heroku db：推送問題

Question

我有一些問題得到db：推動與heroku一起工作。

正如我已經讀過的其他地方，有一個紅寶石版本> 1.9.3-p0的問題，所以我已降級到1.9.2-p290，因爲它似乎是最常見的建議。

這可以通過運行紅寶石-v並獲得ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.4.0]

是什麼原因造成這個問題和/或如何解決它確認？

Answer 1

不確定究竟是什麼修復了它，但我試圖通過本地種子文件推送。當我嘗試運行db：seed時，我不斷收到遷移錯誤。當我嘗試運行遷移時，出現遷移錯誤。所以我跑了以下內容：然後繼續運行分貝：遷移，因爲我有新的錯誤。

heroku run rake db:reset 
heroku run rake db:migrate 

Answer 2

我想這是由於持有人表的日期格式（字段是時區位移）。
