我的 Django 信号在哪里寻找在 createprofile 函数中创建的缺失参数？

如何解决我的 Django 信号在哪里寻找在 createprofile 函数中创建的缺失参数？

我在创建用户后使用 django 信号来创建配置文件，但是我收到这个错误，告诉我创建配置文件函数缺少创建的参数，我什至在没有装饰器的情况下尝试过，但它没有用。我不知道我错过了什么。

这是模型和信号本身。

 class Profile(models.Model):
    user = models.OnetoOneField(
        User,verbose_name="user",related_name="profile",on_delete=models.CASCADE
    )
    full_name = models.CharField(max_length=150,blank=True,null=True)
    date_of_birth = models.DateField(blank=True,null=True)
    bio = models.TextField()
    location = models.CharField(max_length=100,null=True)
    picture = models.ImageField(
        default="media/profile_pics/default.jpg",upload_to="media/profile_pics"
    )
    date_created = models.DateTimeField(default=timezone.Now)
    date_updated = models.DateTimeField(auto_Now=True)

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


@receiver(pre_save,sender=User)
def create_profile(sender,instance,created,**kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(pre_save,**kwargs):
    instance.profile.save()

我使用 django allauth 进行身份验证和授权。

这是来自终端的错误

解决方法

post_save 信号就是您在此处寻找的信号。

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