Yep, it's possible. You just have to specify fields on containable:
$this->User->find('all', array(
'conditions' => array('User.id' => $id),
'fields' => array('id'),
'contain' => array(
'Profile' => array(
'fields' => array('id','type'),
'ProfileAttribute' => array(
'fields' => array('id'),
'AttributeName' => array(
'fields' => array('id','name'),
'Attribute' => array(
'fields' => array('id','value')
)
)
)
)
)
);
Be wary that when you use contain
and fields
options, you have to specify the id
so it can make the association (check the docs)
EDIT: I don't know if you can group contained data as the docs didn't say anything about that, but probably you can, as they accept some parameters as in the main query. You can try it, adding group
to any contained data that you want to group
