在使用Heroku時在滑軌控制檯中的雙查詢

我注意到，在Heroku中使用滑軌控制檯時我有雙重查詢。我之前沒有看到這個問題。任何想法可能導致它？在使用Heroku時在滑軌控制檯中的雙查詢

我已經閱讀this topic，但它沒有解決我的問題。

您是否在rails_stdout_logging GitHub倉庫中看到過[此問題]（https://github.com/heroku/rails_stdout_logging/issues/1）？ – pdoherty926

是的。我做了，但我沒有找到解決方案，我的軌道控制檯問題。 –

在評論這基本上有一個答案已經here Heroku的問題頁面上引用。

但只是總結它：

兩個SQL查詢並沒有實際發生。這只是記錄器打印兩行的問題。

除去重複信息的方式是該行添加到Procfile（它告訴Heroku上如何運行的應用程序的文件）：

web: rackup -p $PORT

這使得應用程序開始rackup而不是rails server。

如果這不起作用，請參閱問題主題以獲取更多建議。

我在應用程序的根目錄下創建了名爲'Procfile'的文件。它沒有幫助。 –
