django - 属性错误 : 'User' object has no attribute 'check_password' error in Django?

Question

我有一个自定义模型，我正在尝试对其进行身份验证:

class User(models.Model):
    #id = models.IntegerField(primary_key=True)
    #identifier = models.CharField(max_length=40, unique=True, db_index=True)
    username = models.CharField(max_length=90, unique=True, db_index=True)
    create_time = models.DateTimeField(null=True, blank=True)
    update_time = models.DateTimeField(null=True, blank=True)
    email = models.CharField(max_length=225)
    password = models.CharField(max_length=120)
    external = models.IntegerField(null=True, blank=True)
    deleted = models.IntegerField(null=True, blank=True)
    purged = models.IntegerField(null=True, blank=True)
    form_values_id = models.IntegerField(null=True, blank=True)
    disk_usage = models.DecimalField(null=True, max_digits=16, decimal_places=0, blank=True)
    #last_login = models.DateTimeField()

    objects = UserManager()
    USERNAME_FIELD = 'username'
    #check_password(password)
    class Meta:
        db_table = u'galaxy_user'

我在“设置”中提到过这一点。

AUTH_USER_MODEL = 'fileupload.user'

 #views.py
        def login_backend(request):
            if request.method == 'POST':
                username = request.POST['username']
                password = request.POST['password']
                user = authenticate(username=username, password=password)
                if user is not None:
                    login(request, user)
                    return HttpResponseRedirect('/overview/')
                else:
                    return HttpResponseRedirect('/login_backend/')
            else:
                return render_to_response('login_backend.html', context_instance=RequestContext(request))

但是我收到了这个错误:

AttributeError: 'User' object has no attribute 'check_password' error 

我做错了什么？

如 custom user documentation 中所述，您的用户模型必须继承自 django.contrib.auth.models.AbstractBaseUser，它添加了所有相关方法。
