我已经搜遍了整个地方,似乎没有其他人有这个'加密'方法的问题导致他们的测试失败,虽然看起来很多其他人在第7章遇到了一些困难。没有进一步的说法,
这是Hartl Chapter 7
的链接用户模型文件中的代码和相应的spec文件看起来与他编写的内容完全一致,但仍然无法通过测试。错误?

所以我为每次测试都收到了相同的错误消息,我很想找到原因!
这是我的user.rb:
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 }
#automatically create the virtual attribute for 'password_confirmation'
validates :password, :presence => true,
:confirmation => true,
:length => { :within => 6..40 }
before_save :encrypt_password
#returns true if the users password matches the submitted one
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
和我的user_spec.rb文件:
require 'spec_helper'
require 'digest'

before(:each) do
@attr = {
:name => "User Name",
:email => "example@email.com",

end
end
end
非常感谢任何帮助。我倾注了其他问题,我的代码,并改变了各个方面,试图让测试工作,一切都无济于事。我希望这不是真正愚蠢的东西,我还没有看到。
答案 0 :(得分:3)
您的错误在这里:
def encrypt_string
secure_hash("#{salt}--#{string}")
end
您在以下 encrypt_password 方法中呼叫encrypt
但上述方法名为encrypt_string
:
def encrypt_password
self.salt = make_salt unless has_password?(password)
self.encrypted_password = encrypt(password)
end
只需在方法定义中将encrypt_string
更改为encrypt
,就可以了。
