Question

我有一个登录系统，您需要登录才能提交新帖子。我的新帖子＆＃34;页面/表单工作正常，用户提交的内容已正确发布到数据库中，如何在主页上显示该内容时仅显示标题和副标题（即Charfields），并且没有帖子的正文（这是一个文本字段）。

inde.html

{% extends "blog/base.html" %}
{% block body_block %}


    <div class="left">
        {% if userposts %}
            {% for posts in userposts %}
                <div class="front-post">
                    <h2 class="post-title">{{ posts.post_title }}</h2>
                    <h3 class="post-sub-title">{{ posts.post_sub_title }}</h3>
                    <p class="post-author">{{ post.post_author }}</p>
                    <p class="post-date">{{ post.post_date }}</p>
                    <p class="post-body">{{ post.post_body }}</p>
                </div>
            {% endfor %}
        {% endif %}
    </div>


    <div class="right">
        <p>SIDE BAR</p>
    </div>


{% endblock %}

注意你的命名。您的for循环变量的名称为posts（最后带有s），但您尝试显示post.post_body。在某些地方，它正在运行，因为您正在使用posts.post_title。

要解决此问题，请在for循环的任何位置将posts重命名为post。

{% for post in userposts %}
  <div class="front-post">
      <h2 class="post-title">{{ post.post_title }}</h2>
      <h3 class="post-sub-title">{{ post.post_sub_title }}</h3>
      <p class="post-author">{{ post.post_author }}</p>
      <p class="post-date">{{ post.post_date }}</p>
      <p class="post-body">{{ post.post_body }}</p>
  </div>
{% endfor %}

Django将无声地失败任何无法在模板中评估的表达式，这就是为什么没有显示的原因。

Django不会从模型中显示文本字段
