Zipping files contained in a dir (rubyzip)

hey so I'm trying to zip all the files contained in a directory (RubyZip). heres what I have:

      def bundle            #create the ZIPfile with the title of (:id).zip       bundle_filename = "public/attachments/#{self.id}/#{self.id}.zip"

           #open the ZIPfile in order to add items in       Zip::ZipFile.open(bundle_filename, Zip::ZipFile::CREATE) {        >zipfile>          Dir.foreach("public/attachments/#{self.id}") do |item|          t = File.open(item)          zipfile.add(t, "public/attachments/#{self.id}")          end        }

          #change permissions on ZIPfile        File.chmod(0644, bundle_filename)         self.save        end

This successfully executes the first line and creates the zip file with the correct name but it is not adding to the zip file all the files contained in that directory. Any Ideas?
