Question

我在我的应用程序fowl中使用了一个custon用户模型。当我运行syncdb或makemigrations或migrate时，我会收到LookupError。请帮忙

在settings.py我已将AUTH_USER_MODEL定义为'fowl.User'

禽/ models.py

    from django.db import models
    from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager
    from django.utils import timezone
    from django.core.mail import send_mail
    from django.utils.translation import ugettext_lazy as _

class UserManager(BaseUserManager):
    def create_user(self, email, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password):
        """
        Creates and saves a superuser with the given email, date of
        birth and password.
        """
        user = self.create_user(email,
                                password=password,
                                )
        user.is_admin = True
        user.save(using=self._db)
        return user


class User(AbstractBaseUser, PermissionsMixin):
    """
    Custom user class.
    """
    email = models.EmailField(_('email address'), unique=True, db_index=True)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)
    is_staff = models.BooleanField(_('staff status'), default=False)
    date_joined = models.DateTimeField(default=timezone.now)
    first_name = models.CharField(_('first name'), max_length=30, blank=True)
    last_name = models.CharField(_('last name'), max_length=30, blank=True)
    is_festival = models.BooleanField(default=True)

    objects = UserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    def __unicode__(self):
        return self.email

    class Meta:
        verbose_name = _('user')
        verbose_name_plural = _('users')
        abstract = True

    def get_full_name(self):
        """
        Returns the first_name plus the last_name, with a space in between.
        """
        full_name = '%s %s' % (self.first_name, self.last_name)
        return full_name.strip()

    def get_short_name(self):
        """
        Returns the short name for the user.
        """
        return self.first_name

    def email_user(self, subject, message, from_email=None, **kwargs):
        """
        Sends an email to this User.
        """
        send_mail(subject, message, from_email, [self.email], **kwargs)

    @property
    def is_festival(self):
        """Is the user a member of staff?"""
        return self.is_festival

当我运行syncdb或makemigrations时，我得到LookupError

我做错了什么？

在User班级Meta中，您设置了引发问题的abstract=True。删除它，然后运行makemigrations。

另请注意，您正在重复AbstractUser class中已存在的许多字段。你可以消除它们。

class User(AbstractBaseUser, PermissionsMixin):
    is_admin = models.BooleanField(default=False)
    is_festival = models.BooleanField(default=True)

    #The properties, methods, etc..
