Rails 具有可选模型关联的 FactoryGirl 工厂
Rails FactoryGirl Factory with optional model association
根据,我不得不更新我的工厂。我正在尝试创建一个可以创建优惠券的条件,但只有在执行时才分配作业 ID,即:
FactoryGirl.define do
factory :coupon do
code { rand(25**25) }
percent_discount { rand(100**1) }
start_at { Time.now }
end_at { 30.day.from_now }
trait :executed do |c|
job
c.executed_at { Time.now }
end
end
end
您似乎应该从优惠券模型中删除 validates :job, presence: true
或 validates :job_id, presence: true
之类的内容
您可以在工厂中使用回调。这是一个例子:
FactoryGirl.define do
factory :coupon do
code { rand(25**25) }
percent_discount { rand(100**1) }
start_at { Time.now }
end_at { 30.day.from_now }
after(:create) do |c|
#do job related stuff
end
end
end

更新
根据您最后的评论,我认为 trait 不会有用。这是我的理解 create coupon > do some process > execute coupon > assign job
。所以在创建优惠券之后,我认为优惠券有一些延迟/处理逻辑。所以这时候执行coupon的时候需要创建job的object,并关联到那个coupon上。我相信以下内容适合该流程:
FactoryGirl.define do
factory :coupon do
code { rand(25**25) }
percent_discount { rand(100**1) }
start_at { Time.now }
end_at { 30.day.from_now }
#This trait is used in case,
#if you want job to be assigned to coupon
#for example create(:coupon,:executed)
trait :executed do |c|
association :job, factory: [:job]
c.executed_at { Time.now }
end
end
end
#In Test Case
@coupon = create(:coupon)
#have some test for coupon before execution
#now executing coupon
@coupon.update_attributes(job_id: create(:job), executed_at: Time.now)
根据
FactoryGirl.define do
factory :coupon do
code { rand(25**25) }
percent_discount { rand(100**1) }
start_at { Time.now }
end_at { 30.day.from_now }
trait :executed do |c|
job
c.executed_at { Time.now }
