Non-model field from data in Serializer DRF

I am trying to serialize an object where I would pass data which are non-model field into the serializer

    data = {
        'field1': 'abc',
        'field2': 123,
    }

    serializer = UserSerializer(
        user,
        context={"request": request},
        data=request.data,
        partial=True,
    )
    serializer.is_valid(raise_exception=True)
    result = serializer.validated_data

where I have a UserSerializer as such

class UserSerializer(serializers.ModelSerializer):
    field1 = serializers.SerializerMethodField()
    field2 = serializers.SerializerMethodField()

    class Meta:
        model = User
        fields = (
            'username',
            'field1',
            'field2',
        )

But I am getting empty DefaultDict() from the serializer.validated_data

you need to define that serializerMethod. Like

class UserSerializer(serializers.ModelSerializer):
    field1 = serializers.SerializerMethodField()
    field2 = serializers.SerializerMethodField()

    class Meta:
        model = User
        fields = (
            'username',
            'field1',
            'field2',
        )

    def get_field1(self, obj):
        value = self.context['request'].data.get('field1')
        return value
    def get_field2(self, obj):
        value = self.context['request'].data.get('field2')
        return value
