我想通過玩框架應用程序在heroku上設置postgres數據庫，但我不斷收到有關我的DATABASE_URL的錯誤。Heroku - 無法通過Play Framework應用程序設置postgres數據庫？
堆棧跟蹤： - ：
echo "export DATABASE_URL=postgres://postgres:[email protected]/Play">>.bash_profile
. .bash_profile
我試圖設置另一個URL以及，我發現使用命令heroku config -

我使用下面的命令來設置我的DATABASE_URL作爲環境變量我所知道的是一個很長的postgres網址，但它並沒有起作用，每次都出現同樣的異常。
以下是我在application.conf文件添加
%prod.db=${DATABASE_URL}
依賴
val appDependencies = Seq(
"postgresql" % "postgresql" % "9.1-901.jdbc4"
)
所以現在我感到困惑的我DATABASE_URL。爲什麼heroku無法用合適的價值取代它。 heroku在哪裏尋找合適的URL？在我的application.conf文件中或在我係統的bash配置文件中設置的環境變量中？
任何幫助將非常感激。
感謝

你列出一個'DATABASE_URL'值，當你運行'的Heroku config'？ –
@RyanDaigle是的，我看到了。我試圖使用該網址，但沒有運氣。 – Varundroid
