Python Django用户表单don'；不能在数据库上保存

我已经创建了一个Model、Form、View和register.html，但我的表单没有保存在数据库中，也没有创建新用户。怎么了

遵循代码

models.py

我想知道如何保存此数据，为什么

save（）

方法不起作用，以及如何在DD-MM-YYYY中格式化日期并显示迷你日历

---

谢谢。

您不应该覆盖有效的。您应该在

clean

方法中处理所有验证逻辑；您的主要问题是您不能从ModelForm继承，但也不能重写

is\u valid（）

，您应该定义

clean.*

方法。我不知道如何做。你有什么例子吗？谢谢
