-/**
- * Prevents a record from being deleted when deletion would result in orphaned related records; if deletion is prevented, an explanatory error message is stored in the model's attribute $deletionError.
- *
- * Example: A user has written many posts. Now somebody tries to delete the user - which would result in orphaned posts with no user! So this behavior prevents deletion of the user.
- *
- * Notice: This behavior has only an effect when 'dependent' is set to false (otherwise the records are all deleted anyway and no orphans would be left behind).
