Question

我有一个简单的Web界面，可在我们公司的数据库中显示设备的资产编号。我在数字Deploy和Return旁边有一个可点击的链接。我想发生的事情是，当某人单击Deploy时，该特定设备的资产编号被添加到列表中（最终是用于打印的csv文件），以及其必需的型号和序列号。

如何使可点击链接执行一个函数，该函数将其旁边的那个特定资产编号，在数据库中搜索其型号和序列号并将它们添加到列表中？

我的想法是，我可以单击一堆资产上的Deploy，并将它们放在适合打印的部署工作表上。我是Django的新手，并且我一直在使用Mozilla教程作为该网站的骨架，但是现在我要取消一点保留了。谢谢！
