

url = URI.parse("https://your-url.com/abc.mp3")
filename = File.basename(url.path)
file = URI.open(url)
user = User.first
user.avatar.attach(io: file, filename: filename)

This automatically saves the avatar against that particular user object.

In case you are using a remote service like S3 the URL can be retrieved by:

user.avatar.service_url
