Django1.5自定义用户profile可谓简单很多，编写自己的model类MyUser，MyUser至少要满足如下要求：
- 必须有一个整型的主键
- 有一个唯一性约束字段，比如username或者email，用来做用户认证
- 提供一种方法以“short”和“long"的形式显示user，换种说法就是要实现 get_full_name和get_short_name方法。
一：在project中创建一个account app
django-admin startapp account
二：自定义MyUser
实现自定义User模型最简单的方式就是继承AbstractBaseUser，AbstractBaseUser实现了User的核心功能，你只需对一些额外的细节进行实现就可以了。可以看看AbstractBaseUser的源码：
@python_2_unicode_compatible
class AbstractBaseUser(models.Model):
password = models.CharField(_('password'), max_length=128)
last_login = models.DateTimeField(_('last login'), default=timezone.now)
is_active = True
REQUIRED_FIELDS = []
class Meta:
abstract = True
def get_username(self):
"Return the identifying username for this User"
return getattr(self, self.USERNAME_FIELD)
def __str__(self):
return self.get_username()
def natural_key(self):
return (self.get_username(),)
def is_anonymous(self):
"""
Always returns False. This is a way of comparing User objects to
anonymous users.
"""
return False
def is_authenticated(self):
"""
Always return True. This is a way to tell if the user has been
authenticated in templates.
"""
return True
def set_password(self, raw_password):
self.password = make_password(raw_password)
def check_password(self, raw_password):
"""
Returns a boolean of whether the raw_password was correct. Handles
hashing formats behind the scenes.
"""
def setter(raw_password):
self.set_password(raw_password)
self.save(update_fields=["password"])
return check_password(raw_password, self.password, setter)
def set_unusable_password(self):
# Sets a value that will never be a valid hash
self.password = make_password(None)
def has_usable_password(self):
return is_password_usable(self.password)
def get_full_name(self):
raise NotImplementedError()
def get_short_name(self):
raise NotImplementedError()
AbstractBaseUser只有get_full_name和get_short_name方法没有实现了。接下来我们就通过继承AbstractBaseUser来自定义User模型叫MyUser：
class MyUser(AbstractBaseUser, PermissionsMixin):
username = models.CharField('username', max_length=30, unique=True,
db_index=True)
email = models.EmailField('email address',max_length=254, unique=True)
date_of_birth = models.DateField('date of birth', blank=True, null=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username']
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.')
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
objects = MyUserManager()
- USERNAME_FIELD ：作为用户登录认证用的字段，可以usename，或者email等，但必须是唯一的。
- REQUIRED_FIELDS ：使用createsuperuser命令创建超级用户时提示操作者输入的字段
- is_staff ：判断用户是否可以登录管理后台
- is_active ：判断用户是否可以正常登录
三：自定义MyUserManager
同时要为MyUser自定义个一个manager，通过继承BaseUserManager，提供creat_user和create_superuser方法。
class MyUserManager(BaseUserManager):
def create_user(self, username, email=None, password=None, **extra_fields):
now = timezone.now()
if not email:
raise ValueError('The given email must be set')
email = UserManager.normalize_email(email)
user = self.model(username=username, email=email,
is_staff=False, is_active=True, is_superuser=False,
last_login=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.is_superuser = True
u.save(using=self._db)
return u
四：指定AUTH_USER_MODEL
覆盖默认的AUTH_USER_MODEL，在settings.py文件中增加：
AUTH_USER_MODEL = 'user.MyUser'
五：注册MyUser
在account模块下创建admin.py，添加如下代码把MyUser模型注册到admin中：
from django.contrib import admin
from user.models import MyUser
admin.site.register(MyUser)
总结：实现自定义的User模型在Django1.5足够简单方便，根据自己需求继承AbstractBaseUser就可以了。当然如果你想了解更多关于Django 自定义用户模型相关内容，官方文档告诉你更多更好的完好
