Question

我的代码如下所示：

模型/ user.py

from __future__ import unicode_literals
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import (
    AbstractBaseUser, PermissionsMixin,BaseUserManager
)

class UserManager(BaseUserManager):

    def _create_user(self, email, password, **extra_fields):
        """
        Creates and saves a User with the given email,and password.
        """
        if not email:
            raise ValueError('The given email must be set')
        try:
            with transaction.atomic():
                user = self.model(email=email, **extra_fields)
                user.set_password(password)
                user.save(using=self._db)
                return user
        except:
            raise

    def create_user(self, email, password=None, **extra_fields):
        extra_fields.setdefault('is_staff', False)
        extra_fields.setdefault('is_superuser', False)
        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email, password, **extra_fields):
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)

        return self._create_user(email, password=password, **extra_fields)



class User(AbstractBaseUser, PermissionsMixin):
    """
    An abstract base class implementing a fully featured User model with
    admin-compliant permissions.

    """
    email = models.EmailField(max_length=40, unique=True)
    first_name = models.CharField(max_length=30, blank=True)
    last_name = models.CharField(max_length=30, blank=True)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    date_joined = models.DateTimeField(default=timezone.now)

    objects = UserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name', 'last_name']

    def save(self, *args, **kwargs):
        super(User, self).save(*args, **kwargs)
        return self

模型/的初始化的.py

 from user import User

settings.py

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
    'django.middleware.clickjacking.XFrameOptionsMiddleware'
]



AUTH_USER_MODEL = 'dashboard.User'

在我运行python manage.py migrate之后，它会给我以下错误：

    raise ValueError("\n".join(error.msg for error in errors))
ValueError: The field admin.LogEntry.user was declared with a lazy reference to 'dashboard.user', but app 'dashboard' doesn't provide model 'user'.

是因为jwt令牌配置不正确还是用户模型？

Answer 1

您是否尝试过使用get_user_model检索用户模型？

from django.contrib.auth import get_user_model

User = get_user_model()

django自定义用户模型给了我惰性引用错误
