I am not sure what exactly are u asking but if you want to make routes for every entity of category, you can do easily something like category/{id} in routes so its than something like:

Route::get('/category/{id}', function () {
    return view('category@show');
});

It is explained in this video from 6th minute: https://laracasts.com/series/laravel-from-scratch-2017/episodes/11

Hope this will help. Let me know.

I meant that i didn't declare "category" word in my routes. In this case was executed this route:

'<controller:\w+>/<id:\d+>' => '<controller>/view',

I suppose it would looks like:

Route::get('/{controller}/{id}', function () {
    return view('{controller}@show');
});

I havent tried that yet but I think it is possible in the same way as I mentioned with ID if laravel supports more vars in url. Did you try it?
