我目前正在開發一個博客Web應用程序，我試圖用一對一字段擴展我的Django用戶框架，一切都很好，但是當我嘗試注冊新用戶時，它會拋出TypeError。還值得注意的是，正在創建和存儲用戶（我從管理頁面進行了檢查）。它是說，我 views.py 的這一發言正在制造問題。profile.user = Profile.objects.get(user=request.user)我的 models.py：from django.db import modelsfrom django.contrib.auth.models import Userclass 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 views.pyfrom django.shortcuts import render, redirectfrom .models import Profilefrom django.contrib import messagesfrom django.contrib.auth.decorators import login_requiredfrom .forms import UserRegisterForm, ProfileFormdef 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!

我認為你寫的兩個信號是不必要的。此外，此行也不起作用：
profile.user = Profile.objects.get(user=request.user)
因為您尚未登錄。未登錄，您將無法在此處獲取用戶實例。但沒有必要。因為，您可以從另一個窗體獲取用戶實例。喜歡這個：
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})
另外，請務必刪除這兩個信號。
