Aer*_*iel 3 ruby-on-rails heroku devise
我正在尝试在 Heroku 上进行设计工作。它在我的计算机上运行良好，但是当我在 Heroku 上推送我的代码时，每次尝试创建用户时我都会收到此错误：`我们很抱歉，但出了点问题。
如果您是应用程序所有者，请查看日志以获取更多信息。`。我检查了日志a，没有错误。他们来了 ：

有什么猜想吗？

Any guess?
我想错误是你没有在 Heroku 上迁移你的数据库。
假设您的开发环境“只是”您的 Rails 应用程序，这是一个常见的问题——不仅如此。您必须确保您的生产数据库也填充了您在 Rails 数据库中拥有的相同数据
我会确保你已经这样做了：
$ heroku run rake db:migrate
——
调试
在 Heroku 上“调试”的一个偷偷摸摸的技巧是让你的应用程序在“开发”模式下运行。尽管您必须确保之后将其切换回生产模式，但如果您执行以下操作，它将正确显示错误：
#config/environments/production.rb
config.consider_all_requests_local = true # false
更改此设置，重新推送到 Heroku，然后您将能够在屏幕上看到错误的详细版本。我想它会说你的数据库中没有正确的列;)
