我正在将管理站点中的图像上传到模型的imagefield中。我已经对settings.py和urls.py文件进行了必要的更改,并在我的项目中添加了媒体目录。尽管图像显示在管理站点中,但是在渲染模板时出现“图像属性没有与之关联的文件”错误。
这是我的文件:

<meta charset="utf-8">

{% if user_list %}
<ol>
{% for user in user_list %}
<li> User Info</li>

<li>First Name:{{user.f_name}}</li>
<li>Last Name:{{user.l_name}}</li>
<li>Email:{{user.email}}</li>
