＃<＃<class：0x007f03a6a21830>：0x0056430f1b8750>的未定义方法`attachments_path'

Question

你好，我使用axlsx制作带有导轨的图形，但是我遇到了问题。

我遇到此错误“，显示＃3行的/var/www/redmine-3.4.2/app/views/attachments/indicateur.html.erb：

＃<＃：0x0056430f1b8750>的未定义方法`attachments_path' 你的意思是？附件路径                attachments_path_url”

如果有人有主意，我就是接受者。谢谢

                  the controller(attachments_controller.rb
