Laravel Eloquent: sum with groupBy

Question

Need eloquent/fluent query to get sum with groupBy function.

So far I have tried:

    $this->data[\'no_of_pages\'] = Document::sum(\'no_of_pages\'         


        

Answer 1

Little bit refactored and convenient answer is (from @keroles Monsef)

Document::Where('some_condition',true)
    ->selectRaw("SUM(debit) as total_debit")
    ->selectRaw("SUM(credit) as total_credit")
    ->groupBy('id')
    ->get();
