Django - 使用带有信号的 django-registration 应用程序

Question

好的，所以我已经构建了一个基本的 Django 项目并成功安装了 django-registration 应用程序 - http://www.michelepasin.org/blog/2011/01/14/setting-up-django-registration/

我想扩展User 以包含生日、头像等信息。我创建了一个名为user_profile 的应用程序。这是注册应用程序中的signals.py：

from django.dispatch import Signal
user_activated = Signal(providing_args=["user", "request"])

在我的新应用程序user_profile 中，侦听此信号的方法是什么？我想我应该创建一个signals.py 文件，但是我应该在里面写什么？ from registration.signals import user_activated 声明还有什么？我创建的这个新应用还有一个 model.py，我想在激活新帐户时自动填充一些数据。

还有一个次要问题：当我将 URL 与基于类的视图链接时，会触发该类的哪个方法？如果我在基于类的视图中有 4 个方法，django 如何决定使用哪一个？谢谢

好的，如果我理解你的问题，你会在 user_profile/models.py 文件的末尾添加这样的内容：

from django.contrib.auth.models import User
from django.db.models.signals import post_save

def create_user_profile(sender, instance, **kwargs):
    """ 
        Function to create user profile. 
        sender is the model class that sends the signal,
        while instance is an actual instance of that class
    """

    # your own logic here, for example :

    user = instance
    profile = UserProfile()
    profile.user = user  # link the profile to the user
    profile.save()

# connect the function to the signal, for User instances)
post_save.connect(create_user_profile, sender=User)

对于第二个问题，在基于类的视图执行期间调用了许多方法。为了使用基于类的视图，您的 URLconf 应该如下所示：

from myapp import views
from django.conf.urls import patterns, url

urlpatterns = patterns('',
    url(r'list_something', views.YourListView.as_view(), name="list_something"),
)

但是你不应该在你的视图中覆盖as_view() 方法。根据您要执行的操作，您将有其他方法可以覆盖。如果您提供更多信息，我也许可以帮助您。

感谢艾略特，这是我目前所拥有的：

signals.py 现已删除。

models.py：

    import datime

from django.db import models
from django.contrib.auth.models import User

try:
    from django.utils.timezone import now as datetime_now
except ImportError:
    datetime_now = datetime.datetime.now

class UserProfileManager(models.Manager):

    def create_user_profile(self, user):
        user_profile = self.create(user = user)
        return user_profile

class UserProfile(models.Model):

    YEARS = tuple(zip(range(1900, datetime_now.year)), zip(range(1900, datetime_now.year)))
    MONTHS = (
              ('January','January'),('February','February'),('March','March'),('April','April'),
              ('May','May'), ('June','June'),('July','July'),('August','August'),
              ('September','September'),('October','October'),('November','November'), ('December', 'December')

             )
    GENDERS = (('M', 'Male'), ('F', 'Female'))

    user = models.ForeignKey(User, unique=True, verbose_name=_('user'))
    birthday_year = models.CharField(max_length=1, blank = True,  null = True, choices=YEARS)
    birthday_month = models.CharField(max_length=1, blank = True,  null = True, choices=MONTHS)
    gender = models.CharField(max_length=1, blank = True,  null = True, choices=GENDERS)
    creation_time = models.DateTimeField(auto_now_add = True, auto_now = False)
    update_time = models.DateTimeField(auto_now_add = False, auto_now = True)

    class Meta:
            verbose_name = _('user profile')
            verbose_name_plural = _('user profiles')

    objects = UserProfileManager()

def create_user_profile(sender, instance, **kwargs):
    profile = UserProfile.objects.create_user_profile(user=instance)
    profile.save()

post_save.connect(create_user_profile, sender=User)
