I want to reuse the logic of binding a {slug} to a model, in several resources.

Route::bind("slug", function($slug) {
	$item=Item::where('slug', $slug)->first();
	
	if($item)
	{
		return $item;	
	}
	else {
		App::abort(404);
	}
});

How can I reuse this code to use it for other resources like posts, ...

Should I define a function like this

function slug_model_binder($slug, $Model) {
	$model=$Model::where('slug', $slug)->first();
	
	if($model)
	{
		return $model;	
	}
	else {
		App::abort(404);
	}	
}

and use several calls to Route::bind() for different models like this:

Route::bind('item', function($slug) {
	return slug_model_binder($slug, 'Item');
});

Route::bind('post', function($slug) {
	return slug_model_binder($slug, 'Post');
});

Or can $route param of the binder callback help me to determine the current model?

what's the common practice for this functionality?
