request.user得到的是自定义model

\#models.py 自定义的model

class MyUser(models.Model):  
    username = models.CharField(max\_length=32, verbose\_name=u'用户名')  
    is\_superuser = models.BooleanField(default=False, verbose\_name=u'是否是超级用户')  
    is\_active = models.BooleanField(default=False, verbose\_name=u'激活')  
    password = models.CharField(max\_length=128, verbose\_name=u'密码')  
    created = models.DateTimeField(auto\_now\_add=True, verbose\_name=u'创建时间')  
    last\_login= models.DateTimeField(auto\_now=True, verbose\_name=u'更新时间')  
      
    def \_\_unicode\_\_(self):  
        return self.username  
      
    def is\_authenticated(self):    
        return True    
   
    def hashed\_password(self, password=None):    
        if not password:    
            return self.password    
        else:    
            return hashlib.md5(password).hexdigest()    
            
    def check\_password(self, password):    
        if self.hashed\_password(password) == self.password:    
            return True    
        return False    
      
    class Meta:  
        verbose\_name = \_(u'管理员')  
        verbose\_name\_plural = \_(u'管理员')

\#auth.py 定义一个后端器，用于说明后端验证机制用到得是MyUser自定义model

class MyBackend:  
   
    def authenticate(self, username=None, password=None):    
        try:    
            user = MyUser.objects.get(username=username)    
        except MyUser.DoesNotExist:    
            pass    
        else:    
            if user.check\_password(password):    
                return user    
        return None    
     
    def get\_user(self, user\_id):    
        try:    
            return MyUser.objects.get(pk=user\_id)    
        except MyUser.DoesNotExist:    
            return None

\#settings.py 配置后端器  
AUTHENTICATION\_BACKENDS = (  
'myapp.auth.MyBackend',  
)
