django user模块改写

示例一:继承AbstractBaseUser,AbstractBaseUser只有三个字段password,last_login,is_active,以及需要复习的两个方法

def get_full_name(self):
        raise NotImplementedError()

def get_short_name(self):
        raise NotImplementedError()

改写例子如下:

import re
from time import timezone
from django.contrib.auth.models AbstractBaseUser, BaseUserManager
from django.core import validators
class UserManager(BaseUserManager):

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

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

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


class Users(AbstractBaseUser):
    username = models.CharField(_('username'), max_length=30, unique=True,
        help_text=_('少于30个字符组成'),validators=[
            validators.RegexValidator(re.compile('^[w.@+-]+$'), _('Enter a valid username.'), 'invalid')
        ])
    email = models.EmailField(_('email address'), blank=True)
    is_staff = models.BooleanField(default=False, verbose_name='系统管理员')
    is_teacher = models.BooleanField('是否是教师', default=False)
    is_student = models.BooleanField('是否是学校', default=False)
    is_school_manager = models.BooleanField('是否是学校管理员', default=False)
    is_college_manager = models.BooleanField('是否是学院管理员', default=False)
    date_joined = models.DateTimeField(_('date joined'), default=0)

    objects = UserManager()
    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email']

    class Meta:
        verbose_name = "用户"
        verbose_name_plural = "用户"

    def get_full_name(self):
        return self.username + "-" + self.email

    def get_short_name(self):
        return self.username

嫌麻烦直接添加字段的写法,但是会带来冗余的字段,例如first_name,last_name

再在settings里配置AUTH_USER_MODEL = "profiles.KarmaUser"

配置外键的例子:
