Rails - Sep 2010 - Views: comments for template and partial location in filesystem?

I''m looking for an extension (gem, plugin, whatever) that inserts 
comments like

<!-- begin partial app/views/things/_thing.html.erb --%>
...
<!-- end   partial app/views/things/_thing.html.erb --%>

around rendered templates (except in production env). A cursory search 
didn''t bring up anything, but I may have chosen the wrong terms. It 
doesn''t have to work for arbitrary template engines, ERB is enough.

You want Frederick Cheung''s Tattler: http://github.com/fcheung/tattler
.
I think it will work with any template engine; certainly I''m using it 
with Haml.  I don''t know if it works with Rails 3 yet.

Tattler doesn''t work with Rails 3 anymore. This little bit of code, 
inspired by it, does.

unless Rails.env.production?
  class ActionView::Template
    def render_with_comment(*args, &block)
      render_result = render_without_comment(*args, &block)
      if mime_type.nil? || mime_type === [Mime::HTML, Mime::XML]
        ("<!-- TEMPLATE: #{identifier} -->\n" +
         render_result +
         "\n<!-- ENDTEMPLATE: #{identifier} -->"
        ).html_safe
      else
        render_result
      end
    end
    alias_method_chain :render, :comment
  end
end
