Question

我正在尝试创建一个系统，在该系统中，完成注册后，系统会自动创建个人资料并将其保存给用户。我已经应用了所有当前知识，但是以下错误不断出现。

/ p /中的

IntegrityError NOT NULL约束失败：users_profile.standard

请求方法：POST

这是我的views.py-

from django.shortcuts import render, redirect
from django.contrib import messages
from .form import UserRegisterForm
from django.contrib.auth.decorators import login_required


def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(
                request, f'Your account has been created. You are now able to log in!')
            return redirect('login')
    else:
        form = UserRegisterForm()
    return render(request, 'users/register.html', {'form': form})


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

和我的signals.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 save_profile(sender, instance, **kwargs):
    instance.profile.save()

编辑-这是我的个人资料模型-

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 f'{self.user.username} Profile'
