Laravel 5.7. Route model binding validation

I'd like to use sweet Laravel model binding and then run some complex validation checks on the model itself.

Something like

Route::post('/do-something/{something}', 'SomeController@store');

and

$request->validate([
    'order' => [
        new MyFirstVeryComplexRule,
        new MySecondVeryComplexRule,
        new MyThirdVeryComplexRule,
        //...
    ],
]);

I assume, that $value passed to each rule will be an instance of App\Something class.

Is is possible to achieve that?

The closest option I can think of is to pass id of a model and then run App\Some::find($value) in each rule instance, but this kills the performance and is not scalable.

Answer

No, this is not possible because of x,y,z, try a,b,c

will also be accepted.
