【问题描述】:
我正在使用 django-mptt 库来构建类别树。当我把下面的代码放在我的模板中时,我得到了这个错误。
index.html
{% load mptt_tags %}{% load mptt_tags %}
<ul class="root">
{% recursetree nodes %}
<li>
{{ node.name }}
{% if not node.is_leaf_node %}
<ul class="children">
{{ children }}
</ul>
{% endif %}
</li>
{% endrecursetree %}
</ul>
这是我得到的错误。
