Re: cakephp Messaging sysytem

Cool, but LastMessage isnt attaching.

Question, how can i join in this query the usarname that im talking (Condition like this: where user_id =/= my_user_id. Or first in the result row always be my user_id then i know the rest...)? Like Facebook, always show the another user, and not the user that created the conversation.

with joins and group statements it is easier to accomplish:

        function ownConversations($uid, $type = 'all') {
                $options = array(
                        'conditions' => array('ConversationUser.status
<'=>ConversationUser::STATUS_REMOVED),
                        'group' => array('ConversationUser.conversation_id HAVING SUM(case
when ConversationUser.`user_id` in (\''.implode('\', \'', $uid).'\')
then 1 else 0 end) = '.count($uid).''),
                        'contain' => array('Conversation' => array('LastMessage')),
                        'order' => array('Conversation.last_message_id'=>'DESC')
                );
                return $this->ConversationUser->find($type, $options);
        }
