我最近分叉了https://github.com/fortuity/rails3-mongoid-omniauth並試圖在heroku.com上運行。這是一個應用程序,演示如何在heroku上使用MongoDB(通過MongoHQ)以及OAuth身份驗證。我分叉的代碼快照是https://github.com/jgodse/rails3-mongoid-omniauth/tree/8cb490e660ab1d2d1df0f68312584563f0fd223aHeroku:MongoHQ:連接問題
當我調整了mongoid.yml以包含URI參數後,刪除其他參數爲生產(即heroku)環境,然後在heroku.com上啓動應用程序,我得到以下日誌來自heroku日誌)。

我的Heroku的環境看起來像這樣(有一些關鍵的信息xxxx'ed出):

Heroku的日誌說,它仍在試圖連接到本地主機:27017即使我刪除本地主機引用從mongoid.yml。還有什麼我必須做的強制它連接到我的MONGOHQ_URL?
