Ruby on rails錯誤繼續刷新瀏覽器

Question

我陷入了這個奇怪的問題。這個問題只在生產服務器上，在本地服務器上工作正常。

我檢查了我的生產日誌，發現錯誤是在行：

::的ActionView ::模板錯誤（未定義的方法`FULL_NAME」的零：NilClass）

但是，當我刷新瀏覽器錯誤消失，頁面正常加載。我不確定是什麼導致了錯誤。

這是我的日誌：

我使用設計用於管理用戶登錄和FULL_NAME設置爲訪問屬性在user.rb型號爲：

attr_accessible :full_name 

服務器環境用nginx，獨角獸，capistrano和mysql數據庫設置。任何幫助將不勝感激。提前致謝。

看起來像有某種服務器問題。我重新部署了應用程序，一切正常。
