我正在阅读以下文档：https ://docs.djangoproject.com/en/1.5/topics/auth/customizing/#substituting-a-custom-user-model

所以在我的settings.py中我放了：

AUTH_USER_MODEL = 'membership.User'

在我的会员应用程序 models.py 中，我有这个：

from django.contrib.auth.models import AbstractBaseUser

class User(AbstractBaseUser):
    USERNAME_FIELD = 'email'

运行 python manage.py syncdb 给了我：

FieldDoesNotExist: User has no field named 'email'

我检查 AbstractBaseUser 类源，当然该字段已定义，如您在此处看到的：https ://github.com/django/django/blob/master/django/contrib/auth/models.py#L359

怎么了？

AbstractBaseUser没有电子邮件字段，有AbstractUser。

如果您想使用电子邮件作为唯一标识符，那么您需要从 AbstractBaseUser 子类化并定义电子邮件字段unique=True并编写其他功能，例如Manager模型：

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager,\
    PermissionsMixin
from django.db import models
from django.utils.translation import ugettext_lazy as _
from django.utils import timezone
from django.utils.http import urlquote


class CustomUserManager(BaseUserManager):

    def create_user(self, email, password=None, **extra_fields):
        """
        Creates and saves a User with the given email and password.
        """
        now = timezone.now()
        if not email:
            raise ValueError('The given email must be set')
        email = CustomUserManager.normalize_email(email)
        user = self.model(email=email,
                          is_staff=False, is_active=True, is_superuser=False,
                          last_login=now, date_joined=now, **extra_fields)

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

    def create_superuser(self, email, password, **extra_fields):
        u = self.create_user(email, password, **extra_fields)
        u.is_staff = True
        u.is_active = True
        u.is_superuser = True
        u.save(using=self._db)
        return u


class User(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(_('email address'), unique=True)
    first_name = models.CharField(_('first name'), max_length=30, blank=True)
    last_name = models.CharField(_('last name'), max_length=30, blank=True)
    is_staff = models.BooleanField(_('staff status'), default=False,
        help_text=_('Designates whether the user can log into this admin '
                    'site.'))
    is_active = models.BooleanField(_('active'), default=True,
        help_text=_('Designates whether this user should be treated as '
                    'active. Unselect this instead of deleting accounts.'))
    date_joined = models.DateTimeField(_('date joined'), default=timezone.now)

    objects = CustomUserManager()

    USERNAME_FIELD = 'email'

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

    def get_absolute_url(self):
        return "/users/%s/" % urlquote(self.pk)

    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

    # define here other needed methods
    # Look at django.contrib.auth.models.AbstractUser

此外，您可能希望将此用户添加到管理页面。查看UserAdmin并重新定义它以与使用电子邮件字段作为唯一标识符的新用户模型兼容。

不幸的是，其中没有任何内容django.contrib.auth可以简单地进行子类化以获得具有

  1. 电子邮件地址代替用户名和

  2. 与其他django.contrib.auth东西很好地配合使用，比如组。

最简单的方法是复制models.py，从，到处撕掉用户名，admin.py并在它的地方输入电子邮件地址。我已经做到了，并且在几个客户项目中成功地使用了它。forms.pydjango.contrib.auth

我已经把它放在 github 和 pypi 上，所以你可以安装它

pip install django-libtech-emailuser

并查看github上的使用说明
