factorygirl create model association NoMethodError: undefined method

Question

Когда я пытаюсь запустить FactoryGirl.create(:job, :purchased) Я получаю следующую ошибку. Я уже давно сражаюсь с этим, и я считаю, что у меня проблема плюрализации.

Выпуск

Модели

class Job < ActiveRecord::Base 
    belongs_to :company 
    belongs_to :category 
    has_one :coupon 
    has_many :payments 
end 

class Payment < ActiveRecord::Base 
    belongs_to :job 
    belongs_to :coupon 
end 

class Coupon < ActiveRecord::Base 
    belongs_to :job 
end

TRAITS РАБОЧИЕ

trait :purchased do |job| 
    job.reviewed_at { Time.now } 
    job.start_at { Time.now } 
    job.end_at { AppConfig.product['settings']['job_active_for_day_num'].day.from_now }

Answer 1

В вашем trait ваши определяют association :payment, factory: :payment но работа has_many платежей.

Для работы, ваши модели должны быть:

class Job < ActiveRecord::Base 
    belongs_to :payment 
end 

class Payment < ActiveRecord::Base 
    has_many :jobs 
end 

Если вы хотите сохранить вашу модель, как у вас есть и создать черт с работой, содержащей нескольких платежей, что вам нужно сделать что-то вроде этого:
