Fetching records from Many to Many relationship does not work as expected in Phalcon

I have created the phalcon models and relationship as per they provided the document but getting the error "Notice: Undefined property: Phalcon\Mvc\Model\Resultset\Simple::$GroupsMembers in /var/www/html/uno/apps/webservice/controllers/UserController.php on line 245" while trying to fetch related records in many to many relationship.

I have 3 tables users, groups and group_members. group_members contain the relationship for groups and users.I want to get the all subscribed groups for a member therefore I have used below statements in UserController:


    $user = Users::find('id = '.$user_id);
    $subscribed_groups = $user->groupsMembers;
    foreach($groupMembers as $groupMember){
        echo $groupMember->groups->title;
    }

It gives the error mentioned above.

Please visit the link below to see my tables, models and controller.

Thank you Calin Rada (http://forum.phalconphp.com/user/283/calinrada) for answer.

Correct answer is:

find() method is returning an instance of Phalcon\Mvc\Model\Resultset\Simple but findFirst() will return an instance of your object (User in your case).

You use the alias GroupsMembers but then refer to it as $user->groupsMembers which is causing the undefined property notice.

Adjust your code to

$subscribed_groups = $user->GroupsMembers;

And it should work.
