使用 factory_girl 中的参数从另一个特征调用特征

Question

我有一个相当矮胖的 Factory Girl 特征，它接受参数并创建 has_many 关系。我可以将该特征称为另一个特征的一部分，以干涸特征或在将特征传递给工厂时更容易将它们捆绑在一起。我不知道该怎么做的是当我从另一个特征调用它时如何将参数传递给一个特征，或者该怎么做。

例如

FactoryGirl.define do
  factory :currency do
    name Forgery::Currency.description
    sequence(:short_name) { |sn| "#{Forgery::Currency.code}#{sn}" }
    symbol '$'
  end

  factory :price do
    full_price { 6000 }
    discount_price { 3000 }
    currency
    subscription
  end

  sequence(:base_name) { |sn| "subscription_#{sn}" }

  factory :product do
    name { generate(:base_name) }
    type { "reading" }
    duration { 14 }


    trait :reading do
      type { "reading subscription" }
    end

    trait :maths do
      type { "maths subscription" }
    end

    trait :six_month do
      name { "six_month_" + generate(:base_name) }
      duration { 183 }
    end

    trait :twelve_month do
      name { "twelve_month_" + generate(:base_name) }
      duration { 365 }
    end

    factory :six_month_reading, traits: [:six_month, :reading]
    factory :twelve_month_reading, traits: [:twelve_month, :reading]

    trait :with_price do
      transient do
        full_price 6000
        discount_price 3000
        short_name 'AUD'
      end

      after(:create) do |product, evaluator|
        currency = Currency.find_by(short_name: evaluator.short_name) ||
                     create(:currency, short_name: evaluator.short_name)
        create_list(
          :price,
          1,
          product: product,
          currency: currency,
          full_price: evaluator.full_price,
          discount_price: evaluator.discount_price
        )
      end
    end

    trait :with_aud_price do
      with_price
    end

    trait :with_usd_price do
      with_price short_name: 'USD'
    end
  end
end

create(:product, :with_aud_price) # works
create(:product, :with_usd_price) # fails "NoMethodError: undefined method `with_price=' for #<Subscription:0x007f9b4f3abf50>"

# What I really want to do
factory :postage, parent: :product do
  with_aud_price full_price: 795
  with_usd_price full_price 700
end

Answer 1

:with_price 特征需要与您正在设置的其他属性分开一行，即使用此：

trait :with_usd_price do
  with_price
  short_name: 'USD'
end

而不是这个：

trait :with_usd_price do
  with_price short_name: 'USD'
end

Answer 2

我使用的是 factory_bot 4.8.2，以下是对我有用的：

trait :with_usd_price do
  with_price
  short_name 'USD'
end

使用 factory_girl 中的参数从另一个特征调用特征

Call trait from another trait with params in factory_girl
