我不能在 django.contrib.auth.models 的用户模型中添加一些列吗？

Question

我想在 django.contrib.auth.models 的用户模型中添加生日和性别数据列。但是，我写了 forms.py 之类的

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.forms import AuthenticationForm
from .models import User

class RegisterForm(UserCreationForm):
    class Meta:
        model = User
        fields = ('username', 'email','password1','password1','birthday','sex',)
    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget.attrs['class'] = 'form-control'
        self.fields['email'].widget.attrs['class'] = 'form-control'
        self.fields['password1'].widget.attrs['class'] = 'form-control'
        self.fields['password2'].widget.attrs['class'] = 'form-control'
        self.fields['birthday'].widget.attrs['class'] = 'form-control'
        self.fields['sex'].widget.attrs['class'] = 'form-control'

当我运行代码时，django.core.exceptions.FieldError: Unknown field(s) (birthday) specified for User 错误发生。 我搜索了 Django 文档，所以我发现各种用户对象的字段是有限的，比如只有用户名、电子邮件和密码、is_staff 和 last_login 等。但是现在我想添加生日和性别数据列，我该怎么做？不能我做吗？我应该怎么写？ 现在通过一个答案，我重写了models.py

from django.db import models
from django.contrib.auth.models import User

class NewUser(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    birthday = models.DateField()
    sex = models.IntegerField()

我重写了forms.py

class RegisterForm(ModelForm):
    class Meta:
        model = NewUser
        fields = ('username', 'email','password1','password1','birthday',)
    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget.attrs['class'] = 'form-control'
        self.fields['email'].widget.attrs['class'] = 'form-control'
        self.fields['password1'].widget.attrs['class'] = 'form-control'
        self.fields['password2'].widget.attrs['class'] = 'form-control'
        self.fields['birthday'].widget.attrs['class'] = 'form-control'

我用同样的方法重写了forms.py　之前。但是我得到了一个错误django.core.exceptions.FieldError: Unknown field(s) (username, password1, email) specified for NewUser。我应该如何解决这个问题？

更新

在您的RegisterForm 中，model 应该是NewUser，您可能想要使用ModelForm。

只改form是不够的，你需要从model开始，我建议你用OneToOneField加你自己的model：

from django.contrib.auth.models import User

class Employee(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    birthday = models.DateField()
    sex = models.IntegerField()

然后您可以创建自己的form。
