我有一个相当矮胖的工厂女孩特质,接受参数并创建一个has_many关系.我可以称这种特性作为另一种特性的一部分来干燥特性,或者在将它们传递给工厂时更容易将特征捆绑在一起.我不知道怎么做的是当我从另一个特征中调用它或者做什么时,如何将params传递给一个特征.
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
解决方法
：with_price特征需要与您正在设置的其他属性位于不同的行上,即代替：
trait :with_usd_price do with_price short_name: 'USD' end
用这个：
trait :with_usd_price do with_price short_name: 'USD' end
