Question

我在rails 3.2.13中使用attr_encrypted来加密列。为此，在我的模型中，我有以下内容：

attr_encrypted :social_security_no, :key => 'a secret key'

该应用不会在数据库中保存social_security_no或encrypted_social_security_no。

我也尝试了spectator-attr_encrypted gem。但是，现在它发出以下错误：

/home/ashish/.rvm/gems/ruby-2.0.0-p0@lendty/gems/activerecord-3.2.13/lib/active_record/dynamic_matchers.rb:55:in 'method_missing': undefined method 'attr_encrypted' for #<Class:0x0000000824f768> (NoMethodError)

那么，有什么方法可以摆脱这个问题吗？或者，是否有一个分叉版本的gem可以正常使用Rails 3.2.13和Ruby 2.0.0？

而且，这是我的模特：

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

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :first_name, :last_name, :evening_phone, :daytime_phone, :social_security_no
  attr_encrypted :social_security_no, :key => '3243serw54325325435sdrtf34453454325sdt346546'

  # Validations
  validates_uniqueness_of :social_security_no, :email

  # Geocoding 
  geocoded_by :current_sign_in_ip
  after_validation :geocode

  # Associations
  has_many :loans
  has_many :borrowers, :through => :loans

  # Scopes
  scope :verified, where(verified: true)

  def full_name
    first_name.to_s + " " + last_name
  end

end

Answer 1

只是一个猜测，但我认为问题出在validates_unqiueness_of中。我的一位同事通过编写自己的验证来解决这个问题。

validate :must_have_a_valid_email


def must_have_a_valid_email
  if email.present?
    leaders = Leader.where(:encrypted_email => Leader.encrypt_email(self.email))
    leaders = leaders.where('id != ', self.id) if self.persisted?
    self.errors.add(:email, "This email address is in use") if leaders.count > 0
  end
end

RoR：attr_encrypted没有在数据库上保存数据
