Question

尝试使用from random import randint def playGame() while pipisuyu == 1: secim = input("Taas kagit....") AI = randint(0, 2) if secim == "Tas" and AI == 0: print ("Rakibiniz de Tas secti, berabere!") elif secim == "Tas" and AI == 1: print ("Rakibiniz kagit secmisti. Kaybettin!") pipisuyu -= 1 elif secim == "Tas" and AI == 2: print ("Rakibiniz makas secmisti. Kazandiniz!") pipisuyu -= 1 elif secim == "Kagit" and AI == 0: print ("Rakibiniz tas secmisti. Kazandiniz!") pipisuyu -= 1 elif secim == "Kagit" and AI == 1: print ("Rakibiniz de kagit secmisti. Berabere!") elif secim == "Kagit" and AI == 2: print ("Rakibiniz makas secmisti. Kaybettiniz!") pipisuyu -= 1 elif secim == "Makas" and AI == 0: print ("Rakibiniz tas secmisti. Kaybettiniz!") pipisuyu -= 1 elif secim == "Makas" and AI == 1: print ("Rakibiniz kagit secmisti. Kazandiniz!") pipisuyu -= 1 elif secim == "Makas" and AI == 2: print ("Rakibiniz de makas secmisti. Berabere!") while True: playGame()创建地方实例，但收到以下错误：

FactoryGirl.create(:place)

无法弄清楚原因，因为在我的工厂里我明确设置了town_city：

放置工厂：

 Failure/Error: FactoryGirl.create(:place)
 ActiveRecord::StatementInvalid:
   PG::NotNullViolation: ERROR:  null value in column "town_city" violates not-null constraint
   DETAIL:  Failing row contains (1, 2017-07-14 13:32:41.246627, 2017-07-14 13:32:41.246627, 51.476900, 0.000010, Greenwich Observatory, Greenwich, London, null, 24849 Lesch Garden, null, null, null, MF4 1FO, null, null, null, null, 1, null, f).

 # ./spec/requests/api/v1/events_spec.rb:5:in `block (2 levels) in <top (required)>'

Page＆amp;可分页特征：

factory :place, traits: [:pageable] do
  town_city 'my hardcoded value'
  latitude { rand(50.0...53.0) }
  longitude { rand(-2.0...2.0) }
  street_address { Faker::Address.street_address }
  postcode { Faker::AddressUK.postcode }
  association :region, factory: :region
end

区：

trait :pageable do
  association :page, strategy: :build
end

factory :page do
  sequence(:title) { |n| "#{Faker::Product.product_name}-#{n}" }
  association :user
  association :cover_image, factory: :image
  telephone { Faker::PhoneNumber.phone_number }
  description { generate :paragraphs_seq }
end

任何想法可能是什么原因？

事实证明，我的Place模型中有 before_validation 挂钩，试图使用Region字段数据重置 town_city 。所以我想我必须修改我的地区工厂

FactoryGirl：非空约束违规
