Question

我正在开发一个带有从crud命令生成的表的项目。请参阅我的“Voorraad”实体下面的代码

index.html.twig

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

{% block body -%}
<h1>Voorraad lijst</h1>

<table class="records_list">
    <thead>
        <tr>
            <!-- <th>Id</th> -->
            <th>Product</th>
            <th>Type</th>
            <th>Fabriek</th>
            <th>Inkoopprijs</th>
            <th>Verkoopprijs
            <th>Aantal</th>
            <th>Locatie</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>
    {% for entity in entities %}
        <tr>
   <!--         <td><a href="{{ path('voorraad_show', { 'id': entity.id }) }}">{{ entity.id }}</a></td> -->
            <td>{{ entity.getProduct().getNaam() }}</td>
            <td>{{ entity.getProduct().getType() }}</td>
            <td>{{ entity.getProduct().getFabriek() }}</td>
            <td>{{ entity.getProduct().getInkoopprijs() }}</td>
            <td>{{ entity.getProduct().getVerkoopprijs() }}</td>
            <td>{{ entity.aantal }}</td>
            <td>{{ entity.getLocatie().getLocatienaam() }}</td>
            <td>

                    <a href="{{ path('voorraad_edit', { 'id': entity.id }) }}">Voorraad aanpassen</a>

            </td>
        </tr>
    {% endfor %}
    </tbody>
</table>

    <ul>
    <li>
        <a href="{{ path('voorraad_new') }}">
            Nieuwe voorraad toevoegen   
        </a>
    </li>
</ul>
{% endblock %}

我想通过“Locatie”（=位置）订购该表，以下表格。

<th>Locatie</th>

Locatie是实体“Voorraad”的外键，是实体“Locatie”的主键。我也有一个名为“产品”的权利。不幸的是，我不知道如何完成这件事。

Answer 1

在为视图提供信息的控制器中，您需要对实体进行排序;

 $this->get('doctrine')->getRepository('YourBundle\Entity\YourEntity')->findBy(array(), array('Locatie', 'ASC'));

见这里;

http://doctrine-orm.readthedocs.org/projects/doctrine-orm/en/latest/reference/working-with-objects.html

EntityRepository＃findBy（）方法另外接受排序，限制和偏移作为第二到第四参数：

我正在直截了当地回答这个问题，因为您需要提供有关您的实体和“Locatie”的详细信息。 association（entity.getLocatie（）。getLocatienaam（））

Answer 2

我认为最好的解决方案就是这个问题的答案：

symfony2 sort collection of objects by a property

使用教义实体对子元素进行排序

如何在Twig / Symfony2中按对象/表头排序表
