Question

我正在尝试使用Rails中的Devise设置两步注册过程，并遵循此tutorial by Claudio Marai。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'
  .
  .
  .

我认为这是由于我:registrations => "registrations"中存在routes.rb file，如the tutorial的第一步所述。然后我尝试了两个替代方案，这两个方案都导致了同样的错首先，我从:registrations => "registrations"中删除了routes.rb file。当这不起作用时，我重新插入该行并在registrations_controller.rb目录中添加controllers，如下所示：

class RegistrationsController < Devise::RegistrationsController
end

我认为这两个选项会产生相同的效果 - 但是 - 无论如何我都试过了。

我得到的错误如下：

以上错误让我很困惑！

使用相同的表单，当我添加password和password_confirmation字段时，事情就会顺利进行 - 创建用户帐户并使用确认链接向用户发送确认电子邮件。< / p>

对此我感谢任何帮助 - 谢谢！我正在使用Ruby 1.9.3-p125和Rails 3.2.1

问题不在于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Devise生成的，那么架构包括：

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

导致ConstraintException的SQL包括这个（省略了可读性）：

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

因此，有些事情告诉您的数据库适配器设置encrypted_password = nil。

你应该能够绕过它，或者运行一个删除encrypted_password上的NOT NULL约束的迁移，或者像你一样做，传入encrypted_password，但只是确保它在第一步中是空的，但在第二步中出现。
