ORDER BY a json field fails in CTE select_from

class Foo(Model):
    data = BinaryJSONField()

# OK: Produces SELECT ... ORDER BY ("foo"."data"->>'x');
Foo.select().order_by(Foo.data['x'])

# NOK: Produces WITH foos AS (...) SELECT ... ORDER BY ("foos"."data" = 'x');
cte = Foo.select().cte('foos')
query = cte.select_from().order_by(cte.c.data['x'])

Ouch…that’s going to be rather difficult to fix, unfortunately, perhaps not possible. I’d suggest in the meantime trying something like:

.order_by(Expression(cte.c.data, '->>', SQL("'x'")))

Good suggestions, thank you.
