我正在关注Michael Hartl的RoR教程,它涵盖了密码加密的基础知识.这是目前的用户模型:

class User < ActiveRecord::Base
    attr_accessor :password

    attr_accessible :name, :email,: password, :password_confirmation

    email_regex = /^[A-Za-z0-9._+-]+@[A-Za-z0-9._-]+\.[A-Za-z0-9._-]+[A-Za-z]$/
                                              #tests for valid email addresses.

    validates :name, :presence => true,
                     :length => {:maximum => 50}
    validates :email, :presence => true,
                      :format => {:with => email_regex},
                      :uniqueness => {:case_sensitive => false}
    validates :password, :presence => true,
                         :length => {:maximum => 20, :minimum => 6},
                         :confirmation => true

    before_save :encrypt_password

    private

    def encrypt_password
        self.encrypted_password = encrypt(password)
    end

    def encrypt(string)
        string
    end
end

我发布了一个关于before_save不工作的上一个问题,事实证明我不小心做的是将我的encrypt_password写成:
