Absolute image URL?

rubyonrails-talk

I'm generating an XML feed to be used from outside of a Rails application. The feed should include URLs for associated images. I'm using image_path to generate the image URLs. This respects relative_url_root, but all it gives me is the absolute path of the image relative to the domain root (e.g. /image_assets/1234/ my_image.jpg). Is there a standard way to get fully specified absolute URLs to images? I looked at url_for, which implements an :only_path option, but that option is only available for controller paths.

Thanks,

Sven

Try image_url rather than image_path

Sadly that method does not seem to exist (at least not in ActionView::Helpers::AssetTagHelper or in the Rails API docs). I wish it did!

So write one! (or try this untested one)

def image_url(source)    abs_path = image_path(source)    unless abs_path =~ /\Ahttp/      abs_path = "http#{'s' if https?}://#{host_with_port}/#{abs_path}"    end    abs_path end

Put it in a helper such as app/helpers/application_helper.rb
