[Django]如何解决以下错误(in views.py)？

Question

在运行 howtotangowith django 站点的第九章中给出的代码，我在views.py 中得到以下错误：

Environment:
Request Method: POST
Request URL: http://127.0.0.1:8000/rango/register/

Django Version: 1.7
Python Version: 2.7.8
Installed Applications:
('django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',

 'django.contrib.auth.middleware.AuthenticationMiddleware',

 'django.contrib.messages.middleware.MessageMiddleware',
 'django.middleware.clickjacking.XFrameOptionsMiddleware')


Traceback:
File "C:\Users\Blue\Anaconda\lib\site-packages\django\core\handlers\base.py"        in get_response
  111.                     response = wrapped_callback(request,      *callback_args, **callback_kwargs)
File "C:\Users\Blue\code\tango_with_django_project\rango\views.py" in     register
  78.         user_form=UserForm(data=request.POST)

Exception Type: TypeError at /rango/register/
Exception Value: this constructor takes no arguments

用户表单代码：

class UserForm:
password=forms.CharField(widget=forms.PasswordInput())
class Meta:
    model=User
    fields=('username','email','password')

!!!! 不知道如何解决此错误，请帮助
