Description (last modified by Jon Janzen)

With #34112 and #33646 combined, there is now an async interface for reading/writing Models in a lot of cases. One of the obvious places where that isn't true is in RelatedManager instances. RelatedManager instances are missing async versions of:

  • add
  • remove
  • clear
  • set

And this might be a separate ticket but the docs (1) are missing a reference to acreate which according to dir() exists on ManyRelatedManager (I assume as a consequence of inheriting from some superclass Manager type) but I didn't actually try and see if it works. I'm suspicious that it might not be fully correct as related_descriptors.py includes a possibly custom version of the synchronous create function (see (2) & (3)).

FWIW I'm also willing to work on a PR for this ticket, assuming a similar solution to #34112.

(apologies if this ticket is not well-formed or I missed another ticket that covers the same topics)
