Exclude "attributes" section from response about json-api-php HOT 1 CLOSED

Same issue here. It seems as if this was intended to be implemented, but there is a missing conditional in: \Tobscure\JsonApi\Resource::toArray().

This is a quick fix by adding the if (!$this->isIdentifier()) before the $array['attributes'] = $this->getAttributes(); statement ~line 75. It checks if the constructor was intended to be a resource-identifier-object (i.e., you fed the constructor the id (string), and not an array/object of data).

With that in place, you can get the right format (and still with the original serializer):

$participants = ["1", "2", "3", ...];
$collection = new Collection($participants, new ParticipantSerializer());
$document = new Document($collection);
return response($document, 200);

That way, we avoid duplication of serializer classes for the identifiers/resources of the same types.
