Symfony login form redirect according to user role

Question

I've used the maker bundle to create a standard login form. When the user has successfully logged in it calls function onAuthenticationSuccess to redirect to the new page.

public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
    {         
        return new RedirectResponse($this->urlGenerator->generate('app_homepage'));      
    }

However, I would like to redirect to different pages depending on what role the user has. I would like to do something like:

if ($this->security->isGranted('ROLE_STANDARD_USER')) {
    return new RedirectResponse($this->urlGenerator->generate('app_homepage')); 
}

if ($this->security->isGranted('ROLE_SYS_ADMIN')) {
    return new RedirectResponse($this->urlGenerator->generate('app_ADMINpage')); 
}

But the error I'm getting is Undefined property: App\Security\LoginFormAuthenticator::$security

Many thanks in advance for the help.

I didn't have much to go by, but it seems that the default implementation of the LoginFormAuthenticator does not request the AuthorizationChecker.

You can fix this by injecting an AuthorizationChecker into your class using the constructor. Example of how dependency injection works

Seeing as you have used the maker bundle, it is safe to assume you have autowiring turned on for your services, meaning that the Symfony kernel will automagically do all the rest of the work
