Python/Django django-registration添加了一个额外的字段

Question

我已经阅读了很多关于如何在使用Django-registration时添加额外字段的内容,例如此处,此处和此处.代码片段是:forms.py(来自注册应用)

class RegistrationForm(forms.Form):
    username = forms.RegexField(regex=r'^\w+$', max_length=30, widget=forms.TextInput(attrs=attrs_dict), label=_("Username"), error_messages={ 'invalid': _("This value must contain only letters, numbers and underscores.") })
    email = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict, maxlength=75)), label=_("Email"))
    password1=forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False), label=_("Password"))
    institute=forms.CharField(max_length=50) #This is the new!
    password2 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False), label=_("Password (again)"))
    captcha = CaptchaField()

我使用django的注册保存方法,它在默认的后端:

def register(self, request, **kwargs):
    username, email, password = kwargs['username'], kwargs['email'], kwargs['password1']
    if Site._meta.installed:
        site = Site.objects.get_current()
    else:
        site = RequestSite(request)
    new_user = RegistrationProfile.objects.create_inactive_user(username, email,
                                                                password, site)

    signals.user_registered.send(sender=self.__class__,
                                 user=new_user,
                                 request=request)
    return new_user

在models.py中,我创建了一个新类:

class UserProfile(models.Model):  
    user = models.OneToOneField(User)
    institute=models.CharField(max_length=50)
def create_user_profile(sender, instance, created, **kwargs):  
    if created:  
        profile, created = UserProfile.objects.get_or_create(user=instance)
post_save.connect(create_user_profile, sender=User)

在admin.py中:

admin.site.unregister(User)
class UserProfileInline(admin.StackedInline):
    model = UserProfile
class UserProfileAdmin(UserAdmin):
    inlines = [ UserProfileInline, ]
admin.site.register(User, UserProfileAdmin)

我没有改变任何东西.当我渲染表格时,我可以看到我添加的研究所字段.当我在管理站点时,我可以看到每个用户的用户配置文件.但是,当我创建新用户时,通常保存用户的其他详细信息时,不保存任何内容.我认为我需要某种配置,但在哪里？也许在Django注册应用程序的文件中？

Answer 1

我已经找到了解决这个问题的方法,我会在这里发布,以防有​​人可以使用它.我想这很简单.

步骤1在models.py中添加一个新模型,它将是一个配置文件:

#models.py
class user_profile(models.Model):
     user=models.ForeignKey(User, unique=True)
     institution=models.CharField(max_length=200)

     def __unicode__(self):
         return u'%s %s' % (self.user, self.institution)

步骤2创建将使用此模型的表单:

#forms.py
from registration.forms import RegistrationForm
from django.forms import ModelForm
from Test.models import user_profile

class UserRegForm(RegistrationForm):
    institution=forms.CharField(max_length=200)

步骤3创建ragbackend.py并定义数据的保存方式:

from Test.models import user_profile
from forms import *

def user_created(sender, user, request, **kwargs):
    form = UserRegForm(request.POST)
    data = user_profile(user=user)
    data.institution = form.data["institution"]
    data.save()

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

步骤4转到urls.py并进行以下更改:

import regbackend 
from registration.views import register

url(r'^accounts/register/$', register, {'backend': 'registration.backends.default.DefaultBackend','form_class': UserRegForm}, name='registration_register'),
(r'^accounts/', include('registration.urls')),

请注意,您必须按顺序放置URL.容易理解为什么.

步骤5现在一切正常,但您无法在管理站点中看到这些信息.所以你必须去admin.py并添加:

#admin.py
from django.contrib.auth.models import User
from Test.models import user_profile
admin.site.unregister(User)
class UserProfileInline(admin.StackedInline):
    model = user_profile

class UserProfileAdmin(UserAdmin):
    inlines = [ UserProfileInline, ]
admin.site.register(User, UserProfileAdmin)

就是这样.别忘了syncdb以前runserver.我希望这会对某人有所帮助.

除了Garrett的回答之外,我在django-registration版本0.8中遇到了"无法导入名称注册"错误.我相信这是因为基于类的视图,因此更新urls.py:

from django.conf.urls import patterns, include, url
from registration.backends.default.views import RegistrationView
from abby.apps.accounts.forms import UserRegForm

urlpatterns = patterns('',
    url(r'^register/$', RegistrationView.as_view(form_class=UserRegForm)),
)
