foreignKey in model based on condition in cakephp - mysql

Question

I am struck with one issue related to foreignKey concept.
I have two table users & user_relations.
users user_relations
id username id user_id friend_id status
1 abc 1 1 2 Accepted
2 def 2 2 3 Accepted
3 ghi 3 1 3 Accepted
here the friend_id is the foreign_key and my user_relations model looks like
public $belongsTo = array(
'Friend' => array(
'className' => 'User',
'foreignKey' => 'friend_id'
)
);
My conditions will be like
'conditions' => array(
"OR" => array(
'UserRelation.user_id' => $iLoggedUserId,
'UserRelation.friend_id' => $iLoggedUserId,
),
'ViewerRelationship.status' => 'Accepted'
)
Now when user "1" is logged in then he will get the info of users "2" & "3" based on foreignKey friend_id.
If user "2" gets logged in then, he is getting the info of users "2" & "3". But here I need to get the info of users "1" & "3". i.e., in one case it need to take the info based on the user_id not the friend_id
If I can keep the foreignKey in a condition I can get the result based on user_id or friend_id.
Any help please..!

I dont know how it is effective for you.
But it will solve your problem.
$respone = $this->UserRelation->find('all',
array('conditions'=> array(
'OR'=>array(
'UserRelation.user_id' => $iLoggedUserId,
'UserRelation.friend_id' => $iLoggedUserId
)
),
'fields' => array('UserRelation.*')
));
$reqFriendsId = array();
foreach($respone as $key => $val){
if($val['UserRelation']['friend_id'] == $iLoggedUserId){
array_push($reqFriendsId, $val['UserRelation']['user_id']);
}else{
array_push($reqFriendsId, $val['UserRelation']['friend_id']);
}
}
//For logged in user 1
Array
(
[0] => 2
[1] => 3
)
//For logged in user 2
Array
(
[0] => 1
[1] => 3
)
