我需要限制 Django 查询中的帖子数量。我试图添加一个最小值和最大值，但似乎没有任何效果。我已将 home.html 添加到代码中。

示例：我的博客中应该只有 15 篇最新的帖子。其余的可以通过单击类别按钮来查看。

主页.html：

{% extends 'base.html' %}

{% block content %}




<h1>Posts</h1>

<ul>
{% for post in object_list %}

    <li><a href="{% url 'article-detail' post.pk %}">{{post.title}}</a> 
<style>
    a {
        text-transform: capitalize;
    }
</style>
        - <a href="{% url 'category' post.category %}">{{ post.category }}</a> - <a href="{% url 'show_profile_page' post.author.profile.id %}">{{ post.author.first_name }} 
    {{ post.author.last_name }}</a> - {{ post.post_date }} <small>

        {% if user.is_authenticated %}
            {% if user.id == post.author.id %}

            - <a href="{% url 'update_post' post.pk %}">(Edit)</a>

            <a href="{% url 'delete_post' post.pk %}">(Delete)</a>
            {% elif user.id == 1 %}

            - <a href="{% url 'update_post' post.pk %}">(Edit)</a>

            <a href="{% url 'delete_post' post.pk %}">(Delete)</a>

            {% endif %}

        {% endif %}


    </small><br/>
    {{ post.snippet }}</li>
{% endfor %}
</ul>

回答

    all_objs = Post.objects.all().order_by('-id')

{% for post in object_list %}

   {% if forloop.counter <= 15 %}

       <h4>{{obj}} #or anything really that is meant to be shown on the home page.</h4>

   {% endif %}

{% endfor %}
