class Cat extend AppModel{
   public static function getCat($medium=NULL){
       $allcat = $this->Cat->find('all', array('contain' =>false,
                'conditions' => array('Cat.c_medium' => $medium), 
                 'order' => array('Cat.c_name' => 'asc')));
       return $allcat;
   }
}

我想从default.ctp中访问此方法,Cat::getCat('eng'); 但这不起作用,请帮助我.

错误: - Fatal error: Class 'Cat' not found in C:\xampp\htdocs\app\View\Layouts\default.ctp on line 100
