python - 添加last_name，first_name到默认的django_registration(不是redux)

Question

我使用 django-registration 1.0(我不确定，但我知道这是最新版本)所以，我想让用户在注册期间输入他自己的名字和姓氏，并将它们与其他(用户名、电子邮件、密码)发送给用户模型。所以我在 forms.py 中创建了自己的表单，它继承了默认的 django RegistrationForm，并添加了一些额外的字段

from registration.forms import RegistrationForm
from django.forms.fields import CharField
from django.contrib.auth.models import User

class UpdatedRegistrationForm(RegistrationForm):
    first_name = CharField(max_length=20)
    last_name = CharField(max_length=30)

class Meta:
    model = User
    fields = ('username', 'email', 'password1', 'password2')

def save(self, commit = True):
    user = super(UpdatedRegistrationForm, self).save(commit=False)
    user.first_name = self.cleaned_data['first_name']
    user.last_name = self.cleaned_data['last_name']
    if commit:
        user.save()
        return user

然后我将新表单放入urls.py

from django.conf.urls import include, url
from django.contrib import admin
from accounts.views import home_page, admin_panel
from accounts.forms import UpdatedRegistrationForm
from registration.views import RegistrationView

class RegistrationViewUniqueEmail(RegistrationView):
    form_class = UpdatedRegistrationForm

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^home/', home_page),
    url(r'^admin_pannel/',admin_panel),
    url(r'^register/$', RegistrationViewUniqueEmail.as_view(),               name='registration_register'),
url(r'', include('registration.backends.simple.urls')),
url(r'', include('social_auth.urls')),
]

当我运行我的服务器并访问 127.0.0.1:8000/register/ 时，我看到，额外的字段已添加到我的表单中 register form

然后我按注册，然后我看到一个错误 error 1但我也看到数据已发送。所以，我认为原因可能是没有重写 init() 方法。但我不知道该怎么做，所以可能还有另一个原因。请在这件事上给予我帮助。错误:

如果您使用简单后端，则应该从该后端对 View 进行子类化。您当前使用的是基本 RegistrationView，它没有实现 register 方法。

而不是导入

from registration.views import RegistrationView

你应该尝试

from registration.backends.simple.views import RegistrationView

django-registration 希望 have a new release soon ，但目前它已经有一段时间没有发布新版本了。最新版本可能不适用于最新版本的 Django，在这种情况下，使用 django-registration-redux 可能会取得更大成功。
