嗨，我有一个本地加载的locomotivecms的实例，这一切都完美正常，但是当我将文件推送到heroku时我得到了以下错误，我似乎无法确定导致应用重启的原因

答案 0 :(得分：1)
从外观上看，您的问题与您与mongodb的关联有关。我认为这可能就像确保你已经启动MongoDB service一样简单。请查看以下链接MongoDB Installation。取决于您所使用的操作系统将取决于您需要执行哪些命令。但我完全相信你应该看看并确保你已正确安装它并且服务正在运行，因为这是你问题的根源。
此外还发现你必须在Heroku中安装MongoHQ插件。这将创建一个MONGOHQ_URL ENV变量，该变量应该是您的应用程序用于连接数据库的变量。
添加MongoHQ的命令 - heroku addons:add mongohq
此外，您可能需要查看以下MongoDB - Ruby以确保正确设置database.yml。您将在突出显示 Mongoid 2.x 的部分下看到。根据您使用的版本将阻止您关注的设置，因为当您向下滚动时，会有一个 Mongoid 3.x 的部分。希望这可以帮助。
