Django将不会显示来自型号

Question

的文本字段我有一个登录系统，您需要登录后才能提交新帖子。我的“新邮政”页面/表格工作正常，用户提交的内容在数据库中正确发布，如何在主页上显示该内容时只显示标题和副标题（即Charfields），而没有帖子的正文文本（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 %}

Answer 1

注意你的命名。您的for循环变量名为posts（末尾有s），但您试图显示post.post_body。在某些地方，因为您使用的是posts.post_title，所以它工作正常。

要解决此问题，请在for循环中将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会失败默默不能在模板中，这也就是为什么，在展示什么评价任何表情。
