Comment (by Austin Roberts):
As I noted on #28168, I found a work around for this, though it would
still be great to have this work the same way as filter.
For now, I'm able to work around this by instead doing:
{{{
from django.db.models.expressions import OrderBy, RawSQL
MyModel.objects.all().order_by(OrderBy(RawSQL("metadata #> '{some}' #>
'{field}'", []))
}}}
Similarly, I have cases where I want to be able to do
{{{
MyModel.objects.all().values("metadata__some__field")
}}}
I've worked out a similar work around of
{{{
MyModel.objects.all().annotate(some_field=RawSQL("metadata #> '{some}' #>
'{field}'", [])).values("some_field")
}}}
