我正在尝试按照教程操作，当我运行makemigrations时出现此错误，但是在教程中，他们没有得到错误。
这是教程：https://www.codingforentrepreneurs.com/blog/how-to-create-a-custom-django-user-model/
这是我在视频中24:59得到的错误： django.core.exceptions.FieldError：为CustomUser指定的未知字段（用户名）。这是完整的追溯：

以下是我模特中的相关要点：
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
# Create your models here.
class UserManager(BaseUserManager):
def create_user(self, email, password=None, is_active=True, is_staff=False, is_admin=False):

)
return user
class CustomUser(AbstractBaseUser):
email = models.EmailField(max_length=255, unique=True)
# full_name = models.CharField(max_length=255, blank=True, null=True)
is_active = models.BooleanField(default=True) #can login

# confirm = models.BooleanField(default=False)
# confirmed_date = models.DateTimeField(default=False)
USERNAME_FIELD = 'email'
#USERNAME_FIELD and password are required by default

我的forms.py文件：
from django.contrib.auth import get_user_model
#^returns user model that is currently active in this project
from django.contrib.auth.forms import UserCreationForm
class UserCreateForm(UserCreationForm):
#^make sure that class name is not same name as import
class Meta:
fields = ('username', 'email', 'password1', 'password2')
model = get_user_model()
#^when users sign up, this is what they will have access to
def __init__(self,*args,**kwargs):
super().__init__(*args, **kwargs)
self.fields['username'].label = 'Display Name'
#^if project was twitter,
self.fields['email'].label = "Email Address"
我在settings.py文件中有这个：
AUTH_USER_MODEL = 'accounts.CustomUser' # changes the built-in user model to ours
感谢任何建议或指示！
答案 0 :(得分：0)
可能在CustomUser您正在使用的用户名字段中，您在模型中没有{{1}}
