SQL Error:未知列'数组'cakephp 1.3

我正在使用https://github.com/dilab/CakePHP-Photo-Behavior上找到的CakePHP-Photo-Behavior，并收到以下错误。

SQL错误:1054:'字段列表'中未知列'数组' [CORE'cake'libs'model'datasources'dbo_source.php, line 684]

查询:INSERT INTO photos (title, description, photo_dir, photo, school_id, user_id, is_slider, modified, created) VALUES ('skjg'， 'lkhg'， "， Array, 1,1,1， '2013-04-12 01:14:09'， '2013-04-12 01:14:09')

模型:

var $actsAs = array('Photo'=>array(
                    'dir'=>array('upload_directory'),
                    'file_field'=>array('photo'),
                    'file_db_file'=>array('photo'),
                    'thumb'=>array(true),
                    'thumb_size'=>array(array("100x100"))
));

视图:

<?php echo $this->Form->create('Photo', array('type' => 'file')); ?>
<?php echo $this->Form->input('Photo.title'); ?>
<?php echo $this->Form->input('Photo.description', array('type' => 'textarea', 'rows' => 3)); ?>
<?php echo $this->Form->input('Photo.photo', array('type' => 'file')); ?>
<?php echo $this->Form->input('Photo.photo_dir', array('type' => 'hidden')); ?>
<?php echo $this->Form->end(__('Upload', true));?>

控制器:

function admin_add_slider() {
    debug($this->params);
    if (!empty($this->data)) {
        //set the school id
        $session_school_id = $this->Session->read('Userinfo.currentSchoolid');
        $session_user_id = $this->Session->read('Userinfo.id');
        $this->data['Photo']['school_id'] = $session_school_id;
        $this->data['Photo']['user_id'] = $session_user_id;
        $this->data['Photo']['is_slider'] = 1;
        $this->Photo->create();
        if ($this->Photo->save($this->data)) {
            $this->Session->setFlash(__('The Photo has been saved', true));
            $this->redirect(array('action' => 'view_slider'));
        } else {
            $this->Session->setFlash(__('The Photo could not be saved. Please, try again.', true));
        }
    }
}

调试:

data] => Array
    (
        [Photo] => Array
            (
                [title] => skjg
                [description] => lkhg
                [photo_dir] => 
                [photo] => Array
                    (
                        [name] => PLDMonth6Student_img_2.jpg
                        [type] => image/jpeg
                        [tmp_name] => C:'xampp'tmp'phpBA8C.tmp
                        [error] => 0
                        [size] => 42085
                    )
            )
    )

表:id, title, description, small, large, is_slider, created, modified, school_id, user_id, photo, photo_dir

谢谢罗伯特。
