Zipping files in a directory with RubyonRails
===

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 succesfully 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?
