Permissions User and Roles

i need some advice, basically i have a application where users can register has normal customers, and inside the dashboard there is a option to register has author for a list of categories. A customer can be many authors.

So basically after registering/subscribing has a author in the custom dashboard appears a box of his author(s) that he created and after clicking it goes to a specifc dashbboard with different menu, etc.

My only issue is when i start create the permissions, for example i created a Middleware with the name of "author", so when someone try to access these pages it must be a author.

Middleware code:

public function handle($request, Closure $next)
    {

        if(isset($request->id) && auth()->check() && count(auth()->user()->authorsProfile) > 0){
            return $next($request);
        }
        return redirect('/dashboard')->with("error","Only Authors Allowed");
    }

example:

Route::group(['middleware' => ['auth','author']], function() {
//Dashboard
Route::get('authorsarea/{id}','AuthorController@dashboard')->name('author-dashboard');
});

So the second validation i need to make is inside the controllers, i need to check based on the ID if this author id belongs to the customer/user.

example:

 public function dashboard($id)
    {

        $user = Auth::user();

        $user_author = Author::find($id);

        if($user_author->user_id != Auth::user()->id){
            return back()->with("error","This Author is not you");
        }

        //Go to dashboard
        return view('frontend.author.dashboard');
    }

I feel that pasting alwasy this code and checking if this author belongs to the user doesnt feel quite clean, is there a better way than pasting always this code in each page controller where i try to access a private area of authors?

Or event if you guys feel that there is a completelly different way in doing all of this im open.
