附加内容以阻止多个子模板

Question

关于如何用树枝附加块有几个问题.答案总是使用继承和使用,然后调用parent().不知怎的,我不知道这在我的具体情况下是如何工作的:

base.html.twig

{% block content %}{% endblock %}
{% block appendable %}
{% endblock %}
{% block another_appendable %}
{% endblock %}

site.html.twig

{% extends base.html.twig %}
{% block content %}
{# Here use/include/embed, i dont know #}
{% use sub1.html.twig %}
{% use sub2.html.twig %}
{% endblock content %}

sub1.html.twig

Some content that should be directly rendered
{% block appendable %}
some stuff that should be added to appendable
{% endblock %}
{% block another_appendable %}
This content should be added to "another appendable"
{% endblock %}

sub2.html.twig

{% block appendable %}
additional stuff that should be appended
{% endblock %}

我希望sub1和sub2中的两个内容都在appendable中呈现.我怎么能实现这一目标？

我们走吧.我有同样的问题,这个解决方案对我有用:

base.html.twig

{% block content %}{% endblock %}

site.html.twig

{% extends base.html.twig %}

{% use sub1.html.twig with appendable as appendableContent, another_appendable as another_appendableContent %}

{% block content %}

    {% block appendable -%}
        {{ block('appendableContent') }}
    {% endblock %}

    {% block another_appendable -%}
        {{ block('another_appendableContent') }}
    {% endblock %}

{% endblock %}

sub1.html.twig

{% use sub2.html.twig with appendable as appendableContentAlternative %}

{% block appendable %}
    some stuff that should be added to appendable<br/><br/>

    {{ block('appendableContentAlternative') }}
{% endblock %}

{% block another_appendable %}
    This content should be added to "another appendable"<br/><br/>
{% endblock %}

sub2.html.twig

{% block appendable %}
    additional stuff that should be appended<br/><br/>
{% endblock %}

根据我的研究,这种技术被称为"水平重用",这里的文档是:
