Strange extend_schema behaviour with pagination and custom action

[LesPrimus]

Hi

Let's say i have a view like this one:

class BookViewSet(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = serializers.BookSerializer

    @extend_schema(
        responses={200: inline_serializer(
            name='TitleSerializer',
            fields={'title': rest_serializers.CharField()},
            many=True
        )}
    )
    @action(methods=["GET"], detail=True)
    def get_title(self, request, *args, **kwargs):
        return Response()

    @extend_schema(
        responses={200: inline_serializer(
            name='GenreSerializer',
            fields={'genre': rest_serializers.CharField()},
            many=True
        )}
    )
    @action(methods=["GET"], detail=True)
    def get_genre(self, request, *args, **kwargs):
        return Response()

Here the schema is correct:

But here is not:

Must be:

{
  "count": 123,
  "next": "http://api.example.org/accounts/?offset=400&limit=100",
  "previous": "http://api.example.org/accounts/?offset=200&limit=100",
  "results": [
    {
      "genre": "string"
    }
  ]
}

Settings:

REST_FRAMEWORK = {
    'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema',
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.LimitOffsetPagination',
}

SPECTACULAR_SETTINGS = {
    'SWAGGER_UI_SETTINGS': {
            'filter': True,
            "displayOperationId": True,
        },
    'TITLE': 'MY PROJECT SETTINGS',
    'VERSION': '1.1.1',
}

Can you help me? or I'm missing something?

hi @LesPrimus. your example looks fine. it looks like a bug that happens only with pagination. i'll investigate.

[tfranzel]

that should fix it. small oversight in name generation for many=True aka ListSerializer

please confirm and close issue if resolved.

Confirm... Thanks so much!
