ruby-on-rails - Michael Hartl 的教程第 6 章 : Failing Test due to Syntax_error on model

Question

list 6.27 中的测试旨在 pass ，但是我不断收到 13 个错误，这些错误都对我引用了相同的语法错误:

Syntax Error:       SyntaxError: /home/action/workspace/app/app/models/user.rb:6: syntax error, unexpected ':', expecting keyword_end

这似乎是导致错误的模型，但我没有发现它有任何问题:

  1  class User < ActiveRecord::Base
  2  validates :name,  presence: true, length: { maximum: 50 }
  3  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  4  validates :email, presence: true, length: { maximum: 255 },
  5                         format: { with: VALID_EMAIL_REGEX }
  6                         uniqueness:  {case_sensitive: false} 
  7  end 

最初它说错误是第 6 行，意外的关键字“:”在唯一性和左括号之间，但经过一些修改之后，这似乎已经停止了。

关于本章的一些关于 SO 的问题似乎源于测试本身的缩进，因此为了完整起见，我将它们包括在这里:

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  def setup
    @user = User.new(name: "Example User", email: "user@example.com")
  end

  test "should be valid" do
    assert @user.valid?
  end

  test "name should be present" do
    @user.name = "     "
    assert_not @user.valid?
  end

  test "name should not be too long" do
    @user.name = "a" * 51
    assert_not @user.valid?
  end

  test "email should not be too long" do
    @user.email = "a" * 244 + "@example.com"
    assert_not @user.valid?
  end  

  test "email validation should accept valid addresses" do
    valid_addresses = %w[user@example.com USER@foo.COM A_US-ER@foo.bar.org first.last@foo.jp alice+bob@baz.cn]
    valid_addresses.each do |valid_address|
      @user.email = valid_address
      assert @user.valid?, "#{valid_address.inspect} should be valid"
     end
  end

  test "email validation should reject invalid addresses" do
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example. foo@bar_baz.com foo@bar+baz.com]
    invalid_addresses.each do |invalid_address|
      @user.email = invalid_address
      assert_not @user.valid?, "#{invalid_address.inspect} should be invalid"
    end
  end

  test "email addresses should be unique" do
    duplicate_user = @user.dup
    duplicate_user.email = @user.email.upcase
      @user.save
      assert_not duplicate_user.valid?
    end
  end

Answer 1

第 5 行末尾缺少 ,。

请参阅 Listing 6.24 处的代码

class User < ActiveRecord::Base
  validates :name,  presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
                    format: { with: VALID_EMAIL_REGEX },
                    uniqueness: true
end
