我正在尝试使用 Rails 中的 Devise 设置两步注册流程，并遵循Claudio Marai 的本教程。当我在表单中输入电子邮件地址时（第一步），我收到一条错误消息，告诉我存在路由错误并且找不到RegistrationsController

Started POST "/users" for 127.0.0.1 at 2012-05-03 22:50:59 -0400

ActionController::RoutingError (uninitialized constant RegistrationsController):
  activesupport (3.2.1) lib/active_support/inflector/methods.rb:229:in `block in constantize'
  activesupport (3.2.1) lib/active_support/inflector/methods.rb:228:in `each'
  activesupport (3.2.1) lib/active_support/inflector/methods.rb:228:in `constantize'
  .
  .
  .

我认为这是由于本教程第一步中描述的:registrations => "registrations"我的存在。然后我尝试了两种替代方法，它们都导致了相同的错误。首先，我从. 当这不起作用时，我重新插入该行并将 a 添加到如下所示的目录中：routes.rb file:registrations => "registrations"routes.rb fileregistrations_controller.rbcontrollers

class RegistrationsController < Devise::RegistrationsController
end

我认为这两个选项会产生相同的效果 - 但是 - 我还是尝试了它们。

我得到的错误如下：

上面的错误让我很困惑！

使用相同的表单，当我添加password和password_confirmation字段时，事情会顺利进行 - 创建用户帐户，并通过确认链接向用户发送确认电子邮件。

我将不胜感激有关此的任何帮助-谢谢！我正在使用Ruby 1.9.3-p125和Rails 3.2.1

问题不是由于 Rails 验证，而是由于违反了数据库约束。

很可能，如果您的用户表迁移是由设计生成的，那么架构包括以下内容：

"encrypted_password" varchar(128) DEFAULT '' NOT NULL

导致 ConstraintException 的 SQL 包括以下内容（为便于阅读而省略）：

SQL (14.0ms)  INSERT INTO "users" (..., "encrypted_password", ...) VALUES (..., ?, ...)  [..., ["encrypted_password", nil], ...]

所以，有些东西告诉你的数据库适配器设置encrypted_password = nil.

您应该能够规避它，或者运行一个删除 上的 NOT NULL 约束的迁移encrypted_password，或者按照您所做的那样，传入一个encrypted_password，但只需确保它在第一步中为空，但在第二步中存在.
