Ruby on rails 带有事务性_fixture的Rspec=true抛出唯一性错误

我正在测试我的API，使用Grape和Rails构建，使用RSpec构建，并得到许多唯一性验证错误

我使用config.use\u transactional\u fixtures=true在每次测试后回滚数据库，但我发现以下错误：

  7) API GET /api/v1/quotations returns 200 when there is at least one quotation
     Failure/Error: FactoryGirl.create(:quotation)
     ActiveRecord::RecordInvalid:
       Validation failed: Number has already been taken
     # ./spec/requests/api/quotations_spec.rb:56:in `block (3 levels) in <top (required)>'

更新1 我切换到DatabaseCleaner并尝试调试：

config.after(:each) do

    puts
    puts '####'
    puts Client.all
    puts '####'
    puts Contact.all
    puts '####'
    puts

    DatabaseCleaner.clean

    puts
    puts '####'
    puts Client.all
    puts '####'
    puts Contact.all
    puts '####'
    puts

    # Reset tentant back to `public`
    Apartment::Database.reset

  end

---

实际上，数据库已被清理，因此Contact.all和Client.all在database.clean之后为空。这很让人困惑，因为否则验证错误就不会发生了。

我找到了答案。多亏了这个答案：

我必须用如下序列替换唯一字段：

FactoryGirl.define do

  factory :user do
    name Faker::Name.name
    surname Faker::Name.last_name
    sequence :email do |n|
      "foo#{n}@bar.de"
    end
    password 'secret'
    password_confirmation 'secret'
  end

end

FactoryGirl.define do

  factory :quotation do
    number Faker::Number.number(8)
    title Faker::Lorem.word
    payable Faker::Lorem.sentence
    request
    contact
  end

end

FactoryGirl.define do

  factory :request do
    number Faker::Number.number(8)
    title Faker::Lorem.word
    content Faker::Lorem.sentence
    contact
  end

end
