我知道也有类似的问题,因此我尝试了所有解决这些问题的解决方案。这是我描述的问题;
当我执行createsuperuser时,出现如下错误:
AttributeError: 'Manager' object has no attribute 'get_by_natural_key'
这是我在实现中定义UserAccountManager和UserAccount的方式。
from django.db import models
from django.contrib.auth.models import BaseUserManager, AbstractBaseUser
class UserAccountManager(BaseUserManager):
def create_user(self, email, first_name, last_name, password=None):
if not email:
raise ValueError('Email must be set!')
user = self.model(email=email, first_name=first_name, last_name=last_name)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, first_name, last_name, password):
user = self.create_user(email, first_name, last_name, password)
user.is_admin = True
user.save(using=self._db)
return user
def get_by_natural_key(self, email_):
return self.get(code_number=email_)
class UserAccount(AbstractBaseUser):
email = models.EmailField(unique=True)
first_name = models.CharField(max_length=128)
last_name = models.CharField(max_length=128)
is_active = models.BooleanField(default=True) # default=False when you are going to implement Activation Mail
is_admin = models.BooleanField(default=False)
objects = UserAccountManager
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['first_name', 'last_name']
def get_short_name(self):
return self.email
def get_full_name(self):
return self.email
def has_perms(self, perm, ob=None):
return True
def has_module_perms(self, app_label):
return True
def natural_key(self):
return self.email
@property
def is_staff(self):
self.is_admin
我在UserAccount类中设置对象如下:objects = UserAccountManager
我做错了什么?
编辑(以解决Iain Shelvington的解决方案):
在settings.py中,我有这行;
AUTH_USER_MODEL = 'accounts.UserAccount'
最佳答案
应该是objects = UserAccountManager()
