使用信号扩展Django-Registration

Question

我在Stackoverflow上找到了一个解决方案，可以使用信号扩展使用新字段的Django Registration。这是链接： http://dmitko.ru/?p=546 .
我创建了扩展的配置文件模型，扩展表格，为设置，定义的URL添加了所需的选项，并且显示了正确的表单，但仅创建了正常用户（来自Auth Module）。为什么会发生？

account.models：

from django.db import models
from django.contrib.auth.models import User
from registration.signals import user_registered
import hashlib

class InheritedProfile(models.Model):
    first_name = models.CharField("Name", max_length=50, blank=True, null=True)
    last_name = models.CharField("Last name", max_length=50, blank=True, null=True)
    pid = models.CharField("PESEL", max_length=11, blank=True, null=True)
    street = models.CharField("Street", max_length=50, blank=True, null=True)
    number = models.CharField("Flat/house number", max_length=10, blank=True, null=True)
    code = models.CharField("Zip ", max_length=6, blank=True, null=True)
    city = models.CharField("City", max_length=50, blank=True, null=True) 
    class Meta:
        abstract=True

class UserProfile(InheritedProfile, User):
    def upload_path(self, field_attname):
        filename = hashlib.md5(field_attname).hexdigest()[:4] + "_" + field_attname
        return "uploads/users/%s" % (filename,)

    image = models.ImageField(upload_to=upload_path, verbose_name="Image", blank=True, null=True)

    def user_created(sender, user, request, **kwargs):
        form = ExtendedRegistrationForm(request.POST)
        extended_user = UserProfile(user=user)
        extended_user.is_active = False
        extended_user.first_name = form.extended_user['first_name']
        extended_user.last_name = form.extended_user['last_name']
        extended_user.pid = form.extended_user['pid']
        extended_user.image = form.extended_user['image']
        extended_user.street = form.extended_user['street']
        extended_user.number = form.extended_user['number']
        extended_user.code = form.extended_user['code']
        extended_user.city = form.extended_user['city']
        extended_user.save()

    user_registered.connect(user_created)

我需要这种继承的构件是抽象的，因为其他模型将使用相同的字段。

account.forms

from django import forms
#import strings
from registration.forms import RegistrationForm
from models import UserProfile, InheritedProfile

class ExtendedRegistrationForm(RegistrationForm):
    first_name = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="First name")
    last_name = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="Last name")
    pid = forms.RegexField(regex=r'^\d{11}', max_length=11 ,widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)))
    image = forms.ImageField(label="Image",)
    street = forms.CharField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=50)), label="Street")
    number = forms.CharField(widget=forms.TextInput, label="House/flat number")
    code = forms.RegexField(regex=r'^\d{2}[-]\d{3}', max_length=6, widget=forms.TextInput(attrs=attrs_dict), label="Postal code")
    city = forms.CharField(widget=forms.TextInput, label="City")

和添加到设置中的选项：

AUTH_PROFILE_MODULE = 'account.UserProfile'
ACCOUNT_ACTIVATION_DAYS = 7

最后，这就是注册信号的样子：

from django.dispatch import Signal
# A new user has registered.
user_registered = Signal(providing_args=["user", "request"])

编辑：user_created的凹痕没有任何改变，直到我尝试更改

user_registered.connect(user_created) 

到

user_registered.connect(user_created, sender=UserProfile)

现在我得到了：

即使我目前正在使用虚拟电子邮件后端。注册在注册时发送邮件功能解决了此问题，但仍未创建我的扩展用户。

问题可能是您如何连接信号的方式？在我的解决方案中是：

def user_created(sender, user, request, **kwargs):
    form = UserRegistrationForm(request.POST)
    data = profile.Profile(user=user)
    data.city_id = form.data["city"]
    data.save()

from registration.signals import user_registered
user_registered.connect(user_created)

在你的

from django.dispatch import Signal
# A new user has registered.
user_registered = Signal(providing_args=["user", "request"])

另外，我将打开日志记录，以确保调用您的方法。我的解决方案在制作中正常工作，如果您需要的话，我可以查找其他细节。
