/register/ 处的类型错误'AnonymousUser'对象不可迭代

Question

我目前正在开发一个博客web应用程序，并试图用一对一字段扩展我的Django用户框架，一切都很好，但当我试图注册新用户时，它会抛出TypeError。同样值得注意的是，用户正在被创建和存储(我从管理页面检查了它(。

在我看来，这句话profile.user = Profile.objects.get(user=request.user)造成了问题。

我的模型.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')
CHOICES = (
('AB+', 'AB+'),
('AB-', 'AB-'),
('A+', 'A+'),
('A-', 'A-'),
('B+', 'B+'),
('B-', 'B-'),
('O+', 'O+'),
('O-', 'O-'),
)
bloodgroup = models.CharField(max_length=100, choices= CHOICES)
bio = models.TextField(max_length=300)
def __str__(self):
return f'{self.user.username} Profile'

我的观点.py

from django.shortcuts import render, redirect
from .models import Profile
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .forms import UserRegisterForm, ProfileForm

def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
profile_form = ProfileForm(request.POST)
if form.is_valid() and profile_form.is_valid():
form.save()
profile = profile_form.save(commit=False)
profile.user = Profile.objects.get(user=request.user)  
profile.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()
profile_form = ProfileForm
return render(request, 'users/register.html', {'form': form, 'profile_form': profile_form})
@login_required
def profile(request):
return render(request, 'users/profile.html')

我的信号.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 save_profile(sender, instance, **kwargs):
instance.profile.save()

我认为您编写的两个信号是不必要的。此外，这条线路也不起作用：

profile.user = Profile.objects.get(user=request.user)  

因为您尚未登录。如果没有登录，就无法在此处获取用户实例。但没有必要。因为，你可以从另一个表单中获取用户实例

def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
profile_form = ProfileForm(request.POST, request.FILES)
if form.is_valid() and profile_form.is_valid():
user = form.save()
profile = profile_form.save(commit=False)
profile.user = user  
profile.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()
profile_form = ProfileForm()
return render(request, 'users/register.html', {'form': form, 'profile_form': profile_form})

还要确保删除这两个信号。
