運行Heroku rake db：在Heroku上遷移不會遷移數據庫

因此當我運行heroku rake db：migrate後，推送我的最新代碼Heroku不會改變表格。但是，當我嘗試在我的電腦上（我也使用Postgresql）並運行rake db：migrate時，它會遷移數據庫並將必要的表和字段添加到現有表中。運行Heroku rake db：在Heroku上遷移不會遷移數據庫

但是，從heroku，我沒有得到任何錯誤，這是我得到的迴應。

從應用程序日誌輸出？它看起來像Rails正在反思表格。首先，我要確保數據庫尚未遷移。遷移後您是否重新啓動了您的Rails應用程序？如果應用程序在生產模式下運行，Rails可能會保留舊模式。另一種可能性是schema_information中的錯誤條目。我發現檢查這種事情的最簡單方法是使用輕敲將prod數據庫下載到本地數據庫。您也可以針對ActiveRecord :: Base.connection對象發出SQL命令以直接檢查prod數據庫。 – 2011-02-17 18:16:00

嘿，所以問題是（這是非常遲鈍的，我沒有想到這一點）我沒有重新啓動服務器。運行heroku重啓解決了這個問題。 – 2011-02-17 18:25:49

您需要使用「heroku restart」重新啓動heroku服務器。
