我有一个似乎与这两个链接有关的错误：

请参阅下面的控制台日志。我正在使用 Mongoid/MongoHQ 运行，当我创建一个对象（显然是任何数据库对象）时，我得到这个“需要登录”错误。但是请注意，数据库对象已创建并在错误发生后位于数据库中。

有什么方法可以让我自己解决这个问题，或者可能是 MongoHQ 需要解决的问题？

我现在正在遇到一模一样的问题。这并不完全是一个解决方案，但您可以通过将 mongoid.yml 中的 'safe' 选项设置为 false 来解决该问题。它看起来类似于：

production:
  sessions:
    default:
      uri: <%= ENV['MONGOHQ_URL'] %>
      options:
        skip_version_check: true
        safe: false

事实证明，问题在于 MongoHQ 升级了他们的 MongoDB，并且引入了与 mongoid 的稳定分支不兼容的问题。

Chris Winslett 修复了这个 bug，然后 durran 把它拉进了 mongoid master。但是当我发布这个 stackoverflow 时，它并没有包含在 stable 分支中。

解决方案：

  • 我通过更新我的 gemfile 以从 github 中提取 mongoid 解决了这个问题。
  • durran 现在已将其包含在 stable-1.2.0 中，因此如果您gem update.
