python - 当 User 模型更新 Django 时，如何更新我的 UserProfile 模型

Question

我有一个网站，需要更新我的 UserProfileInfo 模型，这就是我扩展用户模型的方式。但是，每当我保存用户模型时，UserProfileInfo 都不会，这意味着在管理中，用户模型已填写 first_name 和 last_name 变量，但是 UserProfileInfo 没有。

这是一些代码。

模型.PY

class UserProfileInfo(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE,max_length=30)
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    description = models.TextField(max_length=150)
    website = models.URLField(max_length=200,blank=True,null=True)
    image = ProcessedImageField(upload_to='profile_pics',
                                           processors=[ResizeToFill(150, 150)],
                                           default='default.jpg',
                                           format='JPEG',
                                           options={'quality': 60})
    joined_date = models.DateTimeField(blank=True,null=True,default=timezone.now)
    verified = models.BooleanField(default=False)
    moderator = models.BooleanField(default=False)

    tags = TaggableManager()

    def __str__(self):
        return f'{self.user.username} Profile'

    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)

@receiver(post_save, sender=User)
def create_or_update_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfileInfo.objects.create(user=instance)
    else:
        instance.userprofileinfo.save()

在接收器中，我想更新两者，但事实并非如此。

FORMS.PY

class UserProfileInfoForms(UserCreationForm):
    email = forms.EmailField()

    class Meta():
        model = User
        fields = ['username','first_name','last_name','email']

class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['username','email']

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = UserProfileInfo
        fields = ['image','description','tags','website']

最后是 View

VIEWS.PY

@login_required
def profile_update(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.userprofileinfo)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!')
            return redirect('mainapp:profile')

    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.userprofileinfo)

    context = {
        'u_form': u_form,
        'p_form': p_form
    }
    return render(request,'mainapp/profile_update.html',context)

所以在这里，我保存了 UserUpdateForm 和 ProfileUpdateForm

最后这是我的信号

SIGNALS.PY

@receiver(post_save, sender=User)
def create_or_update_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfileInfo.objects.create(user=instance)
    else:
        instance.userprofileinfo.save()

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

我还将我的 signals.py 包含在 apps.py 文件中，因此它可以正常工作。

那么如何才能在更新 User 模型时更新 UserProfileInfo 模型呢？我无法弄清楚这一点，因此我们将不胜感激
