所以我想在我的主页上使用我Product模型的图像字段中的数据显示多个图像。前提是每次我添加带有图像的新产品时，它都会生成带有新图像的新li标签。
然后我希望当用户点击主页上的图像时，它会显示在模型窗口中，其中包含URL中产品的slug名称，其中显示模板中的其余Product信息在模型窗口中。
那么有人可以帮助指导我如何实施这个解决方案吗？
这是我到目前为止所做的：
谢谢！

您可以在MEDIA_URL中设置settings.py，然后使用<img src="{{ MEDIA_URL }}{{ product.image.url }}" />

恕我直言，您遇到了如何访问视图中内容的问题。如果您使用的是表单视图，则应通过{{ form....}}（例如{{form.image.url}}）获取数据。
如果您有可用的对象且尚未重新定义其别名，则应通过{{ object.... }}获取该对象。
