我在基本模板中使用exading呈现页面时遇到问题，它只显示在没有css或js的html中。以下是显示的内容：img
我正在努力理解这个问题，但它似乎不合逻辑，因为它是相同的实现
这是我的小页面：
{% extends 'base-back.html.twig'%}
{% block title %}Edit DossierEmprunteur{% endblock %}
{% block body %}
<h1>Edit DossierEmprunteur</h1>
{{ include('dossier_emprunteur/_form.html.twig', {'button_label': 'Update'}) }}
<a href="{{ path('dossier_emprunteur_index') }}">back to list</a>
{{ include('dossier_emprunteur/_delete_form.html.twig') }}
{% endblock %}
这是我的模板库：

在其他页面中，它可以正确渲染，但在编辑页面中没有
因为您使用的是相对路径，所以当您的URL获得额外级别时，文件将不会加载。
