- 在重写用户模型时报错：AttributeError: type object ‘UserProfile’ has no attribute ‘USERNAME_FIELD’

在重写用户模型时报错：AttributeError: type object ‘UserProfile’ has no attribute ‘USERNAME_FIELD’

models.py

- 新建用户模型UserProfile继承自AbstractBaseUser

# -*- encoding:utf-8 -*-

from __future__ import unicode_literals

from django.db import models

from django.contrib.auth.models import AbstractBaseUser

# Create your models here.

class UserProfile(AbstractBaseUser):

    nick_name = models.CharField(max_length=50, verbose_name=u"昵称", default="")

    birday = models.DateField(verbose_name=u"生日", null=True, blank=True)

    gender = models.CharField(max_length=5, choices=(("male", u"男"),("female",u"女")), default="female")

    address = models.CharField(max_length=100, default=u"")

    mobile = models.CharField(max_length=11, null=True, blank=True)

    image = models.ImageField(upload_to="image/%Y/%m", default=u"image/default.png", max_length=100)

    class Meta:

        verbose_name = u"用户信息"

        verbose_name_plural = verbose_name

    def __unicode__(self):

        return self.username1234567891011121314151617181920212223

settings.py中也设置了AUTH_USER_MODEL

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'mx_users',

]

AUTH_USER_MODEL = "mx_users.UserProfile"123456789101112

debug时报错：

AttributeError: type object 'UserProfile' has no attribute 'USERNAME_FIELD'1

最后google了一圈才发现解决办法：

答案还是得去官方文档中寻找

https://docs.djangoproject.com/en/1.9/topics/auth/customizing/

在模型中新增两行代码，即可解决

    identifier = models.CharField(max_length=40, unique=True)

    USERNAME_FIELD = 'identifier'12

如下：

class UserProfile(AbstractBaseUser):

    identifier = models.CharField(max_length=40, unique=True)

    USERNAME_FIELD = 'identifier'

    nick_name = models.CharField(max_length=50, verbose_name=u"昵称", default="")

    birday = models.DateField(verbose_name=u"生日", null=True, blank=True)

    gender = models.CharField(max_length=5, choices=(("male", u"男"),("female",u"女")), default="female")

    address = models.CharField(max_length=100, default=u"")

    mobile = models.CharField(max_length=11, null=True, blank=True)

    image = models.ImageField(upload_to="image/%Y/%m", default=u"image/default.png", max_length
