ROR - rails - factory_girl不应该不工作(如预期)

Question

问题是我预计第二个it会失败，第三个会通过，但情况正好相反。2分及格，3分不及格。有人知道为什么吗?

规范/模型/user_spec.rb

require 'spec_helper'
describe User do
  it 'has a valid factory' do
    FactoryGirl.create(:user).should be_valid
  end
  it 'is invalid with empty email1' do
    # I've also tried
    # FactoryGirl.build(:user, email: nil, validation_scenario: 'create').should be_valid
    FactoryGirl.build(:user, email: nil).should be_valid
  end
  it 'is invalid with empty email2' do
    FactoryGirl.build(:user, email: nil).should_not be_valid
  end
end

规范/工厂/user.rb

require 'faker'
FactoryGirl.define do
  factory :user do |u|
    u.email                 { Faker::Internet.email }
    u.password              'password'
    u.password_confirmation 'password'
  end
end

模型/user.rb

class User < ActiveRecord::Base
  attr_accessor :password, :validation_scenario
  # validate on user create/update
  with_options if: -> user { ['create', 'update'].include? user.validation_scenario } do |user|
    user.validates_confirmation_of :password
    user.validates_presence_of :password, :on => :before_create
    user.validates_presence_of :email, :password
    user.validates_uniqueness_of :email
    user.validates_format_of :email, :with =>/.+@.+..+/i
  end
  # validate on resend email cofirmation/reset password
  with_options if: -> user { ['send_email_confirmation', 'reset_password'].include? user.validation_scenario } do |user|
    user.validates_presence_of :email
    user.validates_format_of :email, :with =>/.+@.+..+/i
  end
  ...

控制器/user_controller.rb

class UsersController < ApplicationController
  def create
    @user = User.new(user_params)
    @user.validation_scenario = 'create'
    respond_to do |format|
      if @user.save
        format.html { redirect_to root_url, notice: 'User was successfully created.' }
      else
        format.html { render action: 'new' }
      end
    end
  end
  def user_params
    params.require(:user).permit(:email, :password, :password_confirmation)
  end
end

事情是，我没有设置validation_scenario任何地方。现在:

规范/工厂/用户。Rb看起来像这样:

require 'faker'
FactoryGirl.define do
  factory :user do |u|
    u.email                 { Faker::Internet.email }
    u.password              'password'
    u.password_confirmation 'password'
  end
  factory :create_user, parent: :user do |u|
    u.validation_scenario   'create'
  end
end

和规范/模型/user_spec.rb

require 'spec_helper'
describe User do
  it 'has a valid factory' do
    FactoryGirl.create(:create_user).should be_valid
  end
  it 'is invalid with empty email' do
    FactoryGirl.build(:create_user, email: nil).should_not be_valid
  end
  it 'is invalid with empty password' do
    FactoryGirl.build(:create_user, password: nil).should_not be_valid
  end
  it 'is invalid with empty password_confirmation' do
    FactoryGirl.build(:create_user, password: nil).should_not be_valid
  end
end
