await obj_with_backling.fetch_all_links() does not work - not implemented yet?

[TutorExilius]

Hi there,

I would like to know why there is no option to fetch also BACKLINKs on demand, like its working with LINKs.

If I have a document, which contains Links, everything works like expected.
await document_with_link.fetch_all_links()

But this does not work witch documents witch backlinks.

The current solution is to use document.get/find/find_one... with the argument fetch_link=True.
But I need to fetch on my documents on demand (lazy loading).

I tried to fix the document.fetch_link() partially as follows:

async def fetch_link(self, field: Union[str, Any]):
        ref_obj = getattr(self, field, None)
        if isinstance(ref_obj, Link):
            value = await ref_obj.fetch(fetch_links=True)
            setattr(self, field, value)
        if isinstance(ref_obj, BackLink):
            await _fetch_backlink(field=field)
        if isinstance(ref_obj, list) and ref_obj:
            values = await Link.fetch_list(ref_obj, fetch_links=True)
            setattr(self, field, values)

    async def _fetch_backlink(self, field: Union[str, Any]):
        cls = ref_obj.model_class
        cls_field = self._link_fields[field].lookup_field_name
        query = {cls_field: {"$nin": [str(self.id)]}}
        owner = await cls.find_one(
            query
        )
        setattr(self, field, owner)

A dirty hack for a very spcial purpose, see the function async def _fetch_backlink(self, field: Union[str, Any]): ...
is there a chance that the "fetching-on-demand" works for "backlinks" in general in near future?
