Question

我和Django做了一个博客。该博客可让管理员创建帖子和类别。我使用bootstrap将帖子对齐。这是我博客的主页。当帖子到达屏幕的另一端时。看下面的例子：

post1 post2 post3 post4 post5 post6 post7 post8 post9 post10 post11 post12 post 13 post14 post16。

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中，但不会显示在index.html的主页上

的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 %}

类别页面

{% extends 'base.html' %}
{% block head_title %}Viewing category {{ category.title }}{% endblock %}
{% block title %}{{ category.title }}{% endblock %}

{% block content %}
<br><br><br>
<div class="container">
{% if posts %}
<div class="row">
{% for post in posts %}
<div class="poosts col-md-4">

<p class="past"><a class="link" href="{{ post.get_absolute_url }}"><span 
class="tda"> {{post.title}}</span><br><br>{{post.body|truncatewords:13}}</a>
</p>
</div>
{% endfor %} 

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

</div>
{% endblock %}

def __str__(self):

Answer 1

您应该在views.py中尝试以下“帖子”：Blog.objects.all()

Django帖子没有在主页上显示，但在类别列表中
