Laravel Nova how to overwrite the nova LoginController - laravel

Question

My project requires a username rather than email. I had this working in Laravel 5.8 and Nova v2.1.0. After upgrading to L 6.x N 2.6.1 everything broke. So I started over with clean L 6.x and N 2.6.1 install.
Now I want to customize the login but I do not want to edit any Nova Package scripts as before.
I've added this code to nova/Http/Controllers/LoginController.php and all works as expected.
public function username()
{
return 'username';
}
When I add the code to App/Nova/Http/Controller/LoginController.php (a copy of the original) the login still requires an email address. Or is using the original file in nova.

Answer 1

this is what i do on my end
i override the App\Http\Controllers\Auth\LoginController.php from
class LoginController extends Controller
to
class LoginController extends \Laravel\Nova\Http\Controllers\LoginController
if you want to use username or email on the login page you have to add this.
this method will determine how the user input they credential
public function username()
{
$login = \request()->input("email");
$field = filter_var($login, FILTER_VALIDATE_EMAIL) ? 'email' : 'username';
\request()->merge([$field => $login]);
return $field;
}
because the user can login using email or username but the default login from nova only have 1 input box. have to add this to display if the user input wrong username or that username did not exist
protected function sendFailedLoginResponse(Request $request)
{
throw ValidationException::withMessages([
'email' => [trans('auth.failed')],
]);
}
on my controller i have add other method to determine if the user is admin or able to access the backend or if the user is still active.
protected function authenticated(Request $request, $user)
{
if($user->isSuperAdmin()) {
return redirect(config('nova.path'));
}
if($user->can('backend')) {
return redirect(config('nova.path'));
}
return redirect('/');
}
by adding method to check user is active i need to add this method to check if the user can login
private function activeUser($username)
{
$user = User::where($this->username(), $username)->first();
if($user) {
return $user->active;
}
return false;
}
public function login(Request $request)
{
$active = $this->activeUser($request->only($this->username()));
if(! $active) {
return $this->sendFailedLoginResponse($request);
}
return parent::login($request);
}
hope this helps
