Hello.
I have problem.
I can view tasks only autenticated user.
i have function:
public function defaultScope() {
        if (Yii::app()->user->checkAccess('admin')) {
            return array();
        } else {
        $alias = Task::model()->getTableAlias(false,false);
//            var_dump($tabAlias); die;
            return array(
                'condition' => $alias . ".user_id = '" . Yii::app()->user->id . "'",
            );
        }
    }
I have two tables. TASK and USER_ID.
My relation in task:
 public function relations() {
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
            'messages' => array(self::HAS_MANY, 'Message', 'task_id'),
            'project' => array(self::BELONGS_TO, 'Project', 'project_id'),
            'user' => array(self::BELONGS_TO, 'User', 'user_id'),
            'author' => array(self::BELONGS_TO, 'User', 'author_id'),
                //    'file' => array(self::BELONGS_TO, 'Files', 'path'),
        );
    }
My relation in Project:
public function relations() {
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
            'tasks' => array(self::HAS_MANY, 'Task', 'project_id'),
            'users' => array(self::MANY_MANY, 'User', 'user_project(project_id, user_id)'),
            'author' => array(self::BELONGS_TO, 'User', 'author_id'),
        );
    }
I render tasks in project.
and i need something that: task_id = Authenticated user_id.
But my error is:
CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't.user_id' in 'where clause'. The SQL statement executed was: SELECT COUNT(DISTINCT `t`.`id`) FROM `project` `t` LEFT OUTER JOIN `user_project` `users_users` ON (`t`.`id`=`users_users`.`project_id`) LEFT OUTER JOIN `user` `users` ON (`users`.`id`=`users_users`.`user_id`) LEFT OUTER JOIN `user` `author` ON (`t`.`author_id`=`author`.`id`) LEFT OUTER JOIN `task` `tasks` ON (`tasks`.`project_id`=`t`.`id`) WHERE (t.user_id = '49')
