自定义用户认证系统

Django 自带的用户认证系统已经可以满足大部分的情况，但是有时候我们需要某些特定的需求。Django 支持使用其他认证系统、也可以扩展Django的User模块，完全自定义新的认证模块。

from django.db import models
from django.contrib.auth.models import (
  BaseUserManager, AbstractBaseUser
)
class MyUserManager(BaseUserManager):
  def create_user(self, email, name, password=None):
    """
    Creates and saves a User with the given email, date of
    birth and password.
    """
    if not email:
      raise ValueError('Users must have an email address')

    user = self.model(
      email=self.normalize_email(email),
      name=name,
    )

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

  def create_superuser(self, email, name, password):
    """
    Creates and saves a superuser with the given email, date of
    birth and password.
    """
    user = self.create_user(
      email,
      password=password,
      name=name,
    )
    user.is_admin = True
    user.save(using=self._db)
    return user

class UserProfile(AbstractBaseUser):
  '''账号表'''
  email = models.EmailField(
    verbose_name='email address',
    max_length=255,
    unique=True,
  )
  name = models.CharField(max_length=32)
  is_active = models.BooleanField(default=True)
  is_admin = models.BooleanField(default=False)

  objects = MyUserManager()

  USERNAME_FIELD = 'email'
  REQUIRED_FIELDS = ['name']

  def __str__(self):
    return self.email

  def has_perm(self, perm, obj=None):
    "Does the user have a specific permission?"
    # Simplest possible answer: Yes, always
    return True

  def has_module_perms(self, app_label):
    "Does the user have permissions to view the app `app_label`?"
    # Simplest possible answer: Yes, always
    return True

  @property
  def is_staff(self):
    "Is the user a member of staff?"
    # Simplest possible answer: All admins are staff
    return self.is_admin
