How to write a mysql query in cakephp referencing different tables - cakephp

Question

I have the tables USERS(id, email), MAIL(id, message, receiver, user_id), SERVICES(id, service, user_id)...
A user posts a service, the another user replies to that service through the mail. I want to write a query that will retrieve the email of the user that posted that particular service from USERS and capture it in the receiver field in MAIL when someone replies to the service.
I'm fairly new to cake, and have no idea where to go from here
$receiver = $this->User->find('first',array(
'conditions' => array(
'Users.user_id' => 'Services.user_id',
)
));
SQL Query
SELECT u.email FROM users AS u, services AS s WHERE s.user_id = u.id LIMIT 0 , 30

Assuming you have User.php model, create one action as shown below
function getData(){
$options = array(
//'conditions' => array(‘User.user_id’=>9),
'joins' => array(
array(
'alias' => 'Service',
'table' => ‘services’,
'type' => 'LEFT',
'conditions' => array(
'Service.user_id = User.id',
),
),
array(
'alias' => 'Mail',
'table' => ‘mail',
'type' => 'LEFT',
'conditions' => array(
'Mail.user_id = User.id',
),
)
),
'fields' => array('User.email'),
'limit'=>10
);
$returnData = $this->find('all',$options);
return $returnData;
}
From controller call this method as
$data = $this->User->getData();
print_r($data);
Hope it will solve your problem!
