django - Django auth 用户注册“用户”对象没有属性“配置文件”

问题描述

每次我注册新帐户时，我总是收到此错误“用户”对象没有属性“配置文件”，即使我复制了代码。我错过了什么？提前感谢谁会在这个问题上帮助我。

这是我的models.py

class Profile(models.Model):
    Pending_Request = [
        ('Active', 'Active'),
        ('Inactive', 'Inactive'),
    ]
    user = models.OneToOneField(User, related_name="profile", on_delete=models.CASCADE)
    bio = models.TextField(max_length=500, blank=True)
    Status = models.CharField(max_length=500, null=True, choices=Pending_Request, blank=True)
    def __str__(self):
        suser = '{0.user}'
        return suser.format(self)
@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)
    instance.Profile.save()

我的意见.py

def signup(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():
            user = form.save()
            user.refresh_from_db()
            user.profile.bio = form.cleaned_data.get('bio')
            user.save()
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=user.username, password=raw_password)
            login(request, user)
            return redirect('Homepage')
    else:
        form = SignUpForm()
    return render(request, 'customAdmin/signup.html', {'form': form})

解决方案

可能在您尝试访问的问题中未显示的某些代码中user.Profile，它应该是小写（user.profile），与您在 中设置的完全一样related_name。

此外，如果您更改相关模型中的某些内容，要保存更改，您应该调用相关模型上的.save()方法。像这样：

user.profile.bio = form.cleaned_data.get('bio')
user.profile.save()
