Question

我在Hartl的RoR指南第10章中不断得到这两个错误，似乎无法找到解决方案。我已经故障排除了一段时间，但答案继续避开我。 USER.rb有什么问题吗？

 FAIL["test_name_should_not_be_too_long", UserTest, 0.436818]
 test_name_should_not_be_too_long#UserTest (0.44s)
        Expected true to be nil or false
        test/models/user_test.rb:25:in `block in <class:UserTest>'

 FAIL["test_name_should_be_present", UserTest, 0.441668]
 test_name_should_be_present#UserTest (0.44s)
        Expected true to be nil or false
        test/models/user_test.rb:15:in `block in <class:UserTest>'

这是我的User_test

require 'test_helper'

class UserTest < ActiveSupport::TestCase

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

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

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

test "email should be present" do
    @user.email = "     "
    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

  test "email addresses should be saved as lower-case" do
    mixed_case_email = "Foo@ExAMPle.CoM"
    @user.email = mixed_case_email
    @user.save
    assert_equal mixed_case_email.downcase, @user.reload.email
  end


  test "password should have a minimum length" do
    @user.password = @user.password_confirmation = "a" * 5
    assert_not @user.valid?
  end

  test "authenticated? should return false for a user with nil digest" do
    assert_not @user.authenticated?(:remember, '')
  end

end

Answer 1

这是一个很好的教程。我看到你在user.rb中缺少验证

  validates :name,  presence: true, length: { maximum: 50 }

将此行添加到user.rb模型规范中，并且应解决这两个错误。
