我正在使用Kohana 3.有谁知道为什么param('controller')结果为NULL.

路由:

Route::set('default', '(<controller>(/<action>(/<id>)))')
->defaults(array(
    'controller' => 'page',
    'action'     => 'index',
));

网址: http://localhost/application/page/index/1

参数调用:

$param = Request::instance()->param('controller');
echo Kohana::debug($param); //results: NULL
$param = Request::instance()->param('action');
echo Kohana::debug($param); //results: NULL
$param = Request::instance()->param('id');
echo Kohana::debug($param); //results: 1

我正在使用ORM Auth模块,很难弄清楚如何做到这一点.我试过这个案子:

$user = ORM::factory('user', $id);
$user->roles->delete_all();

并得到错误 ErrorException [ Fatal Error ]: Call to undefined method Database_Query_Builder_Delete::join()

然而$user->roles->find_all();,正是我想要的.
