Question

我有一对多的关系。一个景点可以有许多吸引力的图像。吸引力 - 表格中有来自桌子吸引力的外键ID。

我尝试使用以下控制器功能获取图像：

public function attractionIndexAction( $id )
{
    $attractionRepo = $this->getDoctrine()
        ->getRepository( "RowocoAllgemeinBundle:Attraction")
        ->find( $id );

    $attractionImagesRepo = $this->getDoctrine()
        ->getRepository( "RowocoAllgemeinBundle:AttractionImages" )
        ->find( $attractionRepo );

    return $this->render("RowocoAllgemeinBundle:Attraction:attraction.html.twig",
            array(
                "attraction"        => $attractionRepo,
                "attractionImages"  => $attractionImagesRepo
            )
    );
}

在html.twig中，我尝试查看结果：

{% for image in attraction.attractionImages %}
<li data-thumb="/attractionimages/{{ image.folder }}/thumb/{{ image.filename }}">
    <img class="img-responsive" src="/attractionimages/{{ image.folder }}/{{ image.filename }}" />
</li>
{% endfor %}

Repo有结果，但我无法在树枝文件中查看它。

这是教义xml：

我猜您的图片不在attraction中，因为您使用数组键attractionImages将其作为单独的对象传递。尝试：

{% for image in attractionImages %}
<li data-thumb="/attractionimages/{{ image.folder }}/thumb/{{ image.filename }}">
    <img class="img-responsive" src="/attractionimages/{{ image.folder }}/{{ image.filename }}" />
</li>
{% endfor %}

如何从一个对象获取相关图像
