使用 parent() 函数并覆盖父级的子级块 [英] Using parent() function and overriding parent's children block

问题描述

我如何使用 {{ parent() }} 并覆盖它的一个子块，我找到了一些解决方案，但看起来不对，这是一个可以解释问题的示例:

How can I use {{ parent() }} and override one of its children blocks, I found some solution but it looks wrong, here is an example that may be explain the issue:

index.html.twig:

{% block wrapper %}
    <h1>title</h1>
    {% block one %}<p>Content of block one</p>{% endblock one %}
    {% block two %}<p>Content of block one</p>{% endblock two %}
{% endblock wrapper %}

new_index.html.twig:

{% extends 'index.html.twig' %}
{% block wrapper %}
    {{ parent() }}
    {% block two %}<p>NEW content of block two</p>{% endblock two %}
{% endblock wrapper %}

但是我看到第二块的内容两次(看起来很合乎逻辑).如何更新代码以修复它?

But I see the content of block two twice (and it looks logical). How can I update the code to fix it?

推荐答案

哇，解决方案很简单，只需在包装块外面写块二，块没有层次结构:)

Wow, solution is simple, just write block two outside the wrapper block, there is no hierarchy for blocks :)

new_index.html.twig:

{% extends 'index.html.twig' %}
{% block wrapper %}
    {{ parent() }}
{% endblock wrapper %}
{% block two %}<p>NEW content of block two</p>{% endblock two %}
