[Radiant] Checking for an asset existence

[Sean Cribbs]

How about this:

The Radius code:

<r:if_public_file_exists path="/images/home-highlight.jpg">
  <img src="/images/home-highlight.jpg" />
</r:if_public_file_exists>


The tag definition:

tag "if_public_file_exists" do |tag|
  tag.expand if File.exists?(File.expand(File.join(RAILS_ROOT, "public",
tag.attr['path'])))
end

Of course you could change the nomenclature however you like, and a few unit
tests wouldn't hurt, but that's the basic outline.
