FactoryGirl Проблемы с временем и DateTime

Question

Кажется, у меня возникли проблемы с созданием объекта Time с помощью FactoryGirl. Когда я это делаю:

factory :invite do |n| 
    fromtime Time.now + 1.weeks 
    totime Time.now + 1.weeks + 1.hour 
end 

Завод прекрасно работает, но я хочу иметь много приглашений, которые находятся в последовательности. Так что, когда я делаю это:

factory :invite do |n| 
    fromtime Time.now + n.weeks 
    totime Time.now + n.weeks + 1.hour 
end 

Я получаю эту ошибку

Как я могу получить несколько приглашений с последовательными объектами времени?

Answer 1

Try:

factory :invite do 
sequence(:fromtime) { |n| Time.now + n.weeks } 
sequence(:totime) { |n| Time.now + n.weeks + 1.hour } 
end 

Надеется, что это помогает!
