Eloquent count() always returns 1

Question

I have the following query:

Item::select([\'items.id\', \'inventory.quantity\'])
    ->leftJoin(\'inventory\', \'items.id\', \'=\', \'inventory.item_id\')         


        

Answer 1

If you only need the correct number of rows from a grouped result, and you don't care that much about the performance then you can call get() first and then call count() on that.

$count = Item::select(['items.id', 'inventory.quantity'])
    ->leftJoin('inventory', 'items.id', '=', 'inventory.item_id')
    ->groupBy('items.id')
    ->get()
    ->count();

Answer 2

Yes, count returns only 1 row, always.

You would probably want:

Item::select(['items.id as id', 'inventory.quantity as quantity'])
 ->leftJoin('inventory', 'items.id', '=', 'inventory.item_id')
 ->groupBy('items.id')
 ->lists('quantity', 'id');

this will return an array with id as keys, and quantity as values. Otherwise use get, but never count if you want grouped results.
