// app/routes.PHP
Route::resource('CharacterController');

控制器中的相应方法是：

// app/controllers/CharacterController.PHP
public function index(){
    $characters = Character::all();
    $houses = House::all();

    return View::make('characters.index')->with(array('characters'=>$characters,'houses' => $houses));
}

最后,在视图中：

// app/views/characters/index.blade.PHP
#this fires an error:
{{ $houses[$characters->house_id]->name }}

# at the same time this gives correct result: 
{{ $houses[1]->name }}

# and this IS equal to 1:
{{ $characters->house_id }}
