Laravel ordering a relation -

i have following query thread , messages:

$thread = thread::with('messages.user.zone')             ->with('participants.user')             ->findorfail($id); 

.

i want thread messages ordered it's created_at property desc.

currently order oldest new (asc)

how can that? tried ->orderby('messages.created_at') no luck

this should work:

->with(['messages' => function($q) {     $q->orderby('created_at', 'desc'); }, 'messages.user.zone'])
