我在本地机器上创建了两个开发环境，并在 heroku 上登台。

这是我的'mongoid.yml'：

development:
  sessions:
    default:
      database: mydb_development
      hosts:
        - localhost:27017
staging:
  sessions:
    default:
      database: mydb_staging
      uri: <%= ENV['MONGOLAB_URI'] %>

Mongoid 在本地机器上正常工作，但在 heroku 部署后，我出现下一个错误：

/app/vendor/bundle/ruby/1.9.1/gems/mongoid-3.0.14/lib/mongoid/config/validators/session.rb:81:in `validate_session_uri':  (Mongoid::Errors::MixedSessionConfiguration)
2012-12-25T10:12:44+00:00 app[web.1]: Problem:
2012-12-25T10:12:44+00:00 app[web.1]:   Both uri and standard configuration options defined for session: 'default'.
2012-12-25T10:12:44+00:00 app[web.1]: Summary:
2012-12-25T10:12:44+00:00 app[web.1]:   Instead of simply giving uri or standard options a preference order, Mongoid assumes that you have made a mistake in your configuration and requires that you provide one or the other, but not both. The options that were provided were: {"database"=>"xxxxx_staging", "uri"=>"mongodb://xxxxx:xxxxx@xxxxx.mongolab.com:37587/xxxxxx"}.
2012-12-25T10:12:44+00:00 app[web.1]: Resolution:
2012-12-25T10:12:44+00:00 app[web.1]:   Provide either only a uri as configuration or only standard options.

什么短语“仅提供 uri 作为配置或仅提供标准选项”是什么意思？如何正确配置 mongoid 以进行开发和登台？

删除这一行：

database: mydb_staging

因为数据库名称存在于 URI 中。
