Did you ever wanted to generate a <link rel="shortcut icon" href="/favicon.ico" /> tag with an helper to take advange of Rails’asset hosts, that is <link rel="shortcut icon" href="http://static.yourserver.com/favicon.ico" /> ? You’re only three easy steps away from it.
1. Add this code to lib/asset_tag_helper_ext.rb
module ActionView module Helpers module AssetTagHelper def link_tag(url_options = {}, tag_options = {}) href = url_options.is_a?(Hash) ? url_for(url_options.merge( :only_path => false)) : url_options tag( "link", "rel" => tag_options[:rel] || nil, "type" => tag_options[:type] || nil, "title" => tag_options[:title] || nil, "href" => compute_public_path(href, "", "") ) end end end end
2. Require it at the end of config/environment.rb as
require "asset_tag_helper_ext"
3. Add <%= link_tag("/favicon.ico", :rel => "shortcut icon") %> to your layout. Done!
This code has been tested with Rails 2.0.2 and Rails 2.3.2.
