= Simplified Sermepa

Plugin for doing Sermepa (La Caixa, BBVA, MasterCard) payments.

== Usage

In order to use Simplified Sermepa you need:

- A <tt>config/sermepa.yml</tt> file explained above.
- A model used to store orders by default Order but configurable at `sermepa.yml`.
- A model used to store transaction details by default OrderTransaction 
but configurable at `sermepa.yml`.

The Order model attributes:

    Order
      token
      ...

The OrderTransaction model attributes:

    OrderTransaction
      raw_response
      order_id
      created_at
      updated_at

== ToDo

- Tests.
- Generators.
- Models shouldn't be hardcoded.
- Method to generate token.

== Configuration

After installing the plugin a configuration file named `sermepa.yml` will 
be created under `RAILS_ROOT/config`

Example:

    development:
      fuc: 201920191
      secret_key: h2u282kMks01923kmqpo
      payment_url: https://sis-t.sermepa.es:25443/sis/realizarPago
      ipn_url: http://sample.no-ip.org:3000/sermepa_backend/create
      success_url: http://0.0.0.0:3000/store/thanks
      failure_url: http://0.0.0.0:3000/store/checkout?message=error
    test:
      ...
    production:
      ...

=== Testing

You can use the following credit card to test your application.

    Fuc: 201920191
    Secret Key: h2u282kMks01923kmqpo
    Tarjeta: 4548812049400004
    Fecha de caducidad: 12/07
    CIP: 123456

== Example

On your models ...

    ##
    # app/models/order.rb
    #
    class Order < ActiveRecord::Base
      use_sermepa
    end

After adding <tt>use_sermepa</tt> to your model, it will be enable to 
accept transactions.

    >> Order.find_by_token('QWERTY').ipn_success?
    => true
    >> Order.find_by_token('QWERTY).ipn_code
    => '0000'

So after creating an order you can deliver the confirmation email to your 
client or run the desired task.

    class Order < ActiveRecord::Base

      use_sermepa

      after_create :notify_dispatch_and_user

      def notify_dispatch_and_user
        if self.ipn_success?
          # Deliver email with ActiveMailer ...
        end
      end

    end

On your views ...

    ##
    # app/views/payments/confirm.html.erb
    #
    <%= form_submit_to_sermepa(amount, token) %>
