Symfony 4 Как взять параметр со страницы

У меня есть страница

    <style>
        .IMG img {  max-width: 500px;  max-height: 500px; width: 100% }
    </style>
        <h2>Article {{ article.title }}</h2>
        <div class="card bg-success text-white">
            <div class="card-body">
                <div>Title: {{ article.title }}</div>
                    <div>Author: {{ article.author }}</div>
                    <br>
                <div>Time: {{ article.created|date("F jS \\a\\t g:ia") }}</div>
                <br>
                <div>Content: <br> {{ article.content }}</div>
                {%   if(article.image) %}
                <div class="IMG">File:<br> <img src="{{ asset('/uploads/' ~ article.image)}}" alt="кукапук"> </div>
                {% endif %}
                <button><a class="nav-link" href="{{ path('subscribers', {'article': article.id }) }}">Подписаться</a></button>
                <div class="text-white bg-white"><a href="{{ path('update_article', {'id': article.id }) }}">Edit</a></div>
                <div class="text-white bg-white"><a href="{{ path('article_delete', {'article': article.id }) }}">Delete</a></div>
            </div>
        </div>

На странице есть кнопка, <button><a class="nav-link" href="{{ path('subscribers', {'article': article.id }) }}">Подписаться</a></button>, которая относиться к другому контроллеру, как взять параметр id с этой страницы и перенести его в контроллер. То есть мне нужно взять параметр "article.id" и впихнуть его в контроллер

Контроллер в который мне нужно записать id

    <?php

    namespace App\Controller;

    use App\Entity\Article;
    use App\Entity\Subscribers;
    use App\Entity\User;
    use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
    use Symfony\Component\HttpFoundation\Request;
    use Symfony\Component\Routing\Annotation\Route;

    class SubscribersController extends AbstractController
    {
        /**
         * @Route("/subscribers/", name="subscribers")
         */
        public function sub()
        {
            $article= new Article();
            $em =$this->getDoctrine()->getManager();
            $post= $this->getDoctrine()->getRepository(Article::class)->find($article->getId());
            $sub=new Subscribers();
            $Us= $this->getUser();
            $em->getRepository(User::class)->find($Us->getId());
            $sub->setUsers($Us);
            $sub->setAuthor($article->getUser());
            $em->persist($sub);
            $em->flush();
            return $this->render('subscribers/index.html.twig', [
                'controller_name' => 'SubscribersController'
            ]);
        }
    }

Мне нужно, чтобы я мог записать в setAuthor article.id ,который был взят со страницы выше

Контроллер странице на которой у меня кнопка
