NoReverseMatch at / Reverse for 'entry_detail' with arguments '()' and keyword arguments '{'slug': ''}' not found

Question

我在这里翻阅了很多标题，但没有找到解决问题的确切答案 错误指向 {% url "entry_detail" slug=object.slug %}... 这里是 home.html

{% extends 'base.html' %}
{% block blog_entries %}
 <a href="{% url "entry_detail" slug=object.slug %}">
<figure>
            <img src="{{ MEDIA_URL }}{{ object.image }}" />
            <svg viewBox="0 0 180 320" preserveAspectRatio="none"><path d="M 0 0 L 0 182 L 90 126.5 L 180 182 L 180 0 L 0 0 z "/></svg>
                    <figcaption>
                        <h2>{{ object.title }}</h2>
                        <button>Read</button>
                    </figcaption>
        </figure>
 </a>
{% endblock %}

尝试...将 slug 作为位置参数传递到模板中。

{% url 'entry_detail' object.slug %}
