redmine上传文件报错问题解决

        一波刚平，一波又起。继之前redmine出现各种问题之后，这次出问题又找上了我。

       这次是无法上传文件及附件，界面上可以看到的报错信息是Internal Server Error。光凭这点信息无法找到解决方案。

       更进一步查找LOG，报错信息如下：

           通过各种度娘谷哥，查到解决方案如下。

         

          修改如下文件

     actionpack (3.2.6) lib/action_dispatch/http/mime_negotiation.rb

         将这句改为

     Array(Mime[parameters[:format]])

          这个

      Array.wrap(Mime[parameters[:format]])

          一切OK啦。
