I implemented FilteredRawQuerySet which wraps around RawQuerySet and uses
QuerySet to generate WHERE / ORDER BY statements for raw queries:
https://github.com/Dmitri-Sintsov/django-jinja-
knockout/blob/master/django_jinja_knockout/query.py
It works with Django 1.8 to 1.11, but I had to fix it when database
queries code were refactored in Django 1.9. So I am worrying a bit that
new modifications can break it again.
Such querysets are useful when someone uses RAW queryset with ListViews
which automatically generate filter() / order_by() arguments.
There is also a ListQuerySet which allows to query Prefetch object results
as normal querysets. That allows to re-use the same code for different
related queries.
If that is possible, it would be great to move such feature into the core.
If the code is not good enough, then it could be reviewed and improved by
core committer - if someone is interested, of course.
