NameError: 'user' not defined: 试图扩展抽象用户模型 - DJANGO

Question

第一次尝试通过扩展 User 模型来创建学生用户。

问题：点击注册 btn 即登录 (btn) 而不是 重定向到主页显示以下内容：NameError at /register/ ...名称“用户”未定义

文件“E:\ifb299\tutorial2\accounts\views.py”，第 33 行，在寄存器中 Students.objects.create(user=user) NameError: name 'user' is not defined [25/Mar/2018 14:38:07] "POST /register/ HTTP/1.1" 500 67801

不太确定我做错了什么，为什么 Students.objects.create(user=user) 错了，请问我该如何解决？

Answer 1

首先，你没有将form.save()的返回值保存到变量user中。

其次，没有字段user你的模型Student。
