Devise Registration不显示嵌套表单字段

Question

我在rails 5.2中使用devise，并尝试在nested fields中添加一些user signup。我正在尝试创建一个名为second registration path的quickstarts，用户可以在一个操作中注册并创建一个患者。我遵循了此线程Rails multiple registration paths with Devise

的答案

问题是nested fields没有显示在注册页面上，并且我无法弄清楚为什么它不起作用，所以将不胜感激。

Answer 1

这是错误的一般方法。 Devise::RegistrationsController是从头开始构建的，可以处理用户注册自己的情况。如果您正在尝试注册其他用户，那么您将不会从中获得任何帮助，因为您只是在与一个非常复杂的野兽战斗，以使其执行其并非为之准备的任务。

您实际上不必注册其他用户。您只需创建它们。

您正在做的实际上是Devise::Invitable设计的目的。它使您可以通过“邀请”其他用户记录来创建其他用户记录，然后发送电子邮件以使他们可以通过令牌声明其帐户。这样可以避免您被黑客入侵的解决方案带来的巨大问题，即创建记录的用户必须了解新患者密码，并以某种方式将该知识传递给他们正在注册的患者。
