“ about”是此函数的无效关键字参数

Question

我正在使用Django rest-framework，我使用API​​来向用户个人资料注册新用户，但是我收到此错误，不仅是关于字段，而且是用户个人资料模型中的其他字段，例如体重和身高，我包含了代码

这是我的模型。py

  class Meta:
        managed = True
        db_table = 'user'

class UserProfile(models.Model):
    weight = models.FloatField()
    height = models.FloatField()
    about = models.TextField(blank=True, null=True)
    license_number = models.IntegerField(unique=True)
    created = models.DateField(blank=True, null=True)
    updated = models.DateField(blank=True, null=True)
    #id = models.AutoField(unique=True)
    user_id = models.ForeignKey(User, models.DO_NOTHING)

    class Meta:
        managed = False
        db_table = 'user_profile' 

there are the serializers classes : 

class UserprofileSerializer(serializers.ModelSerializer):

    class Meta : 
        model = UserProfile
        fields =('weight','height','about','license_number','created','updated','id','user_id')


class  UserSerializer(serializers.HyperlinkedModelSerializer):
    profile = UserprofileSerializer(required = True)

    class Meta : 
        model = User 
        fields = ('id','first_name','last_name','email','password','user_type','created','updated','profile')
        extra_kwargs = {'password': {'write_only': True}}

    def create(self,validated_data):
        profile_data = validated_data.pop('profile')
        password = validated_data.pop('password') 
        user = User(**validated_data)
        user.set_password(password)
        user.save()
        User.objects.create(user=user,**profile_data)
        return user
