rest-auth 中的自定义用户模型：RelatedObjectDoesNotExist

Question

我正在尝试使用 django rest-auth library. I followed every instruction from the installation and usage guide, including the part with a custom user serializer 实现注册。和这里问题开始了。我们注册一个新用户，确认电子邮件，当我尝试更新用户时，我得到同样的错误：

"RelatedObjectDoesNotExist at /rest-auth/user/ User has no userprofile."

我不知道如何进行注册以同时为他创建用户和个人资料。我知道之前有人问过这个问题，但我没有找到任何可以解释为什么会这样的问题。我正在寻找使用 django-rest-auth 和自定义用户模型

进行注册的简单工作示例

models.py:

class UserProfile(models.Model): 
     user = models.OneToOneField(User, primary_key=True, related_name='profile')
     tagline = models.CharField(max_length=140, null=True)
     created_at = models.DateTimeField(auto_now_add=True)
     updated_at = models.DateTimeField(auto_now=True)

     @receiver(post_save, sender=User)
     def create_profile_for_user(sender, instance=None, created=False, **kwargs):
        if created:
            UserProfile.objects.get_or_create(user=instance)

     @receiver(pre_delete, sender=User)
     def delete_profile_for_user(sender, instance=None, **kwargs):
        if instance:
           user_profile = UserProfile.objects.get(user=instance)
           user_profile.delete()

serilizers.py

class UserSerializer(UserDetailsSerializer):
    curriculumVitaeLink = serializers.CharField(source="userprofile.curriculumVitaeLink", required=False)
    class Meta(UserDetailsSerializer.Meta):
        fields = UserDetailsSerializer.Meta.fields + (
            'curriculumVitaeLink'
        )

    def update(self, instance, validated_data):
        profile_data = validated_data.pop('userprofile', {})
        curriculumVitaeLink = profile_data.get('curriculumVitaeLink')
        instance = super(UserSerializer, self).update(instance, validated_data)

        # get and update user profile
        profile = instance.userprofile
        if profile_data :
            profile.curriculumVitaeLink = curriculumVitaeLink
            profile.save()
        return instance

    def destroy(self, request, pk=None, **kwargs):
        request.user.is_active = False
        request.user.save()
        return Response(status=204)

Answer 1

您应该使用您在 OneToOneField 中使用的 related_name 获取 userprofile 对象因此：

profile = instance.userprofile

应该是：

profile = instance.profile

Answer 2

RelatedObjectDoesNotExist这里的错误是指在创建User对象时没有通过信号创建相应的UserProfile对象。根据问题中的片段，可能是因为信号是如何定义的：

Django 信号需要在模块级别定义，而不是作为模型实例方法 - 您需要将缩进向左移动：

 class UserProfile(models.Model): 
     user = models.OneToOneField(User, primary_key=True, 
     related_name='profile')
     tagline = models.CharField(max_length=140, null=True)
     created_at = models.DateTimeField(auto_now_add=True)
     updated_at = models.DateTimeField(auto_now=True)


 @receiver(post_save, sender=User)
 def create_profile_for_user(sender, instance=None, created=False, **kwargs):
    if created:
        UserProfile.objects.get_or_create(user=instance)

这样 User 和 UserProfile 对象都应该在注册时创建。
