Ruby on rails：Devise，想添加邀请码？ [英] Ruby on rails: Devise, want to add invite code?

问题描述

我想添加一个invite_code要求给用户注册。 IE浏览器。除了要求他们指定电子邮件/密码组合外，我还需要一个附加字段：invite_code。这是一个临时解决方案，以便非特定用户在给定的alpha时间段内无法登录。

由于Devise不添加控制器，我感到困惑。我很熟悉虚拟属性的概念，它使我觉得我可以在模型中添加一个：invite_code，然后只是硬编码一个步骤，现在它的邀请代码必须等于12345或现在的任何内容。 / p>

这是否符合设计认证？而且我应该如何从一个适当的轨道平静的方法来接近？

非常感谢。

解决方案

1）除了getter之外，虚拟属性通常需要一个setter。

最简单的方法是添加

  attr_accessor：invite_code 
 attr_accessible：invite_code＃allow invite_code通过质量分配设置
＃请参阅下面的James的评论。 
  

到用户模型

2）我认为Devise希望用户模型验证。所以你可以通过添加

  validates_each：invite_code，on => ：创建do | record，attr，value | 
 record.errors.add attr，请输入正确的邀请码，除非
 value&&值==12345
 end 
  

注意：添加：on =>：只有创建新用户才能使用invite_code，而不是进行更新。

I would like to add an invite_code requirement for users to sign up. Ie. in addition to requiring them to specify an email/password combo, I want an additional field :invite_code. This is a temporary fix so that non-wanted users cannot login during a given alpha period.

I'm confused since Devise doesn't add controllers. I'm sort of familiar with the concept of virtual attributes, and it strikes me that I could add a :invite_code to the model, and then just hard code a step now where it says invite code must equal 12345 or whatever for now.

Does this make sense with devise authentication? And how do I go approaching this from a proper rails restful approach?

Thank you very much.

解决方案

1) A virtual attribute usually needs a setter in addition to a getter.

Easiest way is to add

attr_accessor :invite_code
attr_accessible :invite_code # allow invite_code to be set via mass-assignment
    # See comment by James, below.

to the User model

2) I presume that Devise wants the User model to validate. So you could stop the validation by adding

validates_each :invite_code, :on => :create do |record, attr, value|
    record.errors.add attr, "Please enter correct invite code" unless
      value && value == "12345"
end

NOTE: added :on => :create since the invite_code is only needed for creating the new user, not for updating.
