我的主页上有帖子列表，这些帖子是帖子详细视图的链接。链接工作正常，但当我进入DetailView时，列表就不可见了--我必须回到主页选择其他帖子。显示帖子列表的元素位于base.html，正确地将对象列表传到home.html，而在post_detail.html中列表是空的。
base.html
<body>
<div>
<ul>
<li>
<a href="{% url 'blog-home' %}"> home</a>
</li>
<li>
<a> items</a>
<ul>
{% for post in posts %}
<li>
<a href="{% url 'post-detail' post.id %}"> {{ post.title }}</a>
</li>
{% endfor %}
</ul>
</li>
</ul>
</div>
<di>
{% block content %}
{% endblock content %}
</div>
</body>
首页.html
{% extends "blog/base.html" %}
{% block content %}
{% for post in posts %}
<div>
<a href="#">{{post.title}}</a>
<p>{{post.content}}</p>
<p>{{post.date_posted}}</p>
</div>
{% endfor %}
{% endblock content %}
post_detail.html
{% extends "blog/base.html" %}
{% block content %}
<div>
<a href="#">{{object.title}}</a>
<p>{{object.content}}</p>
</div>
{% endblock content %}

你必须覆盖你的DetailView的上下文，它只显示当前实例的数据。
class PostDetailView(DetailView):
model = Post
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['other_posts'] = Post.objects.all()
return context
