ruby rails: uploaded file id

I am uploading a file as follows (snippet attached).  I would like to know whats the id(database column) of this uploaded file. Is there any way I can get it?

Thanks,
GT.
def save_attachment
    @program = @object
    @attachment = Attachment.new
	if request.post? && params[:attachment]
      @attachment = @program.attachments.build(params[:attachment])
      @attachment.name = @attachment.filename if @attachment.name.blank?
      result = false
      logger.silence do
        result = @attachment.save
      end
      
      if result
        update_event(@program.event)
	    flash[:notice] = "Upload successful"
        redirect_to :controller => :main, :action => :show_event, :id => @program.event
      end
	end
  end

if you want the id of the upload then it would be  @program.event_id  looking at your code.
