Question

我正在通过Hartl的Rails教程。我已经达到了第7章，但是我的一个RSpec测试用例失败了，特别是处理不匹配密码的那个：

describe "has_password? method" do

    it "should be true if the passwords match" do
        @user.has_password?(@attr[:password]).should be_true
    end

    it "should be false if the passwords don't match" do
        @user.has_password?("invalid").should be_false
    end
end

终端输出：故障：

  1) User password encryption has_password? method should be false if the passwords don't match
 Failure/Error: @user.has_password?("invalid").should be_false
   expected "273725daa81e74764ea1e941a0789da7d580656cd321c64e39d1389f6a7e14d9" to be false
 # ./spec/models/user_spec.rb:111

这是我的/user.rb代码：

require 'digest'
class User < ActiveRecord::Base
attr_accessor :password
attr_accessible :name, :email, :password, :password_confirmation

email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

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

validates :password, :presence     => true,
                     :confirmation => true,
                     :length       => { :within => 6..40}


before_save :encrypt_password

def has_password? (submitted_password)
    encrypted_password = encrypt(submitted_password)

end

private 

    def encrypt_password
        self.salt = make_salt unless has_password? (password)
        self.encrypted_password = encrypt(password)
    end

    def encrypt(string)
        secure_hash("#{salt}--#{string}")
    end

    def make_salt
        secure_hash("#{Time.now.utc}--#{password}")
    end

    def secure_hash(string)
        Digest::SHA2.hexdigest(string)
    end


end

我似乎无法弄清楚我的生活有什么不妥。我很感激帮助！

Answer 1

使用has_password?方法

encrypted_password = encrypt(submitted_password)需要阅读： encrypted_password == encrypt(submitted_password)
