Django，新用户注册时创建用户配置文件时出错

Question

我正在通过遵循下面提到的Github存储库来开发一个Django网站。

当新用户注册时，它不会创建与之关联的配置文件，当我尝试访问配置文件时，我得到的响应为

RelatedObjectDoesNotExist at /accounts/profile/
User has no profile.

这里可能出了什么问题？

以下代码片段来自我的 Django 项目的users应用程序。

apps.py

class UsersConfig(AppConfig):
name = 'users'

def ready(self):
import users.signals

signals.py

@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()

models.py

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
address = models.CharField(max_length=500,null=True,blank=True)
phone = models.PositiveIntegerField(null=True,blank=True)

forms.py

class UserRegisterForm(UserCreationForm):
email = forms.EmailField()
class Meta:
model = User
fields = ['username', 'email', 'password1', 'password2']

class UserUpdateForm(forms.ModelForm):
email = forms.EmailField()
class Meta:
model = User
fields = ['username', 'email']

class ProfileUpdateForm(forms.ModelForm):
class Meta:
model = Profile
fields = ['address','phone']
