=head1 NAME

Package WebGUI::Shop::Transaction

=head1 DESCRIPTION

This package keeps records of every puchase made.

=head1 SYNOPSIS

 use WebGUI::Shop::Transaction;

 my $transaction = WebGUI::Shop::Transaction->new($session, $id);
 
 # typical transaction goes like this:
 my $transaction = WebGUI::Shop::Transaction->create({ cart=>$cart });
 my ($transactionNumber, $status, $message) = $paymentMethod->tryTransaction;
 if ($status eq "somekindofsuccess") {
    $transaction->completePurchase($cart, $transactionNumber, $status, $message);
 }
 else {
    $transaction->denyPurchase($transactionNumber, $status, $message);
 }


=head1 METHODS

These subroutines are available from this package:

=cut

readonly session => my %session;
private properties => my %properties;

#-------------------------------------------------------------------

=cut

sub addItem {
    my ($self, $cartItem) = @_;
    my $item = WebGUI::Shop::TransactionItem->create( $self, $cartItem);

    return undef;
}

=head2 update ( properties )

Sets properties in the transaction.

=head3 properties

A hash reference that contains one of the following:

=head4 cart

A reference to a cart object. Will pull shipping method, shipping address, tax, items, and total from

amount shippingAddressId shippingAddressName shippingAddress1 shippingAddress2 shippingAddress3 shippingCity
shippingState shippingCountry shippingCode shippingPhoneNumber shippingDriverId shippingDriverLabel shippingPrice
taxes shopCreditDeduction

You can also use the addItem() method to manually add items to the transaction rather than passing a cart full of items.

any of the properties that are set by payment address automatically: paymentAddressId paymentAddressName
paymentAddress1 paymentAddress2 paymentAddress3 paymentCity paymentState paymentCountry paymentCode
paymentPhoneNumber 

=head4 paymentMethod

A reference to a WebGUI::Shop::PayDriver subclass that is used to make payment. Alternatively you can set
manually any of the properties that are set by payment method automatically: paymentDriverId paymentDriverLabel

=head4 isSuccessful

A boolean indicating whether the transaction was completed successfully.

=head4 transactionCode

The transaction id or code given by the payment gateway.

=head4 statusCode

The status code that came back from the payment gateway when trying to process the payment.

=head4 statusMessage

The extended status message that came back from the payment gateway when trying to process the payment.

=head4 isRecurring

A boolean indicating whether this is a recurring transaction or not. Defaults to 0.

=head4 originatingTransactionId

Most of the time this will be empty. But if this is a recurring transaction, then this will hold the id of the original transaction that started the recurrence.

=head4 notes

A text field containing notes about this transaction.
