如何创建这些嵌套对象

Question

我有两个模型User和Vendor（它们与oneToOne链接，我想创建一个包含新User的Vendor。

问题，当我在我的VendorSerializer的重写方法create（）中使用方法User.objects.create（UserSerializer（），validated_data = user_data）时，我得到一个“ create（）接受1个位置参数，但给出了2个”错误

除了覆盖UserSerializer（）中的create之外，我还能做些什么？已经尝试过

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = (
            'first_name',
            'last_name',
            'email',
            'username'
        )

class VendorSerializer(serializers.ModelSerializer):
    user = UserSerializer(required=True)

    class Meta:
        model = Vendor
        fields = ('user','no_rue','adresse','code_postal','ville','pays')

    def create(self, validated_data):
        user_data = validated_data.pop('user')
        user = User.objects.create(UserSerializer(),validated_data=user_data)
        vendor, created = Vendor.objects.update_or_create(user=validated_data.pop('user'),no_rue=validated_data.pop('no_rue'),
        adresse = validated_data.pop('adresse'),
        code_postal = validated_data.pop('code_postal'),
        ville = validated_data.pop('ville'),
        pays = validated_data.pop('pays'))
        return vendor




class Vendor(models.Model):
    rating = models.FloatField(
        null=True,
        blank=True,
        validators=[MaxValueValidator(5),MinValueValidator(1)]
    )
    IBAN = IBANField(null=True,unique=True, default=None)
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    photo = models.ImageField(blank=True,null=True, upload_to='images') #Param: upload_to='directory'
    no_rue = models.PositiveIntegerField()
    adresse = models.CharField(max_length = 25)
    code_postal = models.PositiveIntegerField(validators=[MaxValueValidator(99999),MinValueValidator(1000)])
    ville = modelenter code heres.CharField(max_length = 25)
    pays = models.CharField(max_length = 25)
    def __str__(self):
        if(self.user.first_name == ""):
            return self.user.username
        else:
            return self.user.first_name
