第4个按钮正在使用主键触发编辑功能并重定向到编辑页面
my_articles.html
That button in 4th is triggering the edit function with primary key and redirects to edit page
<tbody>
{% if articles %}
{% for article in articles %}
<tr class="table-active">
<th scope="row">1</th>
<td>{{ article.title }}</td>
<td>{{ article.date }}</td>
<td><a href="{% url 'articles:edit' pk=article.pk %}"><button type="button" class="btn btn-info">Edit</button></a></td>
{% endfor %}

{% else %}
<tr>
<td colspan=4 class="text-center text-danger">Oops!! You dont have any articles.</td>

推荐答案
在您的模板article_edit.html中-发布网址需要一个pk,就像传递my_articles.html模板一样,您需要传递一个pk
In your template article_edit.html - post url is expecting a pk, you need to pass a pk just like you are doing it for template my_articles.html
<div class="create-article"><form class="site-form" action="{% url 'articles:edit' pk=form.instance.pk %}" method="post" enctype="multipart/form-data">{% csrf_token %}...
这样django知道您正在编辑的文章
This way django knows which article you are editing
