Question

所以，我正在尝试编写自己的注册后端，因为我必须和我遇到一些麻烦。

我明白了：

HttpResponse对象没有属性get_absolute_url

并且不知道如何解决这个问题。

这是我的代码：

class MyRegistrationBackend(object):

    def register(self, request, **kwargs):

        username, email, password = kwargs['username'], kwargs['email'], kwargs['password1']       

        encode_drupal = DrupalPasswordHasher()
        password = encode_drupal.create(str(password),"E","LOhihi6WNUA.")   #drupal style hasher
        print "sha512 pass: ", password
        #ask if user is already registered
        req = urllib2.Request(settings.DJANGO_SERVER+"/api/stats/customuser/"+username+"/?format=json",
            headers = {"Authorization": basic_authorization(settings.DJANGO_OAUTH_USERNAME, settings.DJANGO_OAUTH_PASSWORD),"Content-Type": "application/json"}
        )
        resp = json.loads(urllib2.urlopen(req).read())
        print resp
        if resp['username']!='':
           #do something

        else:
                if resp['password'] != password: #password does not match received pass
                    print "wrong credentials"
                    return render_to_response('registration/error.html')

  126.         return (user.get_absolute_url(), (), {})

Exception Type: AttributeError at /accounts/register/
Exception Value: 'HttpResponse' object has no attribute 'get_absolute_url'

有什么想法吗？我认为这与某些事情有关：

选择render_to_response

，但我不知道如何解决这个问题。

更新：

如果我返回None，我得到：

'NoneType'对象没有属性'get_absolute_url'

Answer 1

Django后端需要返回一个User对象（或具有get_absolute_url的等效对象），或者需要返回None (here's an example)。您的身份验证库不应该重定向，这是您的view'工作。

HttpResponse对象没有属性get_absolute_url
