First of of try to do each and everything using arrays wherever possible. It will maintain the spirit of CakePHP. Use following code :

$this->Message->find('all',
    array(
        'conditions' => array('Message.receiver_id'=>$user),
        'order' => array('Message.created' => 'Desc'),
        'group' => array('Message.user_id'),
        'field' => array('Message.user_id',...........)
    )
)

We use group by only if we have to perform some group function like sum, count etc...and fields option is compulsory.

Hello In a Message controller I try to display the latest message of each user (sender) for a connected one (receiver)  I try this but I still find the first entry. Thank you for your help

Messages table:

• id
  
• user_id -> Sender
  
• receiver_id -> receiver
  
• content 
  
• created -> datetime
  
• statut -> read or not
  

$this->set('messages', $this->Message->find('all',
array(
'conditions' => array('Message.receiver_id'=>$user),
'order' => array('Message.created desc'),
'group'=>'Message.user_id')));
