Question

见下面的固定代码

我正在使用django 1.8开发我的第一个网页项目。我的网页有一个部分，其中包含产品菜单和显示基于所选菜单项的不同视图的列。

首先，我尝试了一种方法，其中每个菜单按钮都分配了一个onclick js函数，用于更改块的内容。我想我会将每个产品的html代码写入单独的文件，js函数将读取该文件。我得到了部分工作，但感觉有点粗略。

我的第二种方法是基于使用django模板但我作为一个初学者遇到了一些错误我无法弄清楚到底是什么问题。如果有人能够确定我做错了什么，或者告诉我动态更改内容的正确方法，我将非常感激。

我目前遇到的错误：

Answer 1

我认为错误在于产品功能中的渲染没有得到正确使用的<product_name>。它表明它所拥有的参数（它正在尝试的<product_name>）都没有。因此，您在产品功能中要做的就是尝试确保您真正获得<product_name>。

如何在django上动态更改块的内容？
