ruby-on-rails - FactoryGirl 电子邮件已被占用

Question

我正在尝试用 FactoryGirl 实例化多个对象(拥有唯一电子邮件的客人)

  guests = create_list(:guest, 3)

但是我得到错误:

 Failure/Error: guests = create_list(:guest, 3)

 ActiveRecord::RecordInvalid:
   Validation failed: Email has already been taken

这里是我的工厂:

FactoryGirl.define do
  factory :guest do
    email Faker::Internet.unique.email
    firstname 'John'
    lastname  'Doe'
    password 'test'
    password_confirmation 'test'

    factory :guest_with_bookings do
      email "#{SecureRandom.hex}@test.com"
      transient do
        bookings_count 2
      end
      after(:create) do |guest, evaluator|
        create_list(:booking, evaluator.bookings_count, guests: [guest])
      end
    end
  end
end

即使使用 Faker::Internet.unique.email，当我尝试创建超过 1 个访客时它也不起作用

Answer 1

在你的工厂中使用顺序

FactoryGirl.define do
  factory :guest do
    sequence(:email) { |n| "name_#{n}@example.com" }

或者结合Faker

FactoryGirl.define do
  factory :guest do
    sequence(:email) { |n| Faker::Internet.unique.email("Nancy_#{n}") }
