我一直在成功地遵循Rails教程3,直到我进入第7章并实现了用户模型,现在我的rspec一直在失败.

这是我的user.rb文件输出

class User < ActiveRecord::Base
attr_accessible :name,:email

email_regex = /A[w+-.]+@[a-zd-.]+.[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,:confirmation => true,:length => { :within => 6..40 }

before_save :encrypt_password

# Return tue if the user's password matches the submitted password.
    def has_password?(submitted_password)
        encrypted_password == encrypt(submitted_password)
    end

    def self.authenticate(email,submitted_password)
        user = find_by_email(email)
        return nil  if user.nil?
        return user if user.has_password?(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

这是我的users_spec.rb

require 'spec_helper'

describe User do

  before(:each) do
  @attr = { 
  :name => "Example User",:email => "user@example.com",:password => "foobar",:password_confirmation => "foobar"
    }
  end

  it "should create a new instance given a valid attribute" do
    User.create!(@attr)
  end

  it "should require a name" do
    no_name_user = User.new(@attr.merge(:name => ""))
    no_name_user.should_not be_valid
  end

  it "should require an email address" do
    no_email_user = User.new(@attr.merge(:email => ""))
    no_email_user.should_not be_valid
  end

  it "should reject names that are too long" do
    long_name = "a" * 51
    long_name_user = User.new(@attr.merge(:name => long_name))
    long_name_user.should_not be_valid
  end

  it "should accept valid email addresses" do
    addresses = %w[user@foo.com THE_USER@foo.bar.org first.last@foo.jp]
    addresses.each do |address|
      valid_email_user = User.new(@attr.merge(:email => address))
      valid_email_user.should be_valid
    end
  end

  it "should reject invalid email addresses" do
    addresses = %w[user@foo,com user_at_foo.org example.user@foo.]
    addresses.each do |address|
      invalid_email_user = User.new(@attr.merge(:email => address))
      invalid_email_user.should_not be_valid
    end
   end

  it "should reject duplicate email addresses" do
    User.create!(@attr)
    user_with_duplicate_email = User.new(@attr)
    user_with_duplicate_email.should_not be_valid
  end

  it "should reject email addresses identical up to case" do
    upcased_email = @attr[:email].upcase
    User.create!(@attr.merge(:email => upcased_email))
    user_with_duplicate_email = User.new(@attr)
    user_with_duplicate_email.should_not be_valid
  end

  describe "passwords" do

before(:each) do
      @user = User.create!(@attr)
    end

    it "should have a password attribute" do
      @user.should respond_to(:password)
    end

it "should have a password confirmation attribute" do
  @user.should respond_to(:password_confirmation)
end
  end

      describe "password validations" do

    it "should require a password" do
      User.new(@attr.merge(:password => "",:password_confirmation => "")).
        should_not be_valid
    end

    it "should require a matching password confirmation" do
      User.new(@attr.merge(:password_confirmation => "invalid")).
        should_not be_valid
    end

    it "should reject short passwords" do
      short = "a" * 5
      hash = @attr.merge(:password => short,:password_confirmation => short)
      User.new(hash).should_not be_valid
    end

    it "should reject long passwords" do
      long = "a" * 41
      hash = @attr.merge(:password => long,:password_confirmation => long)
      User.new(hash).should_not be_valid
    end
  end
end

最后这是我的rspec的输出

关于发生了什么的任何想法?我已经坚持了一个星期了

解决方法

您的模型上没有可访问的密码或password_confirmation属性.更改:

attr_accessible :name,:email

至:

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