Django-registration - 如何从子类表单传递“extra_context”参数

Question

我使用的是Django Registration(https://bitbucket.org/ubernostrum/django-registration/)，需要在用户的注册中添加一些字段。

我已经创建了 RegistrationForm 的子类。我的“forms.py”如下：

from django.contrib.auth.models import User
from myproject.apps.userprofile.models import Gender, UserProfile
from myproject.apps.location.models import Country, City
from django import forms
from registration.forms import RegistrationForm
from registration.models import RegistrationManager


class RegistrationFormExtend(RegistrationForm):
    """
    Subclass of ``RegistrationForm`` which adds the fiedls in the userprofile app
    """   
    gender              = forms.ModelChoiceField(queryset=Gender.objects.all(), empty_label="(Nothing)")
    country             = forms.ModelChoiceField(queryset=Country.objects.all(), empty_label="(Nothing)")
    city                = forms.ModelChoiceField(queryset=City.objects.all(), empty_label="(Nothing)")
    #profile_picture     = 

为了使其正常工作，我通过将“form_class”参数添加到“注册”视图来更改“urls.py”以显示“RegistrationFormExtend”表单：

from django.conf.urls.defaults import *
from django.views.generic.simple import direct_to_template

from registration.views import activate
from registration.views import register

from myproject.apps.registrationextend.forms import RegistrationFormExtend


urlpatterns = patterns('',
               ...
                   url(r'^registar/$',
                       register,
                       {'backend': 'registration.backends.default.DefaultBackend', 'form_class': RegistrationFormExtend,},
                       name='registration_register'),
                   ...
                   )

在那之后，我进行了测试并且表单正在工作。用户注册成功，但“RegistrationFormExtend”中的所有额外字段（性别、国家、城市）都未存储在数据库中。

阅读文档，http://docs.b-list.org/django-registration/0.8/views.html#registration.views.register 看来我必须将参数“extra_context”传递给视图。

我的问题是如何将字典传递给“extra_context”参数。如何引用变量“gender”、“country”和“city”？

提前致谢。

您忘记在扩展注册表中使用save 方法。你必须这样做：

class RegistrationFormExtend(RegistrationForm):
    """
    Subclass of ``RegistrationForm`` which adds the fiedls in the userprofile app
    """   
    gender = forms.ModelChoiceField(queryset=Gender.objects.all(), empty_label="(Nothing)")
    country = forms.ModelChoiceField(queryset=Country.objects.all(), empty_label="(Nothing)")
    city = forms.ModelChoiceField(queryset=City.objects.all(), empty_label="(Nothing)")
    #profile_picture

    def __init__(self, *args, **kw):
       super(RegistrationFormExtend, self).__init__(*args, **kw)

    def save(self):
        #first save the parent form
        profile = super(RegistrationFormExtend, self).save()
        #then save the custom fields
        #i am assuming that the parent form return a profile
        profile.gender = self.cleaned_data['gender']
        profile.country = self.cleaned_data['country']
        profile.city = self.cleaned_data['city']
        profile.save()
        return profile
