Python/Django django-registration 添加一个额外的字段 [英] Python/Django django-registration add an extra field

问题描述

我已经阅读了很多关于如何在使用 Django 注册时添加额外字段的信息，例如 这里，这里 和 此处.代码片段是:forms.py(来自注册应用程序)

I have read a lot about how to add an extra field when using Django-registration, for example here, here and here. The code snippets are: forms.py (from the registration app)

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()

我使用的是django的注册保存方式，在默认后台:

I use the django's registration save method, which is in the default backend:

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:

In models.py I have created a new class:

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:

In the admin.py:

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

我还没有改变任何东西.当我呈现表单时，我可以看到我添加的 Institute 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，那里没有保存任何内容，而用户的其他详细信息通常会保存.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?

I have not altered anything alse. When I render the form I can see the Institute Field I have added. When I am in the admin site I can see the user profile of each user. However nothing is saved there when I create a new user while the other details of the user are normally saved. I think that I need some kind of configuration but where? Maybe in the files of the Django-registration app?

推荐答案

我已经找到了解决这个问题的方法，我会把它贴在这里，以防有人可以使用它.这很简单，我想.

I have figured out a solution to this problem, and I will post it here in case somebody can use it. It's pretty simple, I suppose.

步骤 1 在 models.py 中添加一个新模型，即配置文件:

Step 1 Add a new model, which will be a profile, in the models.py:

#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)

第 2 步创建将使用此模型的表单:

Step 2 Create the form that will use this model:

#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:

Step 3 Create ragbackend.py and define how the data will be saved:

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:

Step 4 Go to urls.py and make the following changes:

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，您必须按该顺序放置 URL.很容易理解为什么.

Note that you have to put the URLs in that order. Easy to understand why.

第 5 步 现在一切正常，但您看不到管理站点中的信息.所以你必须去 admin.py 并添加:

Step 5 Now everything works, but you cannot see the information in the admin site. So you have to go to admin.py and add:

#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.不要忘记 runserver 之前的 syncdb.我希望这会对某人有所帮助.

And that's it. Do not forget the syncdb before runserver. I hope this will help someone.
