验证具体的电子邮件特定域设计3轨道上的红宝石4 [英] Validation specific email specific domain devise 3 ruby on rails 4

问题描述

我以前发布了一个关于如何使用验证的问题，只允许访问者使用以@ grenoble-em.com结尾的电子邮件地址在我的网站上注册。我使用的是设计3和Rails 4.我是相当新的，会感谢任何答案。这是我的用户模型。

I previously posted a question about how to use validations to only allow visitor using an email address ending with @grenoble-em.com to be able to register on my website. I am using devise 3 and Rails 4. I am fairly new to it and would appreciate any answer. Here is my user model.

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_attached_file :picture, :styles => { :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/images/:style/missing.png"
  validates_attachment_content_type :picture, :content_type => /\Aimage\/.*\Z/
  validates :email, uniqueness: true
end

提前谢谢大家。你们做一个伟大的工作帮助人们:)

Thank you all in advance. You guys do a great job helping people :)

推荐答案

如果你只想验证电子邮件包含该域，而不是其他的，你可以添加这个验证器：

If you simply want to validate that the email contains that domain, and not much else, you can add this validator:

class User < ActiveRecord::Base
  validates_format_of :email, with: /\@grenoble-em\.com/, message: 'You should have an email from grenoble-em.com'
end

您可以在这里阅读有关所有验证器的更多信息： http://api.rubyonrails.org/classes/ActiveModel/Validations/HelperMethods.html
