如何解决如何在Django中修复此搜索栏错误？
我正在尝试在python中的博客中创建搜索栏，但收到以下错误：找不到带有参数'（'，）'的'article-detail'。尝试了1个模式：['app1 / article /（？P [0-9] +）$']，但我不确定为什么，所以这是代码，以便您可以看到这里发生了什么：>

谢谢！
解决方法
{% for post in results %}
<li><a href="{% url 'app1:article-detail' post.pk %}">{{sym}}</a> -
{% if user.is_authenticated %}
<small><a href="{% url 'app1:updatepost' post.pk %}">Edit</a></small><small>
<a href="{% url 'app1:deletepost' post.pk %}">- Delete</a>
</small></li>
{% endif %}
<a href="{% url 'app1:article-detail' post.pk %}">
这里的“ post”没有从db声明/上下文/检索，这就是为什么您出错的原因。
