如果您已经在Heroku中安装了MongoHQ插件，它将创建一个MongoHQ_URL环境变量，Rails应用程序可以使用该变量连接到数据库。看起来您的config/mongoid.yml配置不正确。以下是Heroku&MongoHQ的一个工作示例：

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'] %>

开发：
主机：本地主机
数据库：yourapp\u dev
测试：
主机：本地主机
数据库：yourapp\u测试
#在prod服务器上设置这些环境变量
制作：
uri:

希望这有帮助

我们可以查看您的

配置/mongoid.yml

？另外，您是否在Heroku上安装了任何Mongo加载项？您好，很抱歉回复太晚。是的，我添加了mongo add-onDevelopment:host:localhost数据库：ribbot_开发测试：host:localhost数据库：ribbot_测试产品：uri:这是否意味着我应该使用mongolab而不是mongoHQ？感谢您的回复。刚才看到我的mongoid.yml与urs非常相似，但我的mongoid.yml指定了mongoid.yml。这是否意味着我应该安装mongolab附加组件？这取决于您的Heroku应用程序正在使用什么以及您的首选项。使用CLI中的命令

heroku addons

检查应用程序上是否安装了任何一个插件。如果两者都没有，就随便挑一个用吧。在Rails配置中，环境变量的工作方式应该是相同的。
