Laravel错误：ErrorException缺少参数1？

Question

I am using Laravel 4 and I am getting ERROR: when I visit admin/profile/: Missing argument 1 for AdminController::getProfile()

My AdminController code :

public function getProfile($id) {
    if(is_null($id)) Redirect::to('admin/dashboard');
    $user = User::find($id);
    $this->layout->content = View::make('admin.profile', array('user' => $user));
}

My routes.php :

Route::controller('admin', 'AdminController');

My admin/profile (blade) view :

@if(!is_null($user->id)) 
{{ $user->id }} 
@endif 

How could I fix this? I want when they go to admin/profile without ($id) to redirect to dashboard.

Try setting a default null value to $id like this :

public function getProfile($id = null) {
   ...
}
