mysql - Sum and order by desc with query builder (laravel) -

-

i have som results of multiple table, selected 

$places = place::with(['rates' => function($query)     {         $query->select('id', 'place_id', 'criterion_id', 'value');      }])->select('id', 'coords')->get();

i need order reslut sum (or avg) of values. how can this? tried use 

$query->select('id', 'place_id', 'criterion_id', 'value')->sum('value');

but doesn't work.

i have such table

if works you. can use join instead of eager loading.

the code this:

place::leftjoin('rates', 'places.id', '=', 'rates.place_id')           ->selectraw('places.*, sum(rates.value) sumofratevalues')           ->groupby('places.id')           ->orderby('sumofratevalues', 'desc')           ->get();
