django - Django 仅使用硬编码路径加载图像

Question

因此，只有当我硬编码了 img 标签的 src 值时，Django 才会加载图像。这是我的带有硬编码图像路径的模板（工作正常）：

{% load static %}
{% block content %}

<p>{{ product.title_text}}</p>
<p>{{ product.description_text }}</p>
<p>{{ image.image }}</p>
    <img src="{% static 'my_app/images/product_images/some_image.jpg' %}" alt="{{ image.name }}">

{% endblock %}

但是，如果我将图像路径更改为实际上是相同路径的动态变量，则什么都不会显示。没有错误，只是没有图像。

<img src="{% static image.image %}" alt="{{ image.name }}">

这是settings.py。也许它会有所帮助。
