Django：通过自定义模板标签用户输入修改数据？(Django: modifying data with user input through custom template tag?)

 是否可以通过Django中的自定义模板标记修改数据？ 更具体地说，我有一个名为Shift的模型，其数据我想以日历形式显示。 我认为使用自定义包含标签是最好的方法，但我也希望用户能够点击班次并购买/出售班次（从而修改数据库）。 我的猜测是你不能用包含标签来做这件事，但如果我要从头开始编写不同类型的自定义模板标签，这可能吗？ 如果是这样，你能指导我一些资源来解决如何编写这样的标签吗？ 
 
 先谢谢你。 

Is it possible to modify data through custom template tag in Django? More specifically, I have a model named Shift whose data I want to display in a calendar form. I figured using a custom inclusion tag is the best way to go about it, but I also want users to be able to click on a shift and buy/sell the shift (thus modifying the database). My guess is that you can't do this with an inclusion tag, but if I were to write a different type of custom template tag from the ground up, would this be possible? If so, can you direct me to a few resources that address how to write such a tag?
 
Thank you in advance.
