Question

EDIT: UPDATING MY QUESTION FOR MORE CLARIFICATION

==========================================================

I use MeioUpload to upload pictures. The picture location is placed in the DB users table in image as such:/img/uploads/users/img/picture34.png.

When a user is deleted, CakePHP is also accessing the physical location of this image from User.image and deleting that image.

There is no belongTo/HasMany relationship here as I do not have an image model/controller.

How can I prevent CakePHP from physically deleting this image?

==========================================================

In my application I have the option to remove a user using the admin_delete function in my users_controller.php. However, when this function is called (see following function), the image saved in the DB is also deleted. How can I prevent this function from removing the image.

function admin_delete($id = null) {

    if (!$id) {
        $this->Session->setFlash(__('Este usuario nao existe', true));
        $this->redirect(array('action'=>'index'));
    }

    if ($this->User->delete($id)) {
        $this->Session->setFlash(__('Este usuario ja foi removido', true));
        $this->redirect(array('action'=>'index'));
    }

    $this->Session->setFlash(__('Este usuario nao foi removido', true));
    $this->redirect(array('action' => 'index'));
}

Thanks,

The Meioupload behavior defines this beforeDelete method:

/**
 * Deletes all files associated with the record beforing delete it.
 *
 * @author Vinicius Mendes
 * @param $model Object
 */
function beforeDelete(&$model) {
    $model->read(null, $model->id);
    if(isset($model->data)) {
        foreach($this->__fields as $field=>$options) {
            $file = $model->data[$model->name][$field];
            if($file && $file != $options['default'])
                $this->_deleteFiles($file, $options['dir']);
        }
    }
    return true;
}

Since there is no option to don’t delete the image I think the only way is to temporary detach the behavior. Couldn’t test it but something like this could work:

function admin_delete($id = null) {
    $this->User->Behaviors->disable('MeioUpload');

    // your code

    $this->User->Behaviors->enable('MeioUpload');
}

I’m assuming the image is associated with the user model by a belongsTo/hasMany association? In this case the standard delete method has a parameter to avoid deleting of associated data, here is the definition of the delete function:

delete(int $id = null, boolean $cascade = true);

if you set cascade to false you associated image doesn’t get deleted:

if ($this->User->delete($id,false)) {
    $this->Session->setFlash(__('Este usuario ja foi removido', true));
    $this->redirect(array('action'=>'index'));
}
