Where to set the author as request.user

Question

Problem

In my model I have the field author which I want to enter as a ForeignKey with the UserModel with the user who has authenticated himself via JWT Token. My API and JWT authentication works fine, but I don't know where to set the author = request.user in the backend.

My Code:

apis.py

class AlarmstichworteCreateApi(ApiErrorsMixin, APIView):
    permission_classes = [IsAuthenticated]

    class InputSerializer(serializers.ModelSerializer):

        author = UserListAPI.OutputSerializer(source='UserListAPI_set', many=True)
        created = serializers.DateTimeField()
        updated = serializers.DateTimeField()
        name = serializers.CharField(max_length=100)
        class Meta:
            model = AlarmstichworteConfig
            fields = (
                '__all__'
            )

    def post(self, request, *args, **kwargs):
        serializer = self.InputSerializer(data=request.data)
#!      serializer = self.InputSerializer(data=request.data, author=request.user) # Try 1
        serializer.is_valid(raise_exception=True)

        create_alarmstichwort(**serializer.validated_data)
#!      create_alarmstichwort(**serializer.validated_data, author=request.user) # Try 1

        return Response(status=status.HTTP_201_CREATED)

services.py

def create_alarmstichwort(
    *,
    author: ForeignKey,
    created: datetime,
    updated: datetime,
    name: str,

) -> AlarmstichworteConfig:

    if AlarmstichworteConfig.objects.filter(id=id).exists():
        raise ValidationError('Alarmstichwort existiert bereits')

    alarmstichwort = AlarmstichworteConfig.objects.create(
        author=author,
        created=created,
        updated=updated,
        name=name,
    )
    alarmstichwort.full_clean()
    alarmstichwort.save()

    return alarmstichwort

I would be happy if anyone could help me. Many thanks in advance!

Thank you for the clarification in the comments. If you remove the author field from the serializer, then pass it in as a parameter to create_alarmstichwort as you tried earlier with the value coming from request.user, you'll get the results you'd like. This does mean you'll need to stop using fields = "__all__".
