Question

我试图在heroku中部署我的应用程序。我的应用程序使用mongohq作为数据库。我已将相应的附加组件添加到我的应用中。

部署应用程序时出现此错误。

Cleaning up the bundler cache.

   ** Notice: The native BSON extension was not loaded. **
   For optimal performance, use of the BSON extension is recommended.
   To enable the extension make sure ENV['BSON_EXT_DISABLED'] is not set
   and run the following command:
   gem install bson_ext
   If you continue to receive this message after installing, make sure that
   the bson_ext gem is in your load path.

看起来试图在database.yml中编写DATABASE_URL，但我没有使用它。我只是使用monogoid.yml并设置正确的ENV var MONGOHQ_URL。

我是否需要设置任何配置，以便heroku可以检测到我使用mongo作为我的数据库？

编辑：

我的mongoid.yml文件看起来像这样。

production:
    sessions:
     default:
      uri: <%= ENV['MONGOHQ_URL'] %>

我读过那篇文章，我正在遵循这些步骤。

如果有人经历过相同的事情，我在我的应用程序中.rb是对我需要带走的活动记录的引用：

#require "active_record/railtie"

另外，请仔细检查您的环境文件，在某些情况下，您可能会有一些active_record配置代码。

希望它有所帮助。

Heroku与mongohq无效的database_url
