Django实现自定义用户模块

Django中自带的User Model使用起来是比较方便的，但是一般跟我们系统的需求有些出入，或者少了一些必要的属性，或者多了些不必要的属性，这是就需要我们自己定义User Model，自定义用户模块。

虽然自定义了用户模块，但是不影响Django原有的用户认证体系。

1.

from django.contrib.auth.models import BaseUserManager, AbstractBaseUser

class ANUserManager(BaseUserManager):
    def create_user(self, username, password=None):
        """
        Creates and saves a User with the given 
        user name and password.
        """
        if not username:
            raise ValueError(_('Users must have an username'))

        user = self.model(
            username=username,
        )

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

    def create_superuser(self, username, password):
        """
        Creates and saves a superuser with the given  
        user name and password.
        """
        user = self.create_user(
            password=password,
            username=username
        )
        user.is_admin = True
        user.save(using=self._db)
        return user
    
    class Meta:
        verbose_name = _("System User")
        verbose_name_plural = _("System User")

2.

class SysUser(AbstractBaseUser, PermissionsMixin):
     username = models.CharField(max_length=100, null=False, verbose_name=_('用户名'), help_text=_('用户名'), unique=True, db_index=True )    
    email = models.EmailField(max_length=254, verbose_name=_('邮件地址'), help_text=_('邮件地址'), null=True, unique=False, blank=True)
    phone = models.CharField(max_length=20, verbose_name=_('电话'), help_text=_('电话'), null=True, blank=True, unique=True)
   
    objects = ANUserManager()
    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = []

    def has_perms(self, perm, obj=None):
        return True

    class Meta:
        verbose_name = _("用户")
        verbose_name_plural = _("用户")

3. 在settings.py中添加一句

AUTH_USER_MODEL = 'app.SysUser'
