在树枝中访问段落的子字段

Question

如何访问段落字段的子字段。

对于我的旋转木马，我制作了一个英雄形象旋转木马＆＃34;段落，然后对于田地，我做了另一个分段＆＃34;英雄形象旋转木马领域＆＃34;我分配到第一个。这让我有了多张幻灯片，它在后端完美运行。

现在我想在树枝模板中设置样式。

我可以直接访问第一个，第二个等子字段，如下所示： content.field_hero_image_c_fields.0['#paragraph'].field_hero_image_c_content 但我需要在循环中拥有它。现在的问题是，当我做类似的事情时：

{% for item in content.field_hero_image_c_fields %}
    {{ item }}
{% endfor %}

它确实获取了我的字段，还有其他默认字段，如uuid，field_name等。

我如何只为我需要的字段访问和制作循环？

感谢您的任何建议！

Answer 1

这种方法对我有用

{% for item in content['#node'].field_myparagraphfield_items %}
....
<img class="carousel-image-fullsize" src="{{ file_url( item.entity.field_picture_item_image_main[0].entity.uri.value | image_style("my_carousel_image_style") )}}">
....
{% endfor %}

段落中的字段将在for循环中找到item.entity.field_picture_item_image_main。不是最容易理解的事情！
