ORM afterCreate afterUpdate toArray

What I am trying to achieve: After creating or updating a record (MySQL), I want to index it in ElasticSearch. The data that I am updating or creating, has many relations with other tables. I have a custom toArray() method that retrieves data from relations and merge with toArray() from the current model.

My problem (or is something that I am missing) is that if I try to do something like this:

public function afterCreate() 
{
    $data = $this->toArray();
    // ... code, code, code
    $client->index($data);
}

I get an exception regarding the relations. So for now, I can store the data in ES, by doing this:

public function addAction()
{
    // ...
    if ($last_record_id = $this->persistent->get('es_last_record_id')) {
        $data = Record::findFirstById($last_record_id);
        // ...
        $client->index($data);
    }
    // ...
}

public function createAction()
{
    // ...
    if (true === $record->create()) {
        $this->persistent->set('es_last_record_id', $record->getId());
    }
}

I don't necessarily complain about this approach, but there might be a problem when I need to do conditional operations. For example implement a business rule that will delete a record from ES if that record becomes inactive. Anyway, my question is related to "toArray" and "afterCreat/afterUpdate" . Anyone had similar problems ?
