Heroku 中 mongoid 的奇怪异常

Posted 2023-03-13

【中文标题】Heroku 中 mongoid 的奇怪异常

【英文标题】：Odd exception with mongoid at Heroku

【发布时间】：2012-12-26 23:15:42

【问题描述】：

我不断收到 heroku 错误。这是一个使用 Mongoid 的 Sinatra 应用程序。虽然我也在那里托管了一个 Rails 应用程序，但它不会导致任何错误，尽管它们具有完全相同的 mongoid.yml 文件。

这里是来自 heroku 的显示异常的日志

【问题讨论】：

那么...有什么例外？

在原木上掠夺，就是这样。

尝试总结日志。将几行日志条目粘贴到 *** 中的一个问题上，基本上说这是我的问题，解决它”是一种非常快速的投票方式

这里的问题是 ruby​​ 异常日志是堆叠的，因此实际错误位于顶部，并且基本上之后的每一行都是标准调用堆栈跟踪。换句话说，您粘贴的日志为我们提供了除有趣的日志之外的所有详细信息。

@AustinMullins，日志顶部不是您要查找的内容吗？

【参考方案1】：

错误是应用无法连接到它期望运行的本地 mongo 实例。

如果你认为日志信息很长，你还没有看到 Java Spring 自动装配异常 =) 虽然在这种情况下，最上面的错误信息足以确定问题。

我刚刚让 Mongo HQ 在 Heroku 上使用我的 Rails 应用程序，所以我的建议是：

在您的项目目录中运行 heroku config 以检查您是否已定义 RACK_ENV=production 并且 MONGOHQ_URL 已由 Heroku 定义。

如果 MONGOHQ_URL 没有在 Heroku 上定义为环境变量，很可能你还没有运行 heroku addons:add mongohq:sandbox 来告诉 Heroku 你想要一个 Mongo HQ 实例。

如果未定义 RACK_ENV=production，只需添加： heroku config:add RACK_ENV=production

在此之后，使用 heroku restart 重新启动您的应用程序，它应该可以工作了。

Rails 应用程序（而不是 Sinatra）的仅供参考，RACK_ENV 变为 RAILS_ENV。
