使用 mongodb group

$ds = $this->getDataSource();
$key = array('file_type'=>1);
$options = array('user_id'=>(int)$user_id);
$initial = array('msum'=>0);
$reduce = "function(obj,prev) { prev.msum += obj.file_size; }"; 
$rs = $ds->group($this , array('key'=>$key  , 'initial'=>$initial , 'reduce'=>$reduce , 'options'=>$options));
