Python Django帖子未显示在主页上，但显示在类别列表中

我和Django写了一个博客。博客允许管理员创建帖子和类别。我使用bootstrap来对齐相邻的帖子。 这是我博客的主页。当柱子到达屏幕的另一端时。请看下面的示例：

邮政1邮政2邮政3邮政4邮政5邮政6邮政7邮政8邮政9邮政10邮政11邮政12邮政13邮政14邮政16。

post 16

不会显示在主页上，但如果您转到其类别，它将显示在类别列表上，但不会显示在主页index.html上

index.html

{% extends 'base.html' %}

{% block content %}
{% if categories %}
<div class="tab">
{% for category in categories %}
<button class="tablinks"><a href="{{ category.get_absolute_url }}">{{ 
category.title }}</a></button>
{% endfor %}
{% else %}
<p>There are no posts.</p>
{% endif %}

</div>
<br><br><br>
<div class="container ">
{% if posts %}
<div class="row ">
{% for post in posts %}
 <div class="poosts col-md-2">
 <p class="past"><a class="link" href="{{ post.get_absolute_url }}"><span 
class="tda"> {{post.title}}</span><br><br><span class="postbody">
{{post.body|truncatewords:13}}</a></span></p>
    </div>
    {% endfor %} 

{% else %}
    <p class="text-center">There are no posts.</p>
</div>
{% endif %}


</div>
{% endblock %}

您应该尝试在views.py中打印

Category.objects.all（）

，然后在索引中打印

Category.objects.all（）

，并用输出进行响应。在主页上，它只显示5篇文章。您在views.py中的意思是什么output@Nawaf您使用

Blog.objects.all（）[：5]

将其限制为5篇文章。

      posted = models.DateTimeField(db_index=True, auto_now_add=True)
