• 修改Devise,以检查登记许可?
原标题:Modify Devise to check for permission to register?

我有<代码>Permission model and permissions table with an email field。 现有的用户(User model)可增加其希望邀请查看其信息的人的电子邮件地址。 这些电子邮件地址储存在数据库<代码>permissions.email现场。

我如何修改发展登记程序,以便它只允许在<代码>permissions表格中填写电子邮件地址的人创建账户?

最佳回答

此前曾与用户模型的验证人进行过协商。

validates :email, :my_access_control => true

从而产生类似情况

class MyAccessControlValidator < ActiveModel::EachValidator
  def validate_each(object, attribute, value)
    if ... not in permissions table.. 
      ... add to objects error collection why they cannot register
    end
  end
end
