十月cms博客组件currentCategorySlug无法通过宏

如何解决十月cms博客组件currentCategorySlug无法通过宏

我正在使用博客类别列表组件来显示带有子类别的类别。这是部分代码：

{% import _self as list %}
{% macro render_cats(categories) %}
{% import _self as list %}
{% for category in categories %}
{% set postCount = category.post_count %}
<li class="{{ category.slug == currentCategorySlug ? 'active' }}">
    <a class="" href="{{ category.url }}">{{ category.name }}</a>
    {% if postCount %}
    <span class="">
        {{ postCount }}
    </span>
    {% endif %}
</li>
{% if category.children|length > 0 %}
<ul>
    {% set categories=category.children %}
    {% set currentCategorySlug=currentCategorySlug %}
    {{ list.render_cats(categories) }}
</ul>
{% endif %}
{% endfor %}
{% endmacro %}

<div class="">
    <h3 class="">Categories</h3>
    {% if blogCategories.categories|length > 0 %}
    <ul class="">
        {% set categories = blogCategories.categories %}
        {% set currentCategorySlug = blogCategories.currentCategorySlug %}
        {{ list.render_cats(categories) }}
    </ul>
    {% else %}
    <p>No categories were found.</p>
    {% endif %}
</div>

除了 currentCategorySlug 实现之外，一切正常。似乎 currentCategorySlug 不能通过宏。请有任何想法。
