How to generate right route in twig with dynamic sub-domain? - symfony

Question

I have a multi-tenant APP based on sub-domain that's working properly but I have an issue with generated link in Twig templates.
All the generated link are on the default sub-domain and not the current one
routes.yaml
app_customer:
resource: '../src/Controller/Customer/'
host: "{subdomain}.domain.com"
defaults:
subdomain: tenant1
requirements:
subdomain: tenant1|tenant2
SecurityController.php
class SecurityController extends AbstractController
{
/**
* #Route("/login", name="app_login", methods={"GET","POST"})
*/
public function login(AuthenticationUtils $authenticationUtils)
{
// 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,
]);
}
}
login.html.twig
<form action="{{ path('app_login') }}" method="post">...</form>
will always generate https://tenant1.domain.com/login however the current url is tenant2.domain.com

I believe it is always generating https://tenant1.domain.com/login because you have "tenant1" set as the default value for subdomain and you do not pass a different value when you call path()
Try this :
{% set currsubdomain = app.request.getHttpHost()|split('.')|first %}
<form action="{{ path('app_login', {subdomain: currsubdomain }) }}" method="post">...</form>
Or maybe just pass the whole host:
<form action="{{ path('app_login', {host: app.request.getHttpHost}) }}" method="post">...</form>
