django 表示在创建用户时未创建用户配置文件

Question

我正在尝试创建一个简单的信号，在用户注册新帐户后为用户创建配置文件 object。 我错过了什么？

信号.py

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver
from .models import Profile
#from django_cleanup.signals import cleanup_pre_delete
#from sorl.thumbnail import delete

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance, bio="", linkedin_URL="", isCoach=False)

@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()

# def sorl_delete(**kwargs):
#     delete(kwargs['file'])

# cleanup_pre_delete.connect(sorl_delete)

应用程序.py

from django.apps import AppConfig


class EventsConfig(AppConfig):
    name = 'events'

    def ready(self):
        import events.signals

Answer 1

有时 django 信号在单独的文件中不起作用时尝试将信号代码放在您的 models.py 上，如下所示：

from django.db.models.signals import post_save
#signals_section
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance, bio="", linkedin_URL="", isCoach=False)

def save_profile(sender, instance, **kwargs):
    instance.profile.save()

post_save.connect(create_profile, sender=User)
post_save.connect(save_profile, sender=User)

要解决此问题，您可以将app's config添加到两个文件中的任何一个。

1. 在您的settings.py文件的INSTALLED_APPS中，如此链接中所述： Django create profile for user signal

或者，

2. 在相关app的__init__.py文件中，像这样（在本例中，相关应用是events ）： default_app_config = 'events.apps.EventsConfig'
