Add a Twig Context Factory — Sylius Stack

Ask the user if not provided:

• The resource (ModelName) and the target operation (typically Show, Index, Create, Update).
• The variable(s) to add and where the value comes from (related entities, repository call, aggregated counts, external service…).
• The factory class name. Default: {Operation}{ModelName}ContextFactory (e.g. ShowBookContextFactory).

If the user only needs to change the template path of an operation, do not create a factory — use the template: option on the operation instead:

new Show(template: 'book/custom_show.html.twig')

1. Create the context factory

src/Twig/Context/Factory/{FactoryName}.php

<?php

declare(strict_types=1);

namespace App\Twig\Context\Factory;

use Sylius\Resource\Context\Context;
use Sylius\Resource\Metadata\Operation;
use Sylius\Resource\Twig\Context\Factory\ContextFactoryInterface;

final class {FactoryName} implements ContextFactoryInterface
{
    public function __construct(
        private ContextFactoryInterface $decorated,
        // TODO: inject the services used to build your extra variables (repositories, services…)
    ) {
    }

    public function create(mixed $data, Operation $operation, Context $context): array
    {
        return array_merge($this->decorated->create($data, $operation, $context), [
            // TODO: add your extra variables here, e.g.:
            // 'related_books' => $this->bookRepository->findRelatedTo($data),
            // 'stats' => $this->statsService->for($data),
        ]);
    }
}

The decorated default factory is kept in the constructor so the existing context (resource, {model_snake}, form, operation, resource_metadata, …) remains available.

2. Wire the factory on the operation

Edit src/Entity/{ModelName}.php:

use App\Twig\Context\Factory\{FactoryName};

new Show(twigContextFactory: {FactoryName}::class),

3. Use the new variables in the template
