Question

我正在询问如何在模型用户中添加信号并知道该用户是否通过 Facebook 进行了注册，我的意思是，如果是新的用户< / strong>在Django中使用 Facebook 创建我想要捕获此事件并保存新的Customer模型。我相信这可能是那样的：

# SIGNALS AND LISTENERS from django.contrib.auth.models import User from django.db.models import signals from django.dispatch import dispatcher form customers.model import Customer # User def user_post_save(sender, instance, signal, *args, **kwargs): # Creates user profile if user # <- SOMETHGING LIKE IF USER IS LOGGED IN WITH FACEBOOK... customer = Customer.objects.get_or_create(owner=instance) dispatcher.connect(user_post_save, signal=signals.post_save, sender=User)

在评论中，您可以看到我需要的东西。谢谢你的帮助。

Answer 1

Django提供内置信号：pre_save，pre_init ...

使用它：

def password_change_signal(sender, instance, **kwargs):
    try:
        user = User.objects.get(username=instance.username)
        if not hasattr(user, 'userprofile'):
            print 'has no profile'
            return
        if not user.password == instance.password:
            print 'setting vals'
            profile = user.get_profile()
            profile.force_password_change = False
            profile.save()
    except User.DoesNotExist:
        pass

signals.pre_save.connect(password_change_signal, sender=User,dispatch_uid='members.models.UserProfile')

根据此SO POST，您可以使用post_save.connect()在创建用户时保存客户对象。请注意，我已根据您的要求在上述帖子中粘贴和编辑了代码。

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

def create_customer(sender, **kwargs):
    user = kwargs["instance"]
    if kwargs["created"]:
        customer = user.models.Customer()
        customer.setUser(sender)
        customer.save()

post_save.connect(create_customer, sender=User)

Django Signal用户注册facebook时
