保存belongsTo的Cakephp问题

我在保存belongto时遇到了问题

class Script extends AppModel {
    var $name = 'Script';
    var $belongsTo = array(
    'ScriptCatagories' => array(
        'className' => 'ScriptCatagories',
        'foreignKey' => 'script_catagories_id',

 function add_script() {
   pr($this->data);
    if (!empty($this->data)) {
        $this->Script->create();
        $this->data['Script']['script_catagories_id'] = $this->Script->scriptCategory->id;
        $this->data['Script']['user_id'] = $this->Auth->user('id');
        if ($this->Script->save($this->data)) {
            $this->Session->setFlash(__('The script has been saved', true));
             $this->redirect(array('action' => 'script_index'));
        } else {
            $this->Session->setFlash(__('The script could not be saved. Please, try again.', true));
        }
    }

     pr($scriptCatagories = $this->Script->ScriptCatagories->find('list')); 
     $this->set(compact('scriptCatagories'));
}

单击“保存”时

Array
(
[Script] => Array
    (
        [name] => fdfvvds
        [description] => dfvdfvdfvdf
        [tags] => 
     )
   )
    Array
   (
    [0] => performance
    [1] => cleanup
    )

中的问题

        $this->data['Script']['script_catagories_id'] = $this->Script->scriptCategory->id;

我需要将categoryid保存到脚本表，但我不知道如何获取它
多谢各位

首先，它没有右括号。它应该是单数ScriptCategory，也是外键script\u category\u id（只是按照惯例）。而且你拼错了分类（你有

$this->Script->scriptCategory->id；

后面的代码）

很抱歉，但在实际代码中是完整的，但在问题中我丢失了它

var $belongsTo = array(
'ScriptCatagories' => array(
    'className' => 'ScriptCatagories',
    'foreignKey' => 'script_catagories_id',
