django-rest-auth 创建用户配置文件

Question

我正在使用 django-rest-auth to handle login and registration. The problem that I stumbled upon is that I'd like to add some custom fields to the default django User model. I've seen they covering this on their docs and I've tried replicating their example from here，但是当我从用户配置文件对新创建的字段发出 PUT 请求时，出现此错误：

RelatedObjectDoesNotExist at /rest-auth/user/
User has no userprofile.
Request Method: PUT
Request URL:    http://localhost:8000/rest-auth/user/
Django Version: 2.2.10
Exception Type: RelatedObjectDoesNotExist
Exception Value:    
User has no userprofile.

这是我的模型

from django.db import models
from django.conf import settings
from django.contrib.auth.models import User

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    company_name = models.CharField(max_length=100, default=None)

这是我的序列化程序：

from rest_framework import serializers
from rest_auth.serializers import UserDetailsSerializer


class UserSerializer(UserDetailsSerializer):

    company_name = serializers.CharField(source="userprofile.company_name")

    class Meta(UserDetailsSerializer.Meta):
        fields = UserDetailsSerializer.Meta.fields + ('company_name',)

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

        instance = super(UserSerializer, self).update(instance, validated_data)

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

我假设用户配置文件条目必须在用户创建的同时创建，但我不知道我应该怎么做。

Answer 1

from django.db import models
from django.conf import settings
from django.contrib.auth.models import User

from django.db.models.signals import post_save
from django.dispatch import receiver

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    company_name = models.CharField(max_length=100, default=None)

@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)
