Comment (by Alex Scott):
Noumbissi, just wondering if you're working on this? And if so, how it's
progressing?
This problem (of needing to join to a subquery or add additional
conditions to a join that is nested more than once) seems to come up quite
a bit. I've posted my own question on StackOverflow:
https://stackoverflow.com/questions/58895627/django-queryset-with-
aggregation-and-filtered-left-join-multiple-levels-deep
In the absence of this feature, it'd be nice to have someone intimately
familiar with the ORM propose how they would tackle this as I haven't seen
a "this feature is not yet available, but as a workaround, try this
instead..". Would be very helpful.
