New description:
It seems logical that, given a model Foo, with ArrayField bar, we should
be able to (using the same rules for querying), perform:
{{{
Foo.objects.order_by('bar__0')
}}}
However, this does not work. Is this something that _should_ be made to
work?
It is possible to perform this query using an OrderBy(RawSQL()) thing, but
that's a bit hard to figure out.
It's worth pointing out that the same limitation applies to Hstore fields,
and will apply to JSON fields.
At the very least, this should perhaps be documented?
