使用 OpenProject 一个月中，团队逐渐开始做任务管理、缺陷管理和工时管理，接下来要将内部文档用 Wiki 管理。

问题描述

我试着在 Wiki 写了份 PRD，文中引用的图片是中文文件名，遇到了两个问题

• 引用处无法显示

• 点击文末的链接提示 500 系统错误

解决方案

根据错误提示，找到 app/models/attachement.rb 文件，确保 URI.parse 前使用 URI.escape 转义。

修改前代码

   def external_url     url = URI.parse file.download_url # returns a path if local     url if url.host   end

修改后代码

   def external_url     escaped_url = URI.escape file.download_url     url = URI.parse escaped_url # returns a path if local      url if url.host   end
