我有以下来自 Michael Hartl 的 rails 教程的规范，并且 在6.2.3 长度验证之前它都可以正常工作 

require 'spec_helper'

describe User do

  before { @user = User.new(name: "Example User", email: "user@example.com")}

  subject { @user}

  it { should respond_to(:name) }
  it { should respond_to(:email) }

  it { should be_valid }

  describe "when name is not present" do
    before { @user.name = " " }
    it { should_not be_valid }
  end

  describe "when email is not present" do
    before { @user.email = " "  }
    it { should_not be_valid  }
  end

  describe "when name is too long" do
    before { @user.name = "a" * 51 }
    it { should_not be_valid }
  end
end

在6.2.4 格式验证之后，当我添加下面的代码时，它不起作用

describe "when email format is invalid" do
    it "should be invalid" do
      addresses = %w[user@foo,com user_at_foo.org example.user@foo.]
      addresses.each do |invalid_address|
        @user.email = invalid_address
        @user.should_not be_valid
      end
    end
  end


  describe "when email format is valid" do
    it "should be valid" do
      addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn]
      addresses.each do |valid_address|
        @user.email = valid_address
        @user.should be_valid
      end
    end
  end

这是完整的文件

require 'spec_helper'

describe User do

  before { @user = User.new(name: "Example User", email: "user@example.com")}

  subject { @user}

  it { should respond_to(:name) }
  it { should respond_to(:email) }

  it { should be_valid }

  describe "when name is not present" do
    before { @user.name = " " }
    it { should_not be_valid }
  end

  describe "when email is not present" do
    before { @user.email = " "  }
    it { should_not be_valid  }
  end

  describe "when name is too long" do
    before { @user.name = "a" * 51 }
    it { should_not be_valid }
  end

  describe "when email format is invalid" do
    it "should be invalid" do
      addresses = %w[user@foo,com user_at_foo.org example.user@foo.]
      addresses.each do |invalid_address|
        @user.email = invalid_address
        @user.should_not be_valid
      end
    end
  end


  describe "when email format is valid" do
    it "should be valid" do
      addresses = %w[user@foo.COM A_US-ER@f.b.org frst.lst@foo.jp a+b@baz.cn]
      addresses.each do |valid_address|
        @user.email = valid_address
        @user.should be_valid
      end
    end
  end
end

这是错误日志，知道如何解决吗？

我修好了，我从这个链接得到了帮助 -点击这里

我认为这是我VALID_EMAIL_REGEX的错

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

实际是：

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

下次我将代码放在github上并在这里放一个链接，那就是
