Cakephp версии 2.x Невозможно показать выбранное имя файла в режиме редактирования

Надеюсь, это простая проблема.

У меня установлен Cakephp MVC для загрузки изображения и сохранения его в таблице базы данных.
Index, View и Add работают как я хочу.

Однако в представлении «Правка» я могу указать, что в записи есть загруженное изображение, которое я могу сохранить для изменения.

Я не смог выяснить, что установить в атрибутах кнопки ввода файла, чтобы показать существующее имя файла.

<div class="imageEdit form">
<?php
echo $this->Form->create('VwImage', array('action' => 'edit', 'type' => 'file') );
echo $this->Form->input('image_category', array(
'options' => $partCat,
'selected' => $this->data['VwImage']['image_category'],
'type'=>'select', 'empty' => '(Choose One)'));
echo $this->Form->input('description');
echo $this->Form->input('image', array( 'value' => $this->data['VwImage']['file_name'],
'type' => 'file'));

echo $this->Form->submit('Save');
echo $this->Form->end();
?>

Код контроллера для редактирования
