# app/controllers/payments_controller.rb
class PaymentsController < ApplicationController
def new
@payment = Payment.new
@creditcard = ActiveMerchant::Billing::CreditCard.new
end
def create
@payment = Payment.new(params[:payment])
@creditcard = ActiveMerchant::Billing::CreditCard.new(params[:creditcard])
@payment.valid_card = @creditcard.valid?
if @payment.valid?
@payment = @payment.process_payment(@creditcard)
if @payment.success?
@payment.save
flash[:notice] = I18n.t('payment.success')
redirect_to payments_url and return
else
flash[:error] = I18n.t('payment.failed')
end
end
render :action => :new
end
end
Generate & Migrate Payment Model
rails g model payment status:string amount:float transaction_number:string
rake db:migrate
Payment Model
# app/models/payment.rb
class Payment < ActiveRecord::Base
PROCESSING, FAILED, SUCCESS = 1, 2, 3
validates :valid_card, :inclusion => {:in => [true], :message => 'Invalid Credit Card'}
validates :amount, :presence => true, :numericality => { :greater_than => 0 }
def process_payment(creditcard)
ActiveMerchant::Billing::Base.mode = auth['mode'].to_sym
self.status = PROCESSING
response = gateway.purchase(amount * 100, creditcard)
if response.success?
self.transaction_number = response.subscription_id
self.status = SUCCESS
else
self.status = FAILED
end
return self
rescue Exception => e
self.status = FAILED
return self
end
def success?
self.status == SUCCESS
end
private
def gateway
ActiveMerchant::Billing::AuthorizeNetGateway.new(
:login => auth['login'],
:password => auth['key'])
end
def auth
@@auth ||= YAML.load_file("#{Rails.root}/config/authorize_net.yml")[Rails.env]
end
