permission users

@tykus Thank you for your answer, where i put this line.

Gate::define('view_user_interfaces', fn (User $user) {
	return in_array($user->role, ['admin', 'super_admin']);
});

You can add it to the boot method in app/Providers/AuthServiceProvider.php

@tykus i get this error. ParseError syntax error, unexpected token "{", expecting "=>"

  public function boot()

    {

        $this->registerPolicies();

 

        Gate::define('view_user_interfaces', fn (User $user)

        {

        return in_array($user->role->name, ['Admin', 'Super Admin']);

       });

    }

}

@tykus help please :'(

Sorry, fixed above. I started writing a short Closure, and changed to a long format:

Gate::define('view_user_interfaces', function (User $user) {
    return in_array($user->role->name, ['Admin', 'Super Admin']);
});

or

Gate::define('view_user_interfaces', fn (User $user) => in_array($user->role->name, ['Admin', 'Super Admin']));

@tykus That work , but i get now this error

Error Call to a member function can() on null in UserController

Do you have an authenticated user; it would seem not?

@tykus yes i am authenticated

How are you using can inside the UserController action?

@tykus i'm using can inside function index in the user controller.

Can you actually show the code?

@tykus this is the code

public function index(User $user)
    {
        
        if (auth()->user()->can('view_user_interfaces', $user)) {
        $nbr = DB::table('users')->count();
        $users = User::with('role')->get();
        return view('users.index' , [ 'users'=> $users]);
        }
    }

@soo this line

$nbr = DB::table('users')->count();

is redundant.

@automica this line count how many users . show the number of users in the interface. why he is redundant? :(

@soo because you arent passing it to the view.

if you want to, add it to

  return view('users.index' , [ 'users'=> $users,'nbr'=> $nbr]);

@automica he work for me whithout adding .

how are you using $nbr in your blade if you arent passing that in at the end of your method?

@automica yes but he work for me he show how much i have users . this is not the problem. the problem is permission not work for me :'(

@tykus what does mean?

it means you arent logged in.

if (auth()->user()

relies on auth() but as you're not logged in you can't check it.

you can add an addition check for auth and bail your method if its not present,

public function index(User $user)
    {
		if(!auth()){
			return redirect('/'); // bail if you arent logged in.
		}
        
        if (!auth()->user()->can('view_user_interfaces', $user){
			return redirect('/'); // bail if you don't have permission;

		}
	
        $users = User::with('role')->get();
        return view('users.index' , [ 'users'=> $users]);
  
    }

hello @tykus , he show me this error.
