【问题描述】：
我收到此错误，我正在尝试使用 web.py 创建一个简单的 Web 项目，不幸的是，当我尝试注册用户时，我收到了错误，我已经尝试更改属性但无法解决问题
File "C:\Users\Pippo\Anaconda3\lib\site-packages\web\utils.py", line 75, in __getattr__
return self[key]
KeyError: 'name'
During handling of the above exception, another exception occurred:

我已经检查了文件（Main.py、RegistrationModel.py 和 Register.HTML），但没有找到错误。

session_data = session._initializer
render = web.template.render("Views/Templates", base = "Main",
globals={'session': session_data, 'current_user': session_data["user"]})
class PostRegistration:
def POST(self):
data = web.input()
reg_model = RegisterModel.RegisterModel()
reg_model.insert_user(data)
return data.username

任何想法为什么我有这个错误？
感谢您的帮助！

您的
data对象似乎没有name变量。另外，您能否编辑您的帖子，使错误出现在三次勾号中，使其看起来像代码，并添加一些细节？我试图编辑它，但不知道要添加哪些细节。 -
在
RegistrationModel.py你使用data.name这会产生问题。似乎data没有字段name。在你的表格中，我看不到<input>和name="name"，而是name="display_name"。试试data.display_name而不是data.name -
@Manson Caiby 首先感谢编辑！
-
@furas 非常感谢您的帮助，问题实际上出在 register.html 我只是将
name = "display_name"更改为name = "name"，现在它可以工作了！非常感谢！
