I would like to catch an event (for example creating ) and attach a global scope only if the model is creating. So far I've done: Event::listen('eloquent.creating*', function ($event, $model) { /** * @var Model $eloquentModel */ $eloquentModel = $model[0]; $eloquentModel->addGlobalScope(new AuthorizationScope($event)); }); The scope constructor is called, but the apply method from it is never fired

问题 As in the basic Laracasts.com tutorial (Laracast 5.7 from scratch) I'm trying to use the following methods public function show(prototypes $prototypes) parameter to construct a view. However my view is created correctly but $prototypes is null. The route works well( /prototypes/1/edit ) and I ensured that a prototype object with the id 1 exists. I found some older solution which stated to use something like (integer $id) as parameter but this leads to some more code. It should work like this:
