我有维护控制器来获取学生和教师的属性，并在一个视图中进行，但值来自学生和教师模型不保存。

型号：学生

public function tableName()
{
    return 'student';
}

        array('lastname, firstname, middlename, course, email', 'length', 'max'=>32),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('studentid, lastname, firstname, middlename, course, year, cellphonenumber, email', 'safe', 'on'=>'search'),
    );
}

public function relations()
{
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
