如何使用HTML->；链接以链接到另一个表

我正在尝试设置一个链接，以便从users表中查看用户。我希望它出现在文章模板的索引文件中。

我尝试过使用：

$this->Users->Html->link($current->username, ['action' => 'view', $current->id]) ?>

和：

$this->$userstable->Html->link($current->username, ['action' => 'view' $current->id]) ?>

这是索引文件：

<div class="col-lg-8">
        <div class="panel panel-default">
            <div class="panel-heading">
                <h4 style="float:left;">Users</h4>
                <a href="http://localhost:8765/users/add"><Button class="btn btn-primary add-article">Add User</Button></a>
            </div>
            <table>
                <tr>
                    <th>Id</th>
                    <th>Userame</th>
                    <th>Role</th>
                    <th>Joined</th>

                </tr>
            <!-- Here's where we loop through our $articles query object, printing out article info -->
                <?php foreach ($userstable as $current): ?>
                <tr>
                    <td><?= $current->id ?></td>
                    <td>
                        <?= $this->Html->link($current->username, ['action' => 'view', $current->id]) ?>
                    </td>
                    <td>
                        <?= $current->role?>
                    </td>
                    <td>
                        <?= $current->created->format(DATE_RFC850) ?>
                    </td>
                    <td>
                        <?= $this->Form->postLink(
                            'Delete',
                            ['action' => 'delete', $current->id],
                            ['confirm' => 'Are you sure?'])
                        ?>
                        <?= $this->Html->link('Edit', ['action' => 'edit', $current->id]) ?>
                    </td>

                </tr>
                <?php endforeach; ?>
            </table>
        </div>
    </div>

这是控制器：

public function index()
{

    $this->paginate = [
    'contain'=>['Categories']
    ];
    $articles = $this->paginate($this->Articles);
    $this->set('articles', $this->Articles->find('all'));
    $this->set(compact('articles'));
    $this->set('_serialize', ['articles']);
    $article_count = $this->Articles->find('all')->count();
    $this->set('article_count',$article_count );
    /*$author_count = $this->Articles->find('all')
        ->distinct(['Articles.user_id'])
        ->count('user_id');
    $this->set('author_count',$author_count );*/
    $this->loadModel('Categories');
    $categoryCount = $this->Categories->find('all')->count();
    $this->set('categoryCount',$categoryCount );
    $this->loadModel('Users');
    $userstable = $this->Users->find('all');
    $this->set('userstable',$userstable );
    $usersCount = $this->Users->find('all')->count();
    $this->set('usersCount',$usersCount );
    $authorCount= $this->Users->find('all')->where(['role' => 'author'])->count();
    $this->set('authorCount',$authorCount );
    $adminCount= $this->Users->find('all')->where(['role' => 'admin'])->count();
    $this->set('adminCount',$adminCount );
    $subCount= $this->Users->find('all')->where(['role' => 'admin'])->count();
    $this->set('subCount',$subCount );
    $this->loadModel('Views');
    $views = $this->Views;
    $query = $views->find('all')->limit(7)->order(['date' => 'DESC']);;
    $results = $query->all();
    $data = $results->toArray();
    $results = $query->toArray();
    $result1 = $results[6]['amount'];
    $this->set('result1',$result1 );
    $result2 = $results[5]['amount'];
    $this->set('result2',$result2 );
    $result3 = $results[4]['amount'];
    $this->set('result3',$result3 );
    $result4 = $results[3]['amount'];
    $this->set('result4',$result4 );
    $result5 = $results[2]['amount'];
    $this->set('result5',$result5 );
    $result6 = $results[1]['amount'];
    $this->set('result6',$result6 );
    $result7 = $results[0]['amount'];
    $this->set('result7',$result7 );
    $date1 = $results[6]['date'];
    $this->set('date1',$date1 );
    $date2 = $results[5]['date'];
    $this->set('date2',$date2 );
    $date3 = $results[4]['date'];
    $this->set('date3',$date3 );
    $date4 = $results[3]['date'];
    $this->set('date4',$date4 );
    $date5 = $results[2]['date'];
    $this->set('date5',$date5 );
    $date6 = $results[1]['date'];
    $this->set('date6',$date6 );
    $date7 = $results[0]['date'];
    $this->set('date7',$date7 );


}
