I have a issue on mongo db to getting records using group by '$group' in aggregate function on date as 'created' but we have datetime format in table mongoDb database.
when I run the mongo query I am getting error "can't convert from BSON type string to Date"
$date = date('Y-m-d',strtotime(-1 month));
$users = $this->common_model->aggregate($this->database['USER_DATA'], array(array('$match' => array('created' => array('$gte' => $date))),
array('$sort' => array('_id.created' => -1)),
array('$group' => array('_id' => array('year' => array('$year' => '$created'), 'month' => array('$month' => '$created'), 'day' => array('$dayOfMonth' => '$created')), 'count' => array('$sum' => 1))),
));
before we are using
array('$group' => array('_id' => array('created' => '$created')), 'count' => array('$sum' => 1)),
Its was working but records not as required as per group by date, because in table we have datetime.
