Hello everyone, I am having some trouble… in CMS5, I am trying to create a custom query operation… and the moment I add the operation to the schema modelConfig: DataObject without adding it to any model, I start to get a “Missing graphql file for SilverStripeSiteTree error.”
ReadByURLQuery.php:
<?php
namespace LMC\GraphQL;
use Exception;
use SilverStripe\ORM\DataObject;
use GraphQL\Type\Definition\ResolveInfo;
use GraphQL\Type\Definition\Type;
use SilverStripe\GraphQL\Schema\Interfaces\OperationCreator;
use SilverStripe\GraphQL\Schema\Field\ModelQuery;
use SilverStripe\GraphQL\Schema\Interfaces\ModelOperation;
use SilverStripe\GraphQL\Schema\Interfaces\SchemaModelInterface;
use SilverStripe\CMS\Model\SiteTree;
/**
* Scaffolds a readByURL Operation
*/
class ReadByURLQuery implements OperationCreator
{
public function createOperation(
SchemaModelInterface $model,
string $typeName,
array $config = []
): ?ModelOperation
{
$mutationName = 'read' . ucfirst($typeName) . 'ByURL';
return ModelQuery::create($model, $mutationName)
->setType($typeName)
->addArg('url', 'String!')
->setResolver([self::class, 'resolve'])
->setResolverContext([
'dataClass' => $model->getSourceClass(),
]);
}
public static function resolve(array $resolverContext = []): \Closure
{
$dataClass = $resolverContext['dataClass'] ?? null;
return function ($obj, array $args) use ($dataClass) {
if (!$dataClass) {
return null;
}
$page = DataObject::get($dataClass)
->filter('FullPath', $args['url'])->first();
if(!$page) {
throw new \Exception(sprintf(
'Page not found %s',
$this->dataObjectClass
));
}
if(!$page->canView()) {
throw new \Exception(sprintf(
'Cannot view %s',
$this->dataObjectClass
));
}
return $page;
};
}
}
I don’t understand where this is coming from, I’ve rebuilt the graphql schema of course just prior to that…
Here’s the trace from graphql ide:

Note that I am doing a bit of guesswork how to create a ModelQuery, as the only example in the v5 docs is a MutationQuery… and maybe the code above is way off
