自定义django注册后端必须只有一个参数

我在这里绝对损失我做错了什么。我正在为django注册编写一个自定义后端，并且据我所知，我完全按照说明操作。我错过了什么论点来完成这项工作？自定义django注册后端必须只有一个参数

这是我的错误信息：

TypeError at /accounts/register/ 
CustomSignUpBackend() takes exactly 1 argument (0 given)

这里是我的回溯：

Environment: 


Request Method: GET 
Request URL: http://localhost:8000/accounts/register/ 

Django Version: 1.4.1 
Python Version: 2.7.3 
Installed Applications: 
('django.contrib.auth', 
'django.contrib.contenttypes', 
'django.contrib.sessions', 
'django.contrib.sites', 
'django.contrib.messages', 
'django.contrib.staticfiles', 
'django.contrib.admin', 
'api', 
'contact', 
'lessons', 
'mainsite', 
'piston', 
'registration', 
'utils') 
Installed Middleware: 
('django.middleware.common.CommonMiddleware', 
'django.contrib.sessions.middleware.SessionMiddleware', 
'django.middleware.csrf.CsrfViewMiddleware', 
'django.contrib.auth.middleware.AuthenticationMiddleware', 
'django.contrib.messages.middleware.MessageMiddleware', 
'django.middleware.clickjacking.XFrameOptionsMiddleware') 


Traceback: 
File "c:\Python27\lib\site-packages\django\core\handlers\base.py" in get_response 
    111.       response = callback(request, *callback_args, **callback_kwargs) 
File "c:\Python27\lib\site-packages\registration\views.py" in register 
    178.  backend = get_backend(backend) 
File "c:\Python27\lib\site-packages\registration\backends\__init__.py" in get_backend 
    32.  return backend_class() 

Exception Type: TypeError at /accounts/register/ 
Exception Value: CustomSignUpBackend() takes exactly 1 argument (0 given)

，这里是在urls.py相关线路：

url(r'^accounts/register/$', register, {'template_name': 'registration/registration_form.html', 'backend': 'lessons.backends.CustomSignUpBackend', 'form_class': MyRegistrationForm}, name='registration_register'),

，并终于在这里是自定义后端代码（在课程/后端/ init的.py）：

class CustomSignUpBackend(DefaultBackend): 

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

     username, email, password = kwargs['username'], kwargs['email'], kwargs['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) 
     return new_user

应该'高清TeacherSignupBackend（ARG）'是'类TeacherSignupBackend （parentClass）'？ –

是的，它做到了。谢谢 –

def TeacherSignupBackend(arg)应该是一流的TeacherSignupBackend(parentClass)

功能......从类的父类（ES）继承带参数
