我有一个我想要验证的自定义用户模型。该模型使用如下：
class GalaxyUser(AbstractBaseUser):
#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.TextField(max_length=255)
objects = UserManager()
USERNAME_FIELD = 'email'
class Meta:
db_table = u'galaxy_user'
我有自定义身份验证后端：
class AuthBackend:
def authenticate(self, username=None, password=None):
if '@' in username:
kwargs = {'email': username}
else:
kwargs = {'username': username}
try:
user = User.objects.get(**kwargs)
if user.check_password(password):
return user
except User.DoesNotExist:
return None
def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
视图中的login_backend函数如下所示：
def login_backend(request):
if request.method == 'POST':
username = request.POST['username']
password = request.POST['password']
password = hashlib.sha1(password).hexdigest()
user = authenticate(username=username, password=password)
state = "Username or Password Incorrect!"
if user is not None:
login(request, user)
return HttpResponseRedirect('/overview/')
else:
return render_to_response('login_backend.html', {'state':state}, context_instance=RequestContext(request))
else:
return render_to_response('login_backend.html', context_instance=RequestContext(request))
尽管输入了正确的用户名和密码，但我无法登录。有什么问题？

您不应该在视图中散列提交的密码。当您调用User.check_password方法时，后端会为您执行此操作。
