Overwrite Default Queries

CoreShop Headless provides a simple way to overwrite the default queries. There are two ways to overwrite the default queries.

Extend Inputs of a Query

CoreShop Headless uses a similar approach as Symfony Form to extend the inputs of a query. You can extend an existing Input Type by creating a new Input Type Extension. For example:

<?php

declare(strict_types=1);

namespace CoreShop\Bundle\HeadlessBundle\InputType;

use Symfony\Component\OptionsResolver\OptionsResolver;

class AddToOrderInputItemTypeExtension implements DataHubInputTypeExtensionInterface
{
    public function __construct(
        private InputTypeFactoryInterface $inputTypeFactory,
    ) {
    }

    public function extendType(array $type, array $options): ?array
    {
        $type['fields']['orderItem']['type'] = $this->inputTypeFactory->buildType(OrderItemInputType::class, ['allow_units' => true]);

        return $type;
    }

    public function getExtendedTypes(): ?array
    {
        return [
            AddToOrderInputType::class,
        ];
    }

    public function configureOptions(OptionsResolver $optionsResolver): void
    {
    }
}

You also must register the Input Type Extension as a service and tag it with coreshop_headless.input_type_extension:

services:
  CoreShop\Bundle\HeadlessBundle\InputType\AddToOrderInputItemTypeExtension:
    arguments:
      - '@CoreShop\Bundle\HeadlessBundle\InputType\InputTypeFactoryInterface'
    tags:
      - { name: coreshop.datahub.input_type_extension }

Since it only makes sense to then also extend the Command Handler, you can also do that by decorating the existing one:

services:
  App\CoreShop\Headless\CommandHandler\AddToOrderHandler:
    decorates: 'CoreShop\Bundle\HeadlessBundle\CommandHandler\AddToOrderHandler'

Your Input Arguments are then passed in the last argument of the Command called $args
