使用设计时注册时禁用密码确认 [英] disable password confirmation during registration when using devise

问题描述

我正在使用Devise for Rails。在默认注册过程中，Devise要求用户输入密码两次进行验证和验证。如何禁用它？

感谢所有。 ：）

解决方案

我有点迟到这个聚会，但刚刚在我的头上碰到同样的问题最后一个小时左右，我以为我会分享我找到的最简单的解决方案：，您可以从注册表单中删除 password_confirmation 字段。 >这无法完全确认密码！

---

其原因在于 lib /devise/models/validatable.rb 在Devise源中：

 模块设计
模块模型
模块可验证
 
 
 def self.included（base）
 
 base.class_eval do 
＃.... SNIP。 .. 
 validates_confirmation_of：password，：if => ：要求输入密码？ 
 end 
 end 
 
＃... SNIP ... 
 
 def password_required？ 
！坚持？ || ！password.nil？ || ！password_confirmation.nil？ 
 end 
 end 
 end 
 end 
  

注意如果 password_required？返回 true 和 password_required？ password_confirmation 字段为 nil 将返回 false C>。

由于表单中存在 password_confirmation 字段，因此它将始终包含在参数哈希中，如一个空字符串，如果它留空，则验证被触发。但是，如果您从表单中删除输入，参数中的 password_confirmation 将为 nil ，因此验证不会被触发。

希望这是有用的！

谢谢，

I am using Devise for Rails. In the default registration process, Devise requires users to type the password twice for validation and authentication. How can I disable it?

Thanks all. :)

解决方案

I'm a little late to this party, but having just been scratching my head over the same problem for the last hour or so, I thought I'd share the easiest solution I've found: you can simply remove the password_confirmation field from the registration form, which disables the need to confirm the password entirely!

The reason for this lies in lib/devise/models/validatable.rb in the Devise source:

module Devise
  module Models
    module Validatable


      def self.included(base)

        base.class_eval do
          #....SNIP...
          validates_confirmation_of :password, :if => :password_required?
        end
      end

      #...SNIP...

      def password_required?
        !persisted? || !password.nil? || !password_confirmation.nil?
      end
    end
  end
end

Note that the validation is only triggered if password_required? returns true, and password_required? will return false if the password_confirmation field is nil.

Because where the password_confirmation field is present in the form, it will always be included in the parameters hash , as an empty string if it is left blank, the validation is triggered. However, if you remove the input from the form, the password_confirmation in the params will be nil, and therefore the validation will not be triggered.

Hope this is useful!

Thanks,
