这些是代码，它们返回错误： 当我运行 python manage.py makemigrations
命令时，为用户指定了未知字段（密码 1、密码 2）。我自定义了用户模型，并将其命名为
RemittanceUser
，继承自
AbstractUser。在我的
RemittanceUser模型中，我定义了
password1和
password2字段。然而，Django 似乎无法找到这些字段。
错误原因：
如回溯所示，您正在使用User
中的
RegisterForm模型：
class RegisterForm(forms.ModelForm):
class Meta:
model = User # Here you are using the User model for the RegisterForm
fields = ['username', 'email', 'new_password1', 'new_password2']
但是，您的 User
模型没有字段
new_password1和
new_password2。相反，它有
username
、
email、
password、
first_name、
last_name和
phone_number。
class User(models.Model):
username = models.CharField(max_length=255)
email = models.EmailField(unique=True)
password = models.CharField(max_length=128)
first_name = models.CharField(max_length=255)
last_name = models.CharField(max_length=255)
phone_number = models.CharField(max_length=10)
解决方案
默认的 User
模型已经几乎拥有您想要的一切。如果您只想向其中添加
phone_number，一种方法是创建另一个类（配置文件），然后执行
OneToOneField将其连接到默认的
User模型，如此处所述，或者可能更好，使用您的自定义用户模型，并按照已给出的链接中显示的方式进行设置。
settings.py文件中添加
AUTH_USER_MODEL变量：
AUTH_USER_MODEL = 'app_name.UserModelName'
例如：
AUTH_USER_MODEL = 'account.User'
>>> python manage.py makemigrations
>>> python manage.py migrate
>>> python manage.py runserver
forms.py文件中导入用户模型：
from django.contrib.auth import get_user_model
User = get_user_model()
class RegisterForm(forms.ModelForm):
class Meta:
model = User
fields = ['username', 'email', 'new_password1', 'new_password2']
