Please forgive for asking, i have been working on my websites login/registration pages for some time and finally have both working seemingly flawlessly, my next task is access control so i can do some work on my forum without the need to load my SSH and make database changes.

My Composer.JSON for a list of packages i have already

"require": {
    "php": "^7.1.3",
    "ext-iconv": "*",
    "doctrine/doctrine-migrations-bundle": "^2.0",
    "knplabs/knp-markdown-bundle": "^1.7",
    "sensio/framework-extra-bundle": "^5.1",
    "symfony/asset": "^4.0",
    "symfony/console": "^4.0",
    "symfony/flex": "^1.1",
    "symfony/form": "^4.0",
    "symfony/framework-bundle": "^4.0",
    "symfony/maker-bundle": "^1.1",
    "symfony/orm-pack": "^1.0",
    "symfony/profiler-pack": "^1.0",
    "symfony/security-bundle": "^4.0",
    "symfony/translation": "^4.0",
    "symfony/twig-bundle": "^4.0",
    "symfony/validator": "^4.0",
    "symfony/yaml": "^4.0"
},
"require-dev": {
    "sensiolabs/security-checker": "^4.1",
    "symfony/dotenv": "^4.0",
    "symfony/web-server-bundle": "^4.0"

The problem i have is that my login form auto outputs 'ROLE_USER' when the database returns an empty array, however i am unclear on how i can add an object to the database JSON as i need the 'ROLE_ADMIN' string.

I understand that i could add an admin user to memory but i would like to depend solely on the database having something typed out in a doc on my root server dosent feel right to me (for some reason)

I have checked the symfony docs and looked around on here and not found anything that jumps out at me as helpful.

I would like to grant a user (me) 'ROLE_ADMIN' while all other users still get the 'ROLE_USER' that 'getRoles()' returns. my firewall already has hierarchy set up Admin inherits user so i shouldnt have trouble locking myself out of other pages.

i already have a few counts of access control implemented as shown bellow

../config/packages/security.yaml
...
access_control:
     - { path: ^/admin, roles: ROLE_ADMIN }
     - { path: ^/profile, roles: ROLE_USER }

And

../templates/forum/index.html.twig
...
{%  if is_granted('ROLE_ADMIN') %}
<li><a href="{{ path('page_admin') }}">Admin</a></li>
{% endif %}
...

Here i will drop all my controller/entity info for you guys -*all of my registration/authentication files are generated with maker-bundle

../securityController
namespace App\Controller;

use App\Form\UserType;
use App\Entity\User;
use App\Form\RegistrationFormType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;

class SecurityController extends AbstractController
{
...
Registration function
...

/**
 * @Route("/forum/login", name="app_login")
 */
public function login(AuthenticationUtils $authenticationUtils): Response
{
    // get the login error if there is one
    $error = $authenticationUtils->getLastAuthenticationError();
    // last username entered by the user
    $lastUsername = $authenticationUtils->getLastUsername();

    return $this->render('security/login.html.twig', ['last_username' => $lastUsername, 'error' => $error]);
}

Entity

    // For example : return new RedirectResponse($this->urlGenerator->generate('some_route'));

Thanks in advance, any ideas are welcome
