Making custom slugs

[volkanunsal]

I'm trying to create a custom slug using the instructions in the slug.rb. Here is my attempt:

 slug :title do |doc|
   doc._id[0..5]+"/"+doc.title.sub(/\s+/,'-')
 end

But this doesn't seem to be working. Not even debugger is stopping the flow inside the block that is passed to it. Can you shed some light on what needs to be done here, and what I'm doing wrong. Thanks.
