CakePHP 3 - How to automatically show form errors for several new objects?

Question

I am trying to use any automatic error checking and display processing for a form using multiple objects.

The user can dynamically create several new objects through the UI form. Data is routed through newEntities():

$this->MyModel->newEntities($data);

The first part of the problem that I have is that in order to check whether it was not possible to check on any of the entities, I have to do this manually, checking each object:

$errors = false;
foreach ($entities as $entity) {
    if ($entity->errors()) {
        $errors = true;
        break;
    }
}
if (!$errors) {
    // Save...

Does Cake provide anything out of the box that allows you newEntities()to check if you could not verify on any of your entities? If not, then it doesn’t matter ...
