我正在尝试测试一个预订模型的创建，该模型涉及在创建时使用ActiveMerchant处理付款。
ActiveMerchant Railscast之后涉及的支付处理的初始设置。付款在应用程序中正常运行。 （http://railscasts.com/episodes/145-integrating-active-merchant）
我已尝试在credit_card工厂内及其自己的“{valid_credit_card”工厂内创建Reservation对象...
基本测试只是试图验证可以创建预约。 测试结果：
1) Reservation should have a valid factory
Failure/Error: @current_reservation = Factory.create(:reservation)
NoMethodError:
undefined method `credit_card=' for #<Reservation:0xb5f6173c>
# ./spec/models/reservation_spec.rb:11
预订属于用户，并且has_many rooms通过reservation_sets
Factory.define :reservation do |f|
f.association :user
f.rooms { |a| [a.association(:room)] }
f.arrival Time.now + 2.weeks
f.nights 2
f.phone "555-123-1234"
f.credit_card :valid_credit_card
end
Factory.define :valid_credit_card, :class => ActiveMerchant::Billing::CreditCard do |f|
expiration_date = Time.zone.now + 1.year
f.type "visa"
f.number "4111111111111111"
f.verification_value "333"
f.month expiration_date.strftime("%m")
f.year expiration_date.strftime("%y")
f.first_name "Bob"
f.last_name "Smith"
end
spec / models / reservation_spec.rb。使用@credit_card Factory.build会导致有关“保存”credit_card的错误。
如果我删除了行f.credit_card：valid_credit_card，我得到:month的NoMethodError
即使:month中列出了attr_accessor。在应用程序中创建预订确实有效。
1) Reservation should have a valid factory
Failure/Error: @current_reservation = Factory.create(:reservation)
NoMethodError:
undefined method `month' for nil:NilClass
describe Reservation do
before :each do
@smith = Factory.create(:user)
@room = Factory.create(:room)
#@credit_card = Factory.build(:valid_credit_card)
end
it "should have a valid factory" do
@current_reservation = Factory.create(:reservation)
@current_reservation.should be_valid
end
end
我忽略了什么/做错了什么......？

答案 0 :(得分：0)
您似乎正在尝试为credit_card分配一个值，但实际上并没有class accessor。因此，您尝试呼叫f.credit_card :valid_credit_card的地方无效。
我会从您的工厂中移除f.credit_card :valid_credit_card并查看使用rspec stubs，然后您可以在rspec测试中执行以下操作：
mock_cc = ActiveMerchant::Billing::CreditCard.new(
:type => card_type,
:number => card_number,
:verification_value => card_verification,
:month => card_expires_on.month,
:year => card_expires_on.year,
:first_name => first_name,
:last_name => last_name
)
Reservation.stub(:credit_card).and_return(mock_cc)
当你的模型调用credit_card时，它会返回一个模拟对象。
