Python django自定义注册视图，重定向失败

我正在使用Django注册，我已经将BaseRegistrationView子类化，以定制后端

但是，当满足条件时，HttpResponseRedirect无法重定向到新页面

代码如下所示：

class CustomRegistrationView(BaseRegistrationView):
  def register(self, request, **cleaned_data):
    captchaMatch = False

    #check captcha
    captchaValue = request.session.get('captcha')
    captchaValueSubmitted = cleaned_data['captcha'] + "123"

    if captchaValue != captchaValueSubmitted:
        return HttpResponseRedirect(reverse('InvitationRequired'))
    else:
        self.captchaMatch = True

    username, email, password = cleaned_data['username'], cleaned_data['email'], cleaned_data['password1']
    if Site._meta.installed:
        site = Site.objects.get_current()
    else:
        site = RequestSite(request)
    new_user = RegistrationProfile.objects.create_inactive_user(username, email,
                                                                password, site)


    signals.user_registered.send(sender=self.__class__,
                                 user=new_user,
                                 request=request)
    return new_user

def registration_allowed(self, request):
    """
    Indicate whether account registration is currently permitted,
    based on the value of the setting ``REGISTRATION_OPEN``. This
    is determined as follows:

    * If ``REGISTRATION_OPEN`` is not specified in settings, or is
      set to ``True``, registration is permitted.

    * If ``REGISTRATION_OPEN`` is both specified and set to
      ``False``, registration is not permitted.

    """
    return getattr(settings, 'REGISTRATION_OPEN', True)

def get_success_url(self, request, user):
    """
    Return the name of the URL to redirect to after successful
    user registration.

    """
    print "get successful url"
    if self.captchaMatch:
        return ('registration_complete', (), {})
    else:
        return HttpResponseRedirect(reverse('InvitationRequired'))

有人能解释一下为什么在函数register中执行重定向吗？

我想

register

方法应该返回一个用户或

None

。不是

HttpRedirect

对象。由于我不熟悉这个特定的应用程序，请尝试查看他们如何处理原始方法上的故障，并遵循该策略（即返回

None

或引发

异常

）

另外，根据

get\u success\u url（）

方法上的注释，我希望代码如下所示：

def get_success_url(self, request, user):
  """
  Return the name of the URL to redirect to after successful
  user registration.
  """
  if self.captchaMatch:
     return ('registration_complete', (), {})
  else:
     return ('InvitationRequired', (), {})

我想您不应该返回

HttpResponse

实例，因为该方法用于获取要重定向到的URL（而不是重定向本身）
