def upload
      @path = "#{RAILS_ROOT}/public/upload/"+remove_nil(params[:cesta])
      @io = params[:file]
      data = @io.read
      size = @io.size
      name = named_id(@io.original_filename)

      if @io.kind_of?(Tempfile)
        FileUtils.copy(@io.local_path, @path+name)
      else
        File.open(@path+name, "wb") { |f| f.write(@io.read) }
      end
  redirect_to :action => 'index', :cesta => remove_nil(params[:cesta])
  end

tohle mi ale pri prvnim pokusu o upload souboru hodi nasledujici chybu, kdyz pak zkusim uploadnout dalsi soubor, uz to jede normalne:

uninitialized constant Admin::UploadController::Tempfile
