链接两个控制器get()cakephp

I would like to join two controllers. I have a controller Articles with a view function :

public function view($id = null)
    {
       $article = $this->Articles->get($id, [
            'contain' => []
        ]);
        $this->set('article', $article);
        $this->set('_serialize', ['article']);
    }

Each article has an associated user. So I have a controller Users. Now I can have the user_id for the article (in database). Is it possible to access the username in the User table with the user_id in the Articles table? With a get() function.

For example I know how to do it with find() :

$this->set('articles', $this->Articles->find('all')->contain(['Users']));

But is it possible with get()? For a particular article.

Thanks!

    if you have username field in users table:

    class UsersTable extends Table
    {
    
        public function initialize(array $config)
        {
            $this->displayField('username');
    
        }
    }
    

    Articles table

    class ArticlesTable extends Table
    {
    
        public function initialize(array $config)
        {
            $this->belongsTo('Users', [
                'foreignKey' => 'user_id',
                'joinType' => 'INNER'
            ]);
        }
    }
    

    In your Articles controller:

    public function view($id = null)
    {
       $article = $this->Articles->get($id, [
            'contain' => ['Users']
        ]);
        $this->set('article', $article);
        $this->set('_serialize', ['article']);
    }
    

    in your articles view

    <?= $article->has('user') ? $this->Html->link($article->user->username, ['controller' => 'Users', 'action' => 'view', $article->user->id]) : '' ?>
