創建Django自定義用戶模型時的關係錯誤

Question

我一直在關注this guide以在Django中創建自定義用戶模型。我是Django的新手，並且在試圖按照第8步使用south構建遷移時遇到了一系列的四個錯誤。

的錯誤是：

auth.user: Accessor for m2m field 'groups' clashes with related m2m field 'Group.user_set'. Add a related_name argument to the definition for 'groups'. 
auth.user: Accessor for m2m field 'user_permissions' clashes with related m2m field 'Permission.user_set'. Add a related_name argument to the definition for 'user_permissions'. 
member.customuser: Accessor for m2m field 'groups' clashes with related m2m field 'Group.user_set'. Add a related_name argument to the definition for 'groups'. 
member.customuser: Accessor for m2m field 'user_permissions' clashes with related m2m field 'Permission.user_set'. Add a related_name argument to the definition for 'user_permissions'. 

我理解的是多對多的關係問題，我相信由PermissionsMixin引起的。雖然我不是100％確定的。

這是我的自定義模式：

class CustomUser(AbstractBaseUser, PermissionsMixin): 
    email = models.EmailField(_('email address'), max_length=254, 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' 
    REQUIRED_FIELDS = [] 

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

    def get_full_name(self): 
     full_name = '%s %s' % (self.first_name, self.last_name) 
     return full_name.strip() 

    def get_short_name(self): 
     return self.first_name 

    def email_user(self, subject, message, from_email=None): 
     send_mail(subject, message, from_email, [self.email]) 

而定製的用戶管理：

class CustomUserManager(BaseUserManager): 
    def _create_user(self, email, password, is_staff, is_superuser, **extra_fields): 
     now = timezone.now() 

     if not email: 
      raise ValueError('The given email must be set') 

     email = self.normalize_email(email) 
     user = self.model(email=email, is_staff=is_staff, is_active=True, is_superuser=is_superuser, last_login=now, date_joined=now, **extra_fields) 
     user.set_password(password) 
     user.save(using=self._db) 
     return user 

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

    def create_superuser(self, email, password, **extra_fields): 
     return self._create_user(email, password, True, True, **extra_fields) 

Models.py進口：

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

我也創建了自定義窗體和自定義管理員位，就像教程一樣，但不相信他們與這個問題有關。如果需要，我很樂意將它們包含在內。

我已經嘗試設置AUTH_USER_MODEL = 'member.CustomUser'到AUTH_USER_MODEL = 'auth.User'爲好。

我被卡住了，在這最後一晚已經花了很長時間了。我會非常感謝任何建議。

您必須在settings.py中聲明AUTH_USER_MODEL。你的情況：

AUTH_USER_MODEL = 'member.customuser'
