Comment (by Matthijs Kooijman):
Thanks for your responses.
> Thanks for the report, however I don't think a new hook is necessary
you can use ModelAdmin.autocomplete_fields to avoid selecting all related
instances to display in the dropdown, as documented:
I would not really consider that a solution of this particular problem. It
significantly changes UI (which might not be what I want here) which
prevents this prefetching from being needed, but IMHO does not really
solve the problem itself. But yeah, it does prevent the problem from being
a problem, that's true :-)
> Also, there are both established ways of optimising this and
customising choice generation (but these are topics for the Using
category on the Forum rather than here 🙂)
AFAICS those all work on the form end of things, which would be similar to
(maybe even more verbose than) the `formfield_for_foreignkey()`-based
approach I suggested above. However, the point of this ticket was to talk
about solving this more centrally on the original model side of things.
Having said that, I can see that fixing this is not easy and can be
considered out of scope, so closing as wontfix is perfectly acceptable.
Also, thanks for the links, I've learned a few new things from them :-)
