Question

我有一个Gecko捆绑包，它在index.html.twig文件中循环显示数据库中的所有壁虎，效果很好，没问题。

我想要做的只是显示与他们相同的用户ID的壁虎，它们等于当前用户的ID。

索引文件如下：

{% extends '::base.html.twig' %}

{% block body -%}
    <h1>Gecko list</h1>

    <table class="records_list">
        <thead>
            <tr>
                <th>Id</th>
                <th>Name</th>
                <th>Aquisitiondate</th>
                <th>Morph</th>
                <th>Sex</th>
                <th>Genetics</th>
                <th>Bio</th>
                <th>Bred</th>
                <th>Hatchling</th>
                <th>Clutch</th>
                <th>Actions</th>
            </tr>
        </thead>
        <tbody>
        {% for entity in entities %}
            <tr>
                <td><a href="{{ path('gecko_show', { 'name': entity.name }) }}">{{ entity.name }}</a></td>
                <td>{{ entity.name }}</td>
                <td>{% if entity.aquisitionDate %}{{ entity.aquisitionDate|date('Y-m-d H:i:s') }}{% endif %}</td>
                <td>{{ entity.morph }}</td>
                <td>{{ entity.sex }}</td>
                <td>{{ entity.genetics }}</td>
                <td>{{ entity.bio }}</td>
                <td>{{ entity.bred }}</td>
                <td>{{ entity.hatchling }}</td>
                <td>{{ entity.clutch }}</td>
                <td>
                <ul>
                    <li>
                        <a href="{{ path('gecko_show', { 'name': entity.name }) }}">show</a>
                    </li>
                    <li>
                        <a href="{{ path('gecko_edit', { 'name': entity.name }) }}">edit</a>
                    </li>
                </ul>
                </td>
            </tr>
        {% endfor %}
        </tbody>
    </table>

        <ul>
        <li>
            <a href="{{ path('gecko_new') }}">
                Create a new entry
            </a>
        </li>
    </ul>
    {% endblock %}

我如何限制观点？

编辑2：

这来自Gecko实体：

    /**
     * @ORM\ManyToOne(targetEntity="Breedr\UserBundle\Entity\User", inversedBy="geckos")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
     */
    protected $user;

Answer 1

class GeckoController extends Controller
{

    /**
     * Lists all Gecko entities.
     *
     * @Route("/", name="gecko")
     * @Method("GET")
     * @Template()
     */
    public function indexAction()
    {
        $em = $this->getDoctrine()->getManager();
        $user = $this->getUser();
        $entities = $em->getRepository('BreedrGeckoBundle:Gecko')->findBy('user' => $user->getId());

        return array(
            'entities' => $entities,
        );
    }

Answer 2

我们必须在View之前获取用户，因此我们可以通过

获取它

$user = $this->getUser();

这里描述

{{3}}

下一步是按用户对象

从存储库中获取数据

按用户对象我预先

$entities = $em
        ->getRepository('BreedrGeckoBundle:Gecko')
        ->findBy(array('user' => $user), array()
    );

我认为它应该有用。

在Symfony2中仅显示与当前用户ID相同的结果
