Rspec factory_girl ActiveMerchant undefined method `credit_card=' - ruby-on-rails-3

Question

I'm attempting to test the creation of an Reservation model that involves processing a payment with ActiveMerchant upon creation.
The initial setup for payment processing involved following the ActiveMerchant Railscasts. Payments are working fine within the app. (http://railscasts.com/episodes/145-integrating-active-merchant)
I've tried creating the credit_card object within the Reservation factory and within it's own ":valid_credit_card" factory...
The basic test is just attempting to verify the Reservation can be created.
Test results:
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
The Reservation belongs_to a user and has_many rooms through 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
And the spec/models/reservation_spec.rb. Using #credit_card Factory.build causes errors about "saving" the credit_card.
If I remove the line f.credit_card :valid_credit_card I get the NoMethodError for :month
even though :month is listed in attr_accessor. The creation of a reservation within the app does work.
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
What am I overlooking / doing incorrectly...?
Reservation model excerpts
class Reservation < ActiveRecord::Base
# relationships
belongs_to :user
has_many :reservation_sets,
:dependent => :destroy
has_many :rooms,
:through => :reservation_sets
has_many :transactions,
:class_name => 'ReservationTransaction',
:dependent => :destroy
attr_accessor :card_number, :card_verification, :card_expires_on, :card_type, :ip_address, :rtype, :month, :year
# other standard validations
validate :validate_card, :on => :create
# other reservation methods...
# gets paid upon reservation creation
def pay_deposit
# Generate active merchant object
ReservationTransaction.gateway =
ActiveMerchant::Billing::AuthorizeNetGateway.new({
:login => rooms[0].user.gateway_login,
:password => rooms[0].user.gateway_password
})
response = ReservationTransaction.gateway.purchase(deposit_price_in_cents, credit_card, purchase_options)
t = transactions.create!(:action => "purchase", :amount => deposit_price_in_cents, :response => response)
if response.success?
update_attribute(:reserved_at, Time.now)
# update state
payment_captured!
else
transaction_declined!
errors.add :base, response.message
end
t.card_number = credit_card.display_number
t.save!
response.success?
end
def validate_card
unless credit_card.valid?
credit_card.errors.full_messages.each do |message|
errors.add :base, message #_to_base message
end
end
end
def credit_card
#credit_card ||= 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
)
end
And the create action from the Reservation Controller
def create
#reservation = Reservation.new(params[:reservation])
#reservation.arrival = session[:arrival]
#reservation.nights = session[:nights]
#reservation.number_kids = session[:number_kids]
#reservation.number_adults = session[:number_adults]
session[:creating_reservation] = 1
#reservation.user_id = #reservation.rooms[0].user_id
session[:owner] = #reservation.user_id
#rooms = Room.all
#reservation.ip_address = request.remote_ip
# get room owner...
#owner = User.find(#reservation.user_id)
respond_to do |format|
if #reservation.save
if #reservation.pay_deposit
#set cc...
#reservation.transactions[0].card_number = #reservation.send(:credit_card).display_number
ReservationMailer.reservation_created(#reservation).deliver
ReservationMailer.reservation_notice(#reservation).deliver
session[:arrival] = nil
session[:reservation_id] = #reservation.id
if #owner
thanks_path = "#{#owner.permalink}/reservations/#{#reservation.id}"
else
thanks_path = #reservation
end
format.html { redirect_to #reservation, :notice => 'Reservation was successfully created.' }
format.json { render :json => #reservation, :status => :created, :location => #reservation }
# also trigger email sending or wherever that is
# receipt email and order notification
#
else
# set flash or show message problem w/ transaction
format.html { render :action => "new" }
end
else
format.html { render :action => "new" }
format.json { render :json => #reservation.errors, :status => :unprocessable_entity }
end
end
end

Answer 1

It looks like you are trying to assign credit_card a value, but you don't really have a class accessor. So where you are trying to call f.credit_card :valid_credit_card isn't going to work.
I would remove the f.credit_card :valid_credit_card from your factory and look into using rspec stubs, then you could do something like the following in your rspec test:
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)
This would make it so when your model called credit_card it would return a mocked object.
