编辑：感谢@vinodadhikary - 经过进一步调查，似乎错误发生在 a）电子邮件不是唯一的，b）名称不是唯一的或 c）电子邮件显然是假的（h@h.com）。如果 Devise 不接受注册，我希望错误能够优雅地发生。如果密码不匹配或字段不完整，则错误处理是正确的。此外，非唯一名称应该不是问题吗？这是由使用 FriendlyID 创建 slug（使用名称作为 slug）引起的吗？

原文：当有人在满足上述注册条件之一时注册时，我在我的 Devise 注册中遇到了一个奇怪的错误。我认为我没有为 Devise 安装做任何超出正常范围的事情（使用 Rails Composer，如果重要的话）。在此先感谢您的帮助...

这是错误：

因此，FriendlyId 因某种未知原因而窒息创建某个 slug 的多次迭代（在 henry 和 henry--2 后卡住，henry--3 抛出错误）。我通过将 slug 属性更改为 email、运行 find_each(&:save) 来清除当前的 slug 并在将 slug 返回名称后执行相同操作来解决此问题。这解决了看起来的问题。

展望未来，我将切换到唯一的用户名，因为使用名称（不必是唯一的）太难看了。

感谢@bdares 和@vinodadhikary 的帮助
