ruby-on-rails - Michael Hartl 教程第 6 章 - 语法错误

Question

我正在编写 Michael Hartl 的教程。我在第 6 章。我要进行用户验证。下面的代码是我被告知要使用的代码，但它不起作用。我收到错误消息 syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError)。我没有看到语法错误。有什么建议吗？

require 'spec_helper'

describe User do
  before do
    @user = User.new(name: "Example User", email: "user@example.com")
  end
  subject { @user }
  it { should respond_to(:name) }
  it { should respond_to(:email) }
  it { should respond_to(:password_digest) }
  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.
                     foo@bar_baz.com foo@bar+baz.com]
      addresses.each do |invalid_address|
        @user.email = invalid_address
        @user.should_not be_valid
      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

  describe "when email address is already taken" do
    before do
      user_with_same_email = @user.dup
      user_with_same_email.email = @user.email.upcase
      user_with_same_email.save
    end
    it { should_not be_valid }
  end 
end

我建议您缩进您的代码，这样它会更加明显 end 关键字应该放在哪里(您会立即发现您遗漏了一个)。 (Hartl 在整本书中都这样做。)

例如:

require 'spec_helper'
describe User do
  before do
    @user = User.new(name: "Example User", email: "user@example.com")
  end
  subject { @user }
  it { should respond_to(:name) }
  it { should respond_to(:email) }
  it { should respond_to(:password_digest) }
  it { should be_valid }
  describe "when name is not present" do
    before { @user.name = " " }
    it { should_not be_valid }
  end
end

如果缩进在任何地方都不匹配，它应该跳到你面前，然后你就会知道有问题。
