Rails Gem Devise是否有解决方案允许用户拥有多个电子邮件？ [英] Is there a solution for Rails Gem Devise to allow a user to have multiple emails?

问题描述

我正在寻找一个解决方案，让我的应用上的用户拥有超过1封电子邮件。这应该类似于Facebook，LinkedIn和Quora。帐户可以有多个电子邮件，1个作为主要邮件。

I'm looking for a solution to allow a user on my app to have more than 1 email. This should work similar to Facebook, LinkedIn and Quora. Where an account can have multiple emails, 1 as the primary.

有没有一个交钥匙解决方案的设计avaialble？我希望不要从头开始写这个，因为它很常见。

Is there a turn-key solution for devise avaialble? I'm hoping to not have to write this from scratch given it's so common.

想法？谢谢

推荐答案

嗯...我建议创建新的模型，你会做这样的事情：

Hm...I'll suggest to create new model, You'll do something like this:

例如，模型将是 UserEmail 。

class UserEmail < ActiveRecord::Base
    belongs_to :user
end

class User < ActiveRecord::Base
    has_many :user_emails
end

并覆盖devise的方法在中找到记录用户模型：

and override devise's method to find record in User model:

def self.find_first_by_auth_conditions(warden_conditions)
  conditions = warden_conditions.dup
  if email = conditions.delete(:email)
    User.includes(:user_emails).where('user_emails.email = ?', email).first
  else
    super(warden_conditions)
  end
