Laravel：将字符串设置为模型的名称

Question

I´m working with polymorphic in Laravel 5.2. I want to set for the name of model string. There si code:

switch ($passport->element_type) {
            case 'Window':      
                $windows = Window::find($passport->element_id);
                break;
            case 'Floor':    
                $floor = Floor::find($passport->element_id);                    
                break;
            case 'Wall':
                $wall = Wall::find($passport->element_id);
            default:
                break;
        }
    };

You can see that variable "$passport->element_type" gives me the name of my model. I don´t want to do it with switch-case. Is it possible to do something like:

$passport->element_type::find($passport->element_id);

or how can I use the variable (element_type) as the name for model?

Answer 1

Have you tried it?

If

$passport->element_type::find($passport->element_id);

doesn't work, I know that

$type = new $passport->element_type;
$type::find($passport->element_id);

will.
