How to use distinct query using this library? I want to fetch distinct values of fields from collection. There is a function for distinct in library. I have used function from controller by below code.

$logs = $this->mongo_db->distinct('logs', 'log_section');
echo "<pre>";print_r($logs);exit;

Here logs is collection name and log_section is field name but i am getting below error

A PHP Error was encountered
