redmine上傳檔案報錯問題解決

        一波剛平，一波又起。繼之前redmine出現各種問題之後，這次出問題又找上了我。

       這次是無法上傳檔案及附件，介面上可以看到的報錯資訊是Internal Server Error。光憑這點資訊無法找到解決方案。

       更進一步尋找LOG，報錯資訊如下：

           通過各種度娘穀哥，查到解決方案如下。

         

          修改如下檔案

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

         將這句改為

     Array(Mime[parameters[:format]])

          這個

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

          一切OK啦。
