所以我?guī)缀跬瓿闪宋业?Django 應(yīng)用程序。但是每當(dāng)我創(chuàng)建新用戶時(shí)，他/她的個(gè)人資料都不會自動創(chuàng)建，當(dāng)我在登錄后打開個(gè)人資料時(shí)，我會收到此錯誤RelatedObjectDoesNotExist at /esacp/profile/ User has no profile我的 signals.py 如下：from django.db.models.signals import post_savefrom django.contrib.auth.models import Userfrom django.dispatch import receiverfrom .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()我的 views.pyregister()和profile()如下：from django.shortcuts import render, redirectfrom django.contrib import messagesfrom .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateFormfrom django.contrib.auth.decorators import login_requiredfrom django.contrib.auth.models import Userdef 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 Student Account has been created! You can log in ESACP now.')            return redirect('login')    else:        form = UserRegisterForm()    return render(request, 'users/register.html', {'form': form})@login_requireddef profile(request):    if request.method == 'POST':        u_form = UserUpdateForm(request.POST, instance=request.user)        p_form = ProfileUpdateForm(request.POST,            request.FILES,            instance=request.user.profile)        if u_form.is_valid() and p_form.is_valid():            u_form.save()            p_form.save()            messages.success(request, f'Your Profile information has been updated.')            return redirect('profile')對我來說一切似乎都很好，任何人都知道出了什么問題或我錯過了什么？
