Creating global permissions variable after user authorization in Laravel

Question

I would like to set global variable after the user is authenticated - lets call it permissions. The variable should be available in controllers and views.

What is the best way to achieve it? Now in each method I have to perform database query and check user roles which is not optimal.

I know that I can declare view::share method in appserviceprovider to pass the variable to views, but boot method is performed after the user is authenticated.

Update

I've created BaseController which extends from Controller.

BaseController:

class BaseController extends Controller {

  public $permissions;

  public function __construct() {
      $this->permissions = GroupRoles::where('id', Auth::user()->id)->first();
  }

}

Then I'm trying to access the permissions variable from UserController which extends from BaseController. Getting the trying to get access of non-object. I think it's because the BaseController constructor is contructed before the middleware.

class UserController extends BaseController {

  public function showPermissions() {
    return var_dump($this->permissions);
  }

}

The final solution

The cornerstone was to use the $this->middleware(function ($request, $next) in the BaseController.

Answer 1

Try it within the controller or create your own BaseController then extend your controllers from it and in the BaseController you can do like this

public $permissions;

public function __construct()
{
   $permissions = Permissions::all() //For example
   $this->permissions = $permissions
}

Then you can access it from every controller like this $this->permissions
