PayPal Express Gateway

[soichi]

Rails 3.1.3

I would like to use PayPal Express Gateway, and I got information from Rails Casts,

http://railscasts.com/episodes/146-paypal-express-checkout

First of all, in development.rb, I put, 

  config.after_initialize do

    ActiveMerchant::Billing::Base.mode = :test

    paypal_options = { 

    :login => "xxxx_biz_api1.gmail.com",

    :password => "xxxx"

    :signature => "xxxx"

    }

    ::STANDARD_GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(paypal_options)

    ::EXPRESS_GATEWAY = ActiveMerchant::Billing::PaypalExpressGateway.new(paypal_options)

  end

in payments_controller.rb,

  def checkout

    setup_response = EXPRESS_GATEWAY.setup_purchase(5000,

    :ip                => request.remote_ip,

    :return_url        => url_for(:action => 'confirm', :only_path => false),

    :cancel_return_url => url_for(:action => 'index', :only_path => false)

    )

    redirect_to gateway.redirect_url_for(setup_response.token)

  end

well, this gives now an error, 

uninitialized constant PaymentsController::EXPRESS_GATEWAY

Is there anything wrong?

For starters, I'd put the configuration in a standard initializer
rather than an after_initialize block:

config/initializers/activemerchant.rb:

ActiveMerchant::Billing::Base.mode = :test
paypal_options = {
:login => "xxxx_biz_api1.gmail.com",
:password => "xxxx"
:signature => "xxxx"
}
STANDARD_GATEWAY = ActiveMerchant::Billing::PaypalGateway.new(paypal_options)
EXPRESS_GATEWAY =
ActiveMerchant::Billing::PaypalExpressGateway.new(paypal_options)

If you do that does it work?
