django - 用户没有属性配置文件

Question

我目前正在尝试在他们注册并创建用户时创建用户配置文件，错误消息显示：RelatedObjectDoesNotExist 用户没有配置文件。

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

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

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

视图.py

from django.shortcuts import render, redirect
from .forms import UserRegisterForm
from django.contrib.auth import login
from django.contrib.auth.decorators import login_required


def register(request):
    if request.method != 'POST':
        form = UserRegisterForm()
    else:
        form = UserRegisterForm(data=request.POST)

        if form.is_valid():
            new_user = form.save()
            login(request, new_user)
            return redirect('blog:home')

    context = {'form': form}
    return render(request, 'user/register.html', context)


@login_required
def profile(request):
    return render(request, 'user/profile.html')

模型.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)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return self.user.username
