注册用户时，在django注册中NotImplementedError [英] NotImplementedError in django-registration when registering a user

问题描述

我有一个django应用程序，并尝试使用 django-registration 应用程序。以下是我的设置和代码

settings.py

  INSTALLED_APPS =（
'django.contrib.auth'，
'django.contrib.contenttypes'，
'django.contrib.sessions'，
' django.contrib.sites'，
'django.contrib.messages'，
'django.contrib.staticfiles'，
'django.contrib.admin'，
'south' ，
'registration'，
'user_profile'，
）
 
 AUTH_PROFILE_MODULE =user_profile.UserProfile
 AUTHENTICATION_BACKENDS =（
'django .contrib.auth.backends.ModelBackend'，
）
  

项目 urls。 py 文件

  urlpatterns = patterns（''，
 url（r'^ admin /'， include（admin.site.urls）），
 url（r'^ accounts /'，include（'user_profile.urls'）），
 url（r'^ accounts /'，include .backends.default.urls'）），
）
  

user_profile urls.py 文件

  from registration.views import RegistrationView 
 
 urlpatterns = patterns（''，
 url（r'^ register / $'，registrationView.as_view （），
 {'backend'：'user_profile.backends.RegistrationBackend'}，
 name ='registration_register'），
）
  pre> 
 
 
  user_profile.backends.py 文件
  from .forms import RegistrationForm 
 from user_profile.models import UserProfile 
 from registration.views import RegistrationView 
 
 class RegistrationBackend（RegistrationView）：
 def get_form_class（s​​elf ，请求）
返回RegistrationForm 
 
 def注册（self，request，** kwargs）：
 kwargs [username] = kwargs [email] 
 user = super（RegistrationBackend，self）.register（request，** kwargs）
 UserProfile.objects.create（user = us呃）
 return user 
  
所以从上面的代码当用户点击url <$将显示c $ c> localhost：8000 / accounts / register  
a注册表单，并输入所有字段后（用户名，电子邮件，密码，密码），并点击注册按钮我得到以下 NotImplementedError  
  / accounts / register / 
中的NotImplementedError没有提供异常
请求方法：POST 
请求URL：http：// localhost：8000 / accounts /注册/ 
 Django版本：1.5.1 
异常类型：NotImplementedError

任何人都可以知道如何避免这个 NotImplementedError ，实际上是根据 python2.7 / site-packages / registration / views的原始视图。 py ，注册方法是
  def register（self，request，** cleaning_data）：

在这里实现用户注册逻辑。访问
请求和注册表单的完整的clean_data都可以使用
。 
 

 raise NotImplementedError 
  
但是我提供用于在我的网址中注册用户的后端类作为{'backend'：'user_profile.backends.RegistrationBackend'}，但仍然不会覆盖并显示原始功能错误。
 
 
 
所以我在上面的情况下做错了什么，如何修复并使用户保存？

解决方案
您不需要继承自引发NotImplementedError的方法。 
  def register（self，request，** kwargs）：
 UserProfile.objects.create ** kwargs）
返回用户
  
否则，你继承加注。 p> 
 
 
您的编辑是一个不同的问题。
 
 
 
看看在此。这是由于send_mail功能。我引用：
 
 
为了进行调试，您可以使用此
命令设置本地smtpserver：
 
 
 
 python -m smtpd -n -c DebuggingServer localhost：1025 
 
 
 
并相应调整邮件设置：
 
 
 
 EMAIL_HOST ='localhost'
 EMAIL_PORT = 1025 
 
 
 
这里记录了：测试电子邮件发送
 
 
 
I have a django app and trying to use django-registration app in it. And below are my settings and codes

settings.py
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin',
    'south',
    'registration',
    'user_profile',
 )

AUTH_PROFILE_MODULE = "user_profile.UserProfile"
AUTHENTICATION_BACKENDS = (
    'django.contrib.auth.backends.ModelBackend',
)
project urls.py file
urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^accounts/', include('user_profile.urls')),
    url(r'^accounts/', include('registration.backends.default.urls')),
 )
user_profile urls.py file
from registration.views import RegistrationView

urlpatterns = patterns('',
    url(r'^register/$', RegistrationView.as_view(),
        {'backend': 'user_profile.backends.RegistrationBackend'},
        name='registration_register'),
)
user_profile.backends.py file
from .forms import RegistrationForm
from user_profile.models import UserProfile
from registration.views import RegistrationView

class RegistrationBackend(RegistrationView):
    def get_form_class(self, request)
        return RegistrationForm

    def register(self, request, **kwargs):
        kwargs["username"] = kwargs["email"]
        user = super(RegistrationBackend, self).register(request, **kwargs)
        UserProfile.objects.create(user=user)
        return user
So from the above code when the user hits the url localhost:8000/accounts/register
a registration form will be displayed, and after entering all the fields(username,email, password, password) and clicked on register button i am getting the below NotImplementedError 
NotImplementedError at /accounts/register/
No exception supplied
Request Method: POST
Request URL:    http://localhost:8000/accounts/register/
Django Version: 1.5.1

  109.         raise NotImplementedError

Exception Type: NotImplementedError at /accounts/register/
Exception Value: 
can anyone know how to avoid this NotImplementedError, actually according to the original view at python2.7/site-packages/registration/views.py , the register method is 
def register(self, request, **cleaned_data):
    """
    Implement user-registration logic here. Access to both the
    request and the full cleaned_data of the registration form is
    available here.

    """
    raise NotImplementedError
But i am providing the backend class to use for registering the user in my url as  {'backend': 'user_profile.backends.RegistrationBackend'}, but still it is not overriding and displaying the origin functional error.

So what i am doing wrong in the above scenario and how to fix and make the user save ?

Edit                 

After modifying code as indicated by Paco

when tried to register the user i got below error
error at /accounts/register/

解决方案
You don't need to inherit from a method that raises NotImplementedError. Try this instead.
def register(self, request, **kwargs):
    UserProfile.objects.create(**kwargs)
    return user
Otherwise, you inheriting the raise as well.

Your edit is a different issue.

Have a look at this. It is due to the send_mail function. I quote:

  
For debugging purposes you could setup a local smtpserver with this
  command:
  
  
python -m smtpd -n -c DebuggingServer localhost:1025
  
  
and adjust your mail settings accordingly:
  
  
EMAIL_HOST = 'localhost'
  EMAIL_PORT = 1025
  
  
This is documented here: Testing e-mail sending
