Django信号无法在usercreation上运行 [英] Django signals not working on usercreation

问题描述

我在 signals.py 文件中创建了一个信号，该信号应该为每个创建的用户创建一个配置文件，但是它不起作用.我试图检查命令 python manage.py check 是否存在错误，但这似乎也不起作用.

I created a signals supposed to create a profile for each created users in my signals.py file but it's not working. I've tried to check if there's an error with the command python manage.py check, but that seems not to work as well.

models.py

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


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    profile_pic = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return f"{self.user.username}'s profile "

signals.py

from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.auth.models import User
from .models import Profile


@receiver(post_save, sender=User)
def create_profile(sender, created, instance, **kwargs):
        if created:
                Profle.instance.create(user=instance)


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

apps.py

from django.apps import AppConfig


class UsersConfig(AppConfig):
    name = 'users'

    def ready(self):
        import users.signals

我在做什么错了?

推荐答案

问题出在我如何将用户应用安装在主项目目录的settings.py文件中.

The problem is from how i installed the users app in the settings.py file in the main project directory.

我用过:

INSTALLED_APPS = [
    'users',
]

**而不是**

INSTALLED_APPS = [
    'users.apps.UsersConfig',
]
