Question

我正在使用Python（3.7）和Django（2.1）开发一个项目，在该项目中，我需要在创建用户时创建用户个人资料。

这是我尝试过的：

来自models.py：

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    avatar = models.CharField(max_length=500, null=True)
    about = models.CharField(max_length=1000, null=True)
    slogan = models.CharField(max_length=500, null=True)
    profile_pic = models.FileField(upload_to='media/profile_pics', null=True)

    def __str__(self):
        return self.user.username

来自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, created, **kwargs):
    instance.profile.save()

来自urls.py：

path('register/', views.RegisterUser.as_view(), name='register'),

来自views.py：

def post(self, request, *args, **kwargs):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            messages.success(request, f'Account has been created for {username}!')
            form.save()
            return HttpResponseRedirect(reverse_lazy('login'))

        else:
            form = UserRegisterForm()
        return render(request, 'users/register.html', {'form': form})

来自forms.py：

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

    class Meta:
        model = User
        fields = ('username', 'email', 'first_name',
                  'last_name', 'password1', 'password2')

来自apps.py：

class JobexpertappConfig(AppConfig):
    name = 'jobexpertapp'
    app_label = 'jobexpertapp'

    def ready(self):
        import jobexpertapp.signals

更新：我还通过使用django-social-auth在我的网站上使用了facebook身份验证，并且为了获取facebook头像，我实现了2件事，（a）定义了social_auth_pipeline.py（b）：添加SOCIAL_AUTH_PIPELINE在settings.py中：

所以

来自social_auth_pipeline.py：

def save_avatar(backend, user, response, *args, **kwargs):
    try:
        profile = Profile.objects.get(user_id=user.id)
    except Profile.DoesNotExist:
        profile = Profile(user_id=user.id)

    if backend.name == 'facebook':
        profile.avatar = 'http://graph.facebook.com/{}/picture?type=large'.format(response['id'])

    profile.save()

来自settings.py：

SOCIAL_AUTH_PIPELINE = (

    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
    # 'apps.users.pipeline.get_avatar',
    'jobexpertapp.social_auth_pipeline.save_avatar',
)

当我通过注册页面创建新帐户时，它会创建user，但不会创建配置文件。另外，创建用户时在控制台上找不到任何错误。这里有什么问题吗？

谢谢！

我遇到了同样的问题。

我的信号在类UsersConfig（AppConfig）中的'users'/'apps.py'中：

对我有用的是以下内容。在INSTALLED_APPS列表的project /'settings.py'中，我曾经用自己的名字（即“博客”，“用户”）列出我的应用程序。当我对此进行更改并改为这样列出它们时：“ blog.apps.BlogConfig”，“ users.apps.UsersConfig”，配置文件创建/保存在用户创建/保存时触发，因此可以正常工作。

Django 2.1在创建用户时创建配置文件
