Question

I have been scraping sites and retrieving image information regarding them.

However, I need to have a http:// or http://www. or subdomain of the site to the image src if it doesn’t contain it.

Is there a quick function in rails that works on this?

Answer 1

You should try looking at Ruby itself and its string documentation, for example there is start_with? which checks if string starts with the input, you can use something like this:

domain = "http://domain.com/"
image = "image.jpg"

unless image.start_with?(domain)
  domain << image.url
end

You should be able to come up with a method to iterate over all your scraped images and update them.
