That doesn't make sense, you ask how to create an image object, then say that an image object is an object returned by nokogiri.  So to create it all you have to do is make that request to nokogiri.

Using  ActiveStorage but I'll look at the page thanks

I'm trying to insert an image into the assets table from web scraping Scraping gets me the src of the image I don't know if I should submit a form or do a raw insert in my script 

[Walter Lee Davis]

Read the documentation for your file upload package -- I believe you mentioned ActiveStorage -- about uploading from a URL. This is a common feature in many file attachment systems. CarrierWave, Shrine, CarrierWave, even Paperclip have a way to do this.

It usually amounts to something like

require 'open-uri'
file = open(remote_url).read
@your_instance.file = file
@your_instance.save # (the file should be persisted locally)

Thanks, I'll use Carrierwave because when I googled "ActiveStorage remote file upload" what I found was a discussion where someone says you can't do this in ActiveStorage but you can with Carrierwave

I'd recommend Shrine. Much better documentation, current development, and a super-responsive development team.

With 'require open-uri' i can just use ActiveStorage don't need to use a gem?   

[Walter Lee Davis]

Open-URI is part of the Ruby standard library, not a third-party Gem. If you are in a Rails app, you won't need to do this, because it's part of the requirements. But if you are building a stand-alone script for testing, as you should, you may need to do this before the Kernel.open command will open a URI.
