我正在关注使用 Rails 进行敏捷 Web 开发（rails 3.2+），我在第 16 章，关于部署。但是，我计划使用 Heroku 的大部分 b/c 都跳过了它，我目前正在尝试解决这个问题。无论如何，我昨天成功地解散了我的应用程序，它运行良好，除了我的一个模型。我的“订单”模型总是返回“我们很抱歉，但出了点问题”。错误，我不知道为什么。这是'heroku日志'

如您所见，有一个 500 内部服务器错误。但是，我不知道是什么原因造成的。我所有的其他模型都工作得很好。这不像我添加了“订单”模型而忘记了迁移。我知道“订单”表正在工作，因为我安装了一个 sql 控制台，我可以看到所有正在记录的条目。此外，它在本地工作得很好。我也这样做是为了查看更多错误报告：

config.consider_all_requests_local       = true

但是，我没有得到比“heroku 日志”中更多的信息。任何和所有输入将不胜感激。

订单控制器代码：

我认为问题出在您的邮件程序上，请尝试使用 sendgrid

我在您的错误日志中注意到您正在发送电子邮件，这可能会导致问题。Heroku 不会为您发送电子邮件，因此您需要使用 gmail 或获取附加组件。

Heroku 电子邮件参考：https ://devcenter.heroku.com/articles/smtp
