通過mongo db獲取rails在heroku上的工作

Question

嗨，大家好像標題解釋我已經從git：//github.com/barmstrong/ribbot.git下載了一個開源代碼ribbot。我是ruby和rails的新手，但是我設置了自己的環境，並且能夠讓我的代碼在本地機器上運行。我想使用heroku作爲我的服務器基礎解決方案。我繼續推動這個應用程序heroku。 Heroku似乎告訴我，該應用程序運行正常，但我一直通過開源代碼重定向到一個錯誤頁面，但它並沒有在我的本地機器上這樣做。我懷疑這與mongo有關，我已經下載了MongoHQ for heroku的補充，並且仍然遇到了這個問題。我知道，此代碼使用mongoid

Answer 1

如果您已經安裝了MongoHQ附加在Heroku上，它創建您的Rails應用程序可用於連接到數據庫的MONGOHQ_URL環境變量。看起來你的config/mongoid.yml配置不正確。下面是Heroku的& MongoHQ工作示例：

development: 
    host: localhost 
    database: yourapp_dev 

test: 
    host: localhost 
    database: yourapp_test 

# set these environment variables on your prod server 
production: 
    uri: <%= ENV['MONGOHQ_URL'] %> 

希望這有助於！
