问题


I'm trying to extend carts resource with one more field which should output result of Cart::getSummaryDetails call. I've extended CartCore class to add new parameter and corresponding method like this:

class Cart extends CartCore
{
    protected $webserviceParameters = [
        'fields'       => [
            'id_address_delivery' => ['xlink_resource' => 'addresses'],
            'id_address_invoice'  => ['xlink_resource' => 'addresses'],
            'id_currency'         => ['xlink_resource' => 'currencies'],
            'id_customer'         => ['xlink_resource' => 'customers'],
            'id_guest'            => ['xlink_resource' => 'guests'],
            'id_lang'             => ['xlink_resource' => 'languages'],
        ],
        'associations' => [
            'cart_rows' => [
                'resource'       => 'cart_row',
                'virtual_entity' => true,
                'fields'         => [
                    'id_product'           => ['required' => true, 'xlink_resource' => 'products'],
                    'id_product_attribute' => ['required' => true, 'xlink_resource' => 'combinations'],
                    'id_address_delivery'  => ['required' => true, 'xlink_resource' => 'addresses'],
                    'quantity'             => ['required' => true],
                ],
            ],
            'summary'   => [
                'getter'         => 'getWsSummaryDetails',
                'setter'         => false,
                'virtual_entity' => true,
            ],
        ],
    ];

    public function getWsSummaryDetails()
    {
        $result = $this->getSummaryDetails(null, true);
        unset($result['carrier']);
        unset($result['delivery']);
        unset($result['invoice']);
        return $result;
    }
}

The expected output should be something like this:

<?xml version="1.0" encoding="UTF-8"?>

                ... <!-- and so on -->
            </summary>
        </associations>
    </cart>
</carts>
</prestashop>

But I get <summary>[Array]</summary> or xml parse errors.

The another way I've tried to add cart_summary was to create CartSummary object with needed $webserviceParameters fields. But I can't get how to get values from this fields and how to associate this cart_summary object with carts resource.

Well, debug is a silver bullet. It turned out to be a bit easier to extend carts resource than I thought. First of all, there is no need to make any extra resource. The only thing we need is to list field we need and to set them getters. My extended Cart class:

class Cart extends CartCore
{
    protected $webserviceParameters = [
        'fields'       => [
            'id_address_delivery' => ['xlink_resource' => 'addresses'],
            'id_address_invoice'  => ['xlink_resource' => 'addresses'],
            'id_currency'         => ['xlink_resource' => 'currencies'],
            'id_customer'         => ['xlink_resource' => 'customers'],
            'id_guest'            => ['xlink_resource' => 'guests'],
            'id_lang'             => ['xlink_resource' => 'languages'],
        ],
        'associations' => [
            'cart_rows'    => [
                'resource'       => 'cart_row',
                'virtual_entity' => true,
                'fields'         => [
                    'id_product'           => ['required' => true, 'xlink_resource' => 'products'],
                    'id_product_attribute' => ['required' => true, 'xlink_resource' => 'combinations'],
                    'id_address_delivery'  => ['required' => true, 'xlink_resource' => 'addresses'],
                    'quantity'             => ['required' => true],
                ],
            ],
            'cart_summary' => [
                'resource'       => 'cart_summary_row',
                'virtual_entity' => true,
                'setter'         => false,
                'fields'         => [
                    'id'                        => '',
                    'is_virtual_cart'           => '',
                    'total_discounts'           => '',
                    'total_discounts_tax_exc'   => '',
                    'total_wrapping'            => '',
                    'total_wrapping_tax_exc'    => '',
                    'total_shipping'            => '',
                    'total_shipping_tax_exc'    => '',
                    'total_products_wt'         => '',
                    'total_products'            => '',
                    'total_price'               => '',
                    'total_tax'                 => '',
                    'total_price_without_tax'   => '',
                    'is_multi_address_delivery' => '',
                    'free_ship'                 => '',
                ],
            ],
        ],
    ];


    /**
     * @return array
     */
    public function getWsCartSummary()
    {
        $result = $this->getSummaryDetails(null, true);
        unset($result['carrier']);
        unset($result['delivery']);
        unset($result['invoice']);
        $result['id'] = $this->id;
        return ['cart_summary' => $result];
    }
}

WebserviceOutputBuilder doesn't suit well to deal with objects and it needs to make more complicated fields list and getters. I just needed scalar values. So I've unset carrier, delivey and invoice objects. Prestashop searches for getter getWsCartSummary() for field cart_summary by default. If you had any_other field, it would be getWsAnyOther().

The result I've got:
