雄辩的路线隐式绑定Laravel 5.6无法正常工作

Question

I have tried to develop an application and I'd like to use route binding, but something is wrong and I don't know what it is. Plz, look code below and help me what it is wrong.

Route

|        | PATCH    | api/v1/filial/{filial}                  |      | Genesis\Base\Filial\Controllers\FilialController@update                    | auth:api   |

Model

class Filial extends Model{

/**
 * @var string
 */
protected $table = "filiais"; ...

Controller

class FilialController extends BaseFormController{...
    public function update(FilialRequest $request, Filial $filial){
       dd($filial);
    }...

And then the output comes as a model empty. I don't know what it is wrong, parameter's, Model, Uri all these things matches. I'm using Laravel 5.6 since the beginning of this project.

Ensure you have everything setup properly, in your kernel.php you should have:

protected $routeMiddleware = [
    ...
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ...
];

You also need to ensure you have the bindings middleware in your routes:

Route::group(['middleware' => ['bindings'], function() {
    // routes
}

If that still isn't working I would opt to look into explicit route binding :

To register an explicit binding, use the router's model method to specify the class for a given parameter. You should define your explicit model bindings in the boot method of the RouteServiceProvider class:

public function boot()
{
    parent::boot();

    Route::model('filial', App\Filial::class);
}
