How can I see only one user’s associated data?

Solution for How can I see only one user’s associated data?
is Given Below:

I got lists of clients, services and associated services: the last list has names of clients and services, specs about services like contract date & their price. But I want to see specific data depending on the user I choose, for example: if I choose an user, i can see the service he contracted and the same information that has the table. Another question about it is about the access, how can I put the button in each user column? I only made the table page in yii like that:

$this->title="Asociados";
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="asociados-index">

    <h1><?= Html::encode($this->title) ?></h1>

    <p>
        <?= Html::a('Crear Asociados', ['create'], ['class' => 'btn btn-success']) ?>
    </p>

    <?php // echo $this->render('_search', ['model' => $searchModel]); ?>

    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yiigridSerialColumn'],

            //'id',
            'cliente',
            'servicio',
            'fechaContrato',
            'fechaVencimiento',
            'precio',

            ['class' => 'yiigridActionColumn'],
        ],
    ]); ?>

    <p><a class="btn btn-primary" href="http://c2111406.ferozo.com/report/web/index.php?r=servicios%2Findex">Ver servicios</a></p>


</div>

And this is the access from the clients index page:

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yiigridSerialColumn'],

        'id',
        'nombre',
        'apellidoPaterno',
        'apellidoMaterno',
        'RFC',
        //'fechaAlta',
        //'fechaDeNacimiento',
        //'domicilio',
        //'numeroTelefonico',
        //'correoElectronico',

        ['class' => 'yiigridActionColumn'],
    ],
]); ?>

<p><a class="btn btn-primary" href="http://localhost/report/web/index.php?r=asociados%2Findex">Ver servicios asociados</a></p>
