[Insight] Object parameters should be type hinted - in src/Helper/EmbeddedListHelper.php, line 134

[alterphp]

Violation reported by SensioLabInsight. We call getId method on unknwon object.
=> method may not exist.

Is it possible to get identifiers without parsing each of related object (from collection ?) ?

@rimi-itk any idea ?

in src/Helper/EmbeddedListHelper.php, line 134

The parameter entity, which is an object, should be typehinted.

                // ManyToMany association
                elseif (isset($assoc['joinTable'])) {
                    $relatedItems = PropertyAccess::createPropertyAccessor()->getValue(
                        $parentEntity, $parentEntityProperty
                    );
                    $itemIds = $relatedItems->map(function ($entity) {
                        return $entity->getId();
                    });

                    return ['entity.id' => $itemIds->toArray()];
                }

@alterphp, I'm not sure if/how we can get ids without getting (full) objects from the collection, but we should definitely clean up the code and not make assumptions on the existence of the getId method:

$fieldName = $assoc['joinTable']['joinColumns'][0]['referencedColumnName'];
$assocFieldPart = 'entity.'.$fieldName;
$accessor = PropertyAccess::createPropertyAccessor();
$relatedItems = $accessor->getValue(
    $parentEntity, $parentEntityProperty
);
$itemIds = $relatedItems->map(function ($entity) use ($accessor, $fieldName) {
    return $accessor->getValue(
        $entity,
        $fieldName
    );
});

return [$assocFieldPart => $itemIds->toArray()];

This matches the code in the OneToMany part which makes perfect sense.

In a very old post on https://groups.google.com/forum/m/#!topic/symfony2/BVgT2vmLbto Christophe Coevoet (stof) claims that ”Getting the identifier will not initialize the proxy anymore in 2.2”, but I have not been able to verify this. I will investigate further.
