rails 3 + devise：如果注册表单有错误，如何防止在其他字段中擦除数据？ [英] rails 3 + devise: if registration form has error, how prevent from erasing data in other fields?

问题描述

我的设计注册表中有一个自定义字段（referral_code）。还有一个自定义注册控制器（所以我可以在注册后重定向到一个自定义的检查你的邮箱页面。）

I have a custom field (referral_code) in my devise registration form. Also have a custom registration controller (so I can redirect to a custom "check your email" page after they register).

除非新用户错误信息（如密码/确认不匹配）显示错误信息时也会擦除引用代码字段。

It all works fine except if the new user makes a mistake (such as password/confirmation not matching) when the error message is displayed it also erases the referral code field.

如何获取有效数据（引用代码）另一个字段（密码或电子邮件）会向用户发回一个错误消息，留下填写？

How can I have valid data (referral code) stay "filled in" when another field (password or email) throws an error message back to the user?

推荐答案

将其添加为virtual_attribute。实际上，即使通过验证，您的自定义字段也不会被保存，您将会更加困惑。

You need to add this as a virtual_attribute. Actually, even if it passed the validation your custom field would not have saved and you would have been even more confused.

这是一个正常的设计帐户模型：

Here is a normal devise account model:

class Account < ActiveRecord::Base

    devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable

    attr_accessible :email, :password, :password_confirmation, :remember_me

end

现在要获得自定义字段来保存，需要添加它们作为虚拟属性。

Now to get custom fields to save you need to add them as virtual attributes.

class Account < ActiveRecord::Base

    devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable

    attr_accessible :email, :password, :password_confirmation, :remember_me, :phone_number, :other_field

end

现在：phone_number，：other_field 将保存。
