NAME

Catalyst::Model::CPI - Business::CPI models for Catalyst

VERSION

version 0.03

SYNOPSIS

In the config:

<model Payments>
    <gateway PayPal>
        api_username   ...
        api_password   ...
        signature      ...
        receiver_email seller@test.com
        sandbox 1
    </gateway>

    <gateway X> ... </gateway>

    <gateway Y> ... </gateway>
</model>

In the controller:

# It should be configured in PayPal's IPN, for example, the notify_url as:
# http://myserver/api/store/notification/PayPal
# Other gateways are similar.
sub gtw_notification : Chained('/api/store') PathPart('notification') Args(1) {
    my ($self, $ctx, $gateway_name) = @_;

    my $model = $ctx->model('Payments');

    if ( !$model->exists($gateway_name) ) {
        my $gtw_list = join ", ", $model->available_gateways;
        die "$gateway_name is not available.\n"
          . "Available gateways are: $gtw_list.";
    }

    my $notification = $model->get($gateway_name)->notify;

    my $purchase = $ctx->model('DB::Purchase')->find( $notification->{payment_id} );
    $purchase->update({ payment_status => $notification->{status} });

    ...
}

sub checkout : Chained('/website/cart') PathPart Args(0) {
    my ($self, $ctx) = @_;

    my $model = $ctx->model('Payments');
    my $cart  = $ctx->session->{cart};

    # create a form for each available gateway
    my @forms = map {
        $model->get($_)->new_cart($cart)->get_form_to_pay("${_}_form")
    } $model->available_gateways;

    $ctx->stash->{checkout_forms} = \@forms;
}

DESCRIPTION

This module connects CPI gateways to a Catalyst application. It automatically loads the configuration from Catalyst and uses it to instantiate the gateways when requested through this model.

METHODS

available_gateways

List all the class names for the installed CPI gateways.

my @gateways = $ctx->model('Payments')->available_gateways;

get

Returns a new instance of the gateway, with all the configuration passed as arguments to the constructor.

my $cart = $ctx->model('Payments')->get('PayPal')->new_cart(...);

exists

Check whether the provided gateway is really installed.

if ($model->exists($gateway)) {
    ...
}

ACCEPT_CONTEXT

Saves the request, so that $gateway->notify can receive it automatically. See the Catalyst docs for details.

CONFIGURATION

<model Payments>
    <gateway PayPal>
        api_username   ...
        api_password   ...
        signature      ...
        receiver_email seller@test.com
        sandbox 1
    </gateway>

    <gateway PagSeguro>
        receiver_email seller@test.com
        ...
    </gateway>

    <gateway Custom>
        foo bar
    </gateway>
