It doesn't look like the mnesia erlydb driver supports ordering as
well as the other erlydb drivers do. For instance, this doesn't work:
newest(Top,First) ->
post:find({id,'>',1},
[{order_by,[{created_on,desc}]},
{limit,First,Top}]).
It fails with:
ERROR erlang code crashed:
File: appmod:0
Reason: "Unhandled extras"
Req: {http_request,'GET',{abs_path,"/post/newest"},{1,1}}
But this *does* work:
newest(Top,First) ->
post:find({id,'>',1},
[{order_by,created_on},
{limit,First,Top}]).
(Note the simplified ordering.) The former looks almost exactly like
the one under "Protection against SQL injection attacks" at <http://
yarivsblog.com/articles/2006/09/30/erlydb-0-7/>, so I would assume
that it would work
