User对象是认证系统的核心。用户对象通常用来代表网站的用户，并支持例如访问控制、注册用户、关联创建者和内容等。在Django认证框架中只有一个用户类，例如超级用户(‘superusers’)或(‘staff‘)用户只不过是相同用户对象设置了不同属性而已。
username
用户名,必需字段。30个字符或更少，可以包含 _, @, +, . 和 - 字符。
first_name
可选。 30 characters or fewer.
last_name
可选。 30 characters or fewer.
email
邮箱,可选。 Email address.
password
密码,必需。Django不是以明文存储密码的，而是存储哈希值。
groups
用户组。Many-to-many relationship to Group
user_permissions
用户权限。Many-to-many relationship to Permission

groups = models.ManyToManyField(Group, verbose_name=_(‘groups‘), blank=True, help_text=_(‘The groups this user belongs to. A user will ‘ ‘get all permissions granted to each of ‘ ‘their groups.‘), related_name="user_set", related_query_name="user")user_permissions = models.ManyToManyField(Permission, verbose_name=_(‘user permissions‘), blank=True, help_text=_(‘Specific permissions for this user.‘), related_name="user_set", related_query_name="user") |
is_staff
Boolean。决定用户是否可以访问admin管理界面。默认False。
is_active
Boolean。 用户是否活跃,默认True。一般不删除用户，而是将用户的is_active设为False。
is_superuser
Boolean。默认False。当设为True时，用户获得全部权限。

def has_perm(self, perm, obj=None): """ Returns True if the user has the specified permission. This method queries all available auth backends, but returns immediately if any backend returns True. Thus, a user who has permission from a single auth backend is assumed to have permission in general. If an object is provided, permissions for this specific object are checked. """ # Active superusers have all permissions. if self.is_active and self.is_superuser: return True # Otherwise we need to check the backends. return _user_has_perm(self, perm, obj) |
last_login
上一次的登录时间，为datetime对象，默认为当时的时间。

user.last_login = timezone.now() |
date_joined
用户创建的时间
is_anonymous()
是否是匿名用户。
is_authenticated()
用户是否通过验证，登陆。
get_full_name()
返回first_name plus the last_name, with a space in between.
get_short_name()
返回first_name.
set_password(raw_password)
设置密码。
check_password(raw_password)
验证密码。
get_group_permissions(obj=None)
返回用户组权限的集合。
get_all_permissions(obj=None)
返回用户所有的权限集合。
has_perm(perm, obj=None)
用户是否具有某个权限。perm的格式是 "<app label>.<permission codename>".
has_perms(perm_list, obj=None)
用户是否具有权限列表中的每个权限。
由于User对象的密码不是明文存储的，所以创建User对象时与通常的Model create不同，需用内置的create_user()方法。

>>> from django.contrib.auth.models import User>>> user = User.objects.create_user(‘john‘, ‘lennon@thebeatles.com‘, ‘johnpassword‘)# At this point, user is a User object that has already been saved# to the database. You can continue to change its attributes# if you want to change other fields.>>> user.last_name = ‘Lennon‘>>> user.save() |
当然也可以在admin界面中添加用户。

$ python manage.py createsuperuser --username=joe --email=joe@example.com |
