ruby-on-rails – Rails教程3第7章：用户模型Rspec测试失败

概述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::Baseattr_accessible :name, :emailemail_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/ivalidates :name, 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::Baseattr_accessible :name,:emailemail_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/ivalIDates :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)    endprivatedef encrypt_password  self.salt = make_salt unless has_password?(password)  self.encrypted_password = encrypt(password)enddef encrypt(string)  secure_hash("#{salt}--#{string}")enddef make_salt  secure_hash("#{Time.Now.utc}--#{password}")enddef secure_hash(string)  Digest::SHA2.hexdigest(string)endend

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" dobefore(:each) do      @user = User.create!(@attr)    end    it "should have a password attribute" do      @user.should respond_to(:password)    endit "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  endend

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
